Home Theater Sound Systems

mutsav — Sun, 28 Feb 2010 03:43:15 +0000

There is nothing like watching a great movie on the big screen. Really though, a movie is not actually that great if you do not have good quality sound to go with it. Many people are investing in the equipment to create home theaters, especially with the drastic price drops that have occurred with regard to equipment over the years. If you are among that population or you are just looking to update your existing home theater sound system, there are several excellent options available to you in regard to audio equipment.

A good quality audio system is closely tied to the speakers and this is where you definitely want to spend some time in order to choose the right speakers. There are a lot of really nice speakers out there, but not all speakers combine style and functionality together in the same way. Some speakers produce excellent sound, but are designed in such a way that they do not complement any decor and therefore need to be hidden. Not that there is necessarily anything wrong with hiding speakers. In fact, there are speakers that are designed to be hidden, and in that way there is never any issue of speakers clashing with the decor in a room.

Of course installing these “invisible” speakers takes a bit more effort than traditional speakers, but the final result is well worth the effort. In fact, you can purchase entire audio systems including amplifiers, subwoofers and receivers that can all be mounted in a way that they are virtually invisible. These units work especially well for new room installation. Since the frame of the speakers can be mounted directly to the inside of the stud, all anybody will ever see is the front of the speaker, and not even that if that is not the look you are going for.

An additional benefit of mounting speakers in this manner is that the sound clarity is improved since vibration is reduced because of the way it is mounted. You also have some interesting options if you buy speakers that can be mounted on glass. Glass can be used to frame your large screen television and then the speakers can be mounted into the glass and the wires hidden in a manner that results in a very stylish entertainment system.

It does not take a large amount of technical expertise in order to install these types of speakers. A basic knowledge of electrical wiring for speakers and how to mount the speakers securely are the basic requirements. Most speakers come with detailed wiring and installation instructions, so if you run into a difficulty during the installation process, you have those to fall back on.

A home theater sound system can bring a whole new dimension of enjoyment to your favorite movies. It is important the audio system be properly installed, but also that it looks nice and meshes well with your decor. “Invisible” speakers are an excellent way to cover all of these needs in an affordable manner.

How to Cure a Smelly Pair of Shoes

Frank Stevens — Tue, 09 Feb 2010 17:22:00 +0000

If you have a pair of shoes that stink, you may think the situation is hopeless and you must get rid of the smelly shoes. But getting rid of a stinky pair of shoes is not the only option for dealing with the odor. The more you wear a pair of shoes, the more sweat and bacteria build up in the interior of the shoe. It is the sweat and bacteria build up that causes the foul smell. If you have a pair of shoes that you use for exercise, these shoes can be especially prone to smelling bad since they are used frequently and when they are used you are probably producing a lot of foot sweat. Thankfully, there are solutions for ridding your shoes of a yucky smell.

Many people think that a pair of fabric shoes can be simply thrown into the washing machine to get them clean and smelling fresh. However, this is not always a good idea because washing your shoes in a household clothing washer can warp or ruin your shoes.

One thing that will kill the odor causing bacteria in your shoes is freezing temperatures. So, while putting your shoes in the freezer may sound silly, this can instantly freshen up a pair of foul smelling shoes. Make sure that you shake or brush off any loose dirt on the shoes before you put them in your freezer. Also, you may wish to wrap your shoes in plastic wrap or place them in a plastic grocery sack before putting them in your freezer as well. Some people might feel a bit squeamish about putting a pair of stinky shoes in such close proximity to food they will some day be eating.

Additionally, before you place the shoes in the freezer, sprinkle the interior generously with baking soda. Shake the baking soda around to evenly distribute it throughout the shoes. You should leave your shoes in the freezer overnight to ensure they have been exposed to freezing temperatures long enough to kill the bacteria. When you take the shoes out of the freezer the next morning, you should let them warm up before wearing them. You can shake the excess baking soda into the trash can, but leaving a little baking soda in the interior of the shoe is not going to hurt the shoe. In fact, leaving a little bit of baking soda inside the shoe may help prolong the freshness of your shoes so you will not have to freeze them again so quickly the next time.

If you are lucky enough to live in a climate where the weather reaches freezing levels, you can simply place your shoes outside. This will have the same bacteria killing effect as placing your shoes in the freezer. You can follow the same baking soda placement procedure as stated above. When placing your shoes outside, make sure you put them in a sealed plastic bag so they do not collect moisture which will obviously turn into frost.

A Bit About Glass

Frank Stevens — Sun, 07 Feb 2010 19:49:50 +0000

As you look around your house, your work, and anywhere else you might happen to be, you will see that glass is used in many places. You can see glass in the windows, in the refrigerator shelves, on the face of your watch, on a flat top stove, and in the cups in your cupboard. Glass has many uses and is the preferred material for many of the objects that we use every day. Human beings have been using glass in different ways for thousands of years. Scientists are always looking at glass for future uses.

The word “glass” technically refers to several different materials, all with the characteristics of being brittle and at least partially transparent. The most common glass is made from silicon, which is found in quartz sand. The sand is mixed with a few other ingredients and heated to a high temperature. The ingredients melt together to create molten glass. The glass is then shaped through a number of methods, such as blowing or pressing to create jars, mirrors, windows, and everything else made of glass. Specialized glass products start out with this process, and have some kind of extra ingredient added at the end to give it the desired property, such as bulletproof glass, anti-reflective glass, and windshields.

Man, in one form or another, has used Glass since before history was recorded. Stone Age man was using obsidian, a volcanic glass, for weapons and cutting tools. The Egyptians and Mesopotamians were the first civilizations to turn glass into an art form, starting with simple beads and growing to glass pots, pitchers, and sculptures. As civilizations grew and faded, the art was lost and found again several times, being taken up by the Greeks, the Romans, and then coming to modern times. Before mass manufacturing, glass windows and other products were reserved for the wealthy and powerful. After the industrial revolution, glass making became easy to do on a large scale, and glass was suddenly available for anything it might be needed for.

Glass has come a long way over the centuries. Today, glass can be made in the laboratory to be almost absolutely transparent (well beyond what the human eye can detect), or can be given other properties to focus lasers, pass certain colors of light, or do anything else required for precision instruments. Glass can be shaped to magnify objects or can be given coatings or backings to make mirrors. Glass is used in some electronics components for its conductive properties. The most advanced techniques allow glass to be worked with at the microscopic level.

Glass is found almost everywhere you look. Glass is an extremely useful material that cannot be replaced in some instances. The material has played an important role in human history, giving artists and artisans a medium to create works of art and the window, which allows us to see through walls without having to be exposed to the elements. Just look around. You will see clear as day that glass is abundant.

The Gift of Luggage

Frank Stevens — Sun, 07 Feb 2010 18:48:19 +0000

Looking for something special to give your husband, son, daughter, mother, father, sister, brother, cousin, or best friend for their birthday, graduation, Christmas, Father’s Day, Mother’s Day, or any other gift-giving occasion? Thousands of gift ideas exist, but one is often overlooked: Luggage. Everybody travels in some capacity. Whether it is a short business trip, a vacation, a sleep over, going to work, going to school, or moving, everybody has a need for quality pieces of luggage to move their belongings from one point to another.

What should you buy when the time comes to give a person luggage as a gift? That of course depends on whom you are buying the gift for and how you envision them using the items. Is the gift for a man or a woman? Is the person younger or older? Will the person be using the bags for traveling, going to work, or going to school? Once you have these basic questions answered, you can begin your search for the perfect gift.
Everyone loves backpacks. A backpack is one of the most useful contraptions that man has ever invented. You can fit a host of belongings in the bag then you can strap it on to your back to carry with you so that your hands remain free. The device is simple, yet elegant. If the target of your gift is a student, a camper, or a casual traveler, a backpack is a great choice. Backpacks come in different styles. Some are very basic, with a simple compartment and shoulder straps. Others have more options, and might come with multiple compartments, a drink holder, and even straps that hook around the user’s waist to allow more weight to be supported comfortably. Backpacks come in many different materials, the most popular being leather, vinyl, and nylon. The color and material should fit the personality of the person receiving the gift and its intended use.

Wheeled bags are also useful in many situations. If the person you are giving the gift to already has a good backpack, or if the backpack is not appropriate, you might consider a wheeled bag. These are a new take on the old suitcase. Wheeled bags are usually simple rectangular bags with a hard outside to keep the rectangular shape. They come equipped with wheels on the bottom and a telescoping handle at the top. This allows the user to extend the handle and pull the back behind him as it rolls on its wheels. These bags are very useful when traveling. Small to medium sized wheeled bags can be carried on to an airplane. Larger wheeled bags can hold enough clothes to last many days and can always be checked in at the airport. Business people who do not want a backpack to wrinkle a shirt use wheeled bags to carry laptop computers and documents when traveling from home to the office.

Luggage is the perfect gift for almost anybody. Everybody can use some type of bag. If you are looking for a great gift for somebody you care about, you cannot go wrong with a nice piece of luggage.

Carbonless Paper: The Method Behind The Magic

Frank Stevens — Fri, 05 Feb 2010 07:42:52 +0000

When I was a child, I loved playing with carbon paper. There was something so fascinating about writing on a sheet of paper and having an exact copy of what I had written or drawn appear on another piece of paper beneath my original masterpiece. I remember going through a phase where I had to do all of my homework using carbon paper and all of my drawing required carbon paper as well. I am sure my mother appreciated the extra copy of every single spelling list and the thousands of variations on a rainbow scene. I even went through a phase where I would use the carbon paper wrong side up and have a copy of the inverse of whatever I was writing or drawing on the back of my paper. Obviously, I was a very creative child.

Even at a very young age, it seemed obvious how carbon paper worked. You put a piece of carbon paper between two pieces of writing paper. There was some type of ink on one side of the carbon paper and, when your pressed hard enough with a writing instrument on the top sheet, this ink would transfer onto the second sheet of paper. Voila! You have a “carbon copy”! Carbon paper used to be everywhere, used by teachers, accountants, and most memorably merchants. Probably everyone remembers those credit card receipts that had a piece of carbon paper between two pieces of what seemed like a credit card form printed on tissue paper.

Today, carbon paper is rarely seen anymore, especially in the world of credit card receipts and other types of merchant forms. Now, there is such a thing as “carbonless paper”. It seems like magic, this carbonless paper. Two pieces of paper with nothing in between and two exact copies are created. How does it happen?

Carbonless paper is actually a fairly simple invention. Carbonless paper requires that two special sheets of paper work together. The top sheet of paper is coated with a special dye or ink on the back side. The top of the second sheet of paper is coated with a type of clay that reacts with the dye or ink on the back side of the first sheet of paper. If there are more than two sheets of paper involved in the process, the sheets in between the top and the bottom sheets are coated with both the special clay on the top side of the sheet and the dye or ink on the bottom side of the sheet.

This type of carbonless paper can be used by either someone writing by hand or it can be used by various types of printing machines. If carbonless paper is being used for hand writing, the pressure from the person’s writing instrument will cause the dye to transfer from the top sheet to the bottom or subsequent sheets of paper. If the carbonless paper is being used by some type of printing machine, the pressure from the impact of the striking of the printer head on the paper will cause the ink or dye to transfer from the top sheet to the subsequent sheet or sheets. Carbonless paper can be purchased for these machines in two and three ply rolls of paper.

Naming Your Baby: Beyond the Baby Name Books

Frank Stevens — Tue, 02 Feb 2010 06:05:47 +0000

When I was young, I loved to look through a baby name book that my parents had kept from when they were naming my brother and I. It was a tiny book, similar in size to those “pocket books” you see in line at the supermarket by the cash registers. This book my parents had was especially small in comparison to the behemoth baby name books you find on bookstore shelves today. I loved looking through my parents book and reading all of the names they had underlined as possibilities for their children and imagining how my life might be different if I they had chosen to name me Gwendolyn or Nina.

Today, it seems as if naming a child can be overwhelming with all of the choices and suggestions available out there. As I said, even the baby name books have increased to gargantuan proportions. If you do a simple internet search, you may find hundreds of websites and blogs dedicated to naming a child. On top of that, it seems like names that would fall into the “unique” or “creative” categories are generally more accepted these days, making the number of baby name choices increase exponentially. You can see how a parent would easily get overwhelmed. After reading hundreds and hundreds of names, they all start to sound like gibberish, and who wants to name her child Gibberish?

I say, throw away all of the baby name books and delete all of the bookmarks you have created to the baby naming websites. Your child’s name is as close as your own backyard: your family tree! Family tradition does not have to be limited to dads, granddads, or favorite aunts. Why not look several generations back in your family ancestry and choose a name you like? Think of how wonderful it would be to give your child a family name that has a special meaning to you and your loved ones.

If you or someone in your family has already done some research into your family tree, simply take a look at their notes and make a list of the names that catch your fancy. If you barely know any names past your grandparents, do not fret. Researching your genealogy is not as difficult as it may seem. There are many online resources that can provide you with some sort of family tree making software. And, many of these software choices are free! You could even make a family tree by hand, using pencil and paper. Just remember that you will probably want to share this information at some point and having only a hard copy of your research could create a logistical nightmare.

Once you have a family tree format to enter information into, you can start by filling in the family history that you know just off the top of your head. From there, you can look to many online resources for information on your family ancestry. And again, most of these online resources do not charge a fee for the information they provide. Who knows, you may even get so interested in researching your family tree that you may want to take a course or enter a program on genealogical research that will take your genealogical work to the next level!

Self Service

Frank Stevens — Sat, 30 Jan 2010 08:30:08 +0000

Not too long ago grocery shopping was a full customer service experience. While selecting groceries you had the full service of the butcher or bakery counter while shopping. When your cart was full, the cashier rang up your groceries with a friendly attitude and the bagger carried your bags out and placed them in your car for you. It was generally a pleasant experience. However, grocery shopping is leaning more and more towards the trend of self-service. This is cutting down on their labor costs, but leaving discouraged customers.

Not only do most grocery stores have self checkout lanes installed, but they are not providing cashiers for the regular lanes so a shopper is sometimes forced to use self check-out instead of being checked out by a human being. These self-check out systems use a touch screen display to allow the customer to scan bar codes themselves. Customers are asked to manually identify items such as fruit and vegetables and place them on a device that weighs them. Then weight is then processed into a monetary amount using a price computing scale within the system. After each additional item, the user must place it on the bagging platform so that the weight can match up with what has been scanned or weighed.

In some grocery store chains such as Market Street and Central Market, there have even been price-computing scales installed throughout the store. In these cases, a customer can take the produce, olives or potato salad they want and weigh them on a scale that will convert them into price per pound and print a bar code. Then, at the self-check out lane there is no weighing and manually identifying items needed. The item will already have a barcode and can just be scanned. Some retail chains see this as improving the process of self-check out while also cutting down on labor needed to man the deli counter or prepared foods section.

While this is saving the stores money and ultimately probably cutting down on the product’s price based on less overhead, some customers do not think it is worth it. Studies have shown that it only takes one bad experience to turn a customer into a non-user of self-service checkouts. Customers that are confused and then embarrassed about the machines inability to scan their item will never use it again. There are other kinks that frustrate customers. Such as having to scan every single packet of Kool-Aid so they weight matches. Whereas, the cashier could have just scanned one and told the cash register to multiply it by 20. Coupons and loyalty card discounts are more difficult to handle in the self-service lanes. Also, while the price computing scales inside the machine can convert the weight on the scale into the price designated for the item the customer chooses on the touch screen, the customer still has to choose the correct item. If they choose bananas instead of plantains, they might get charged much less than they should.

Self-service is also starting to work it’s way into pharmacies. Med dispensing kiosks are being implemented in Canada. McDonalds is even trying to roll out a self-service order and pay machine in Europe! Even movies can be checked out in a self-service vending machine now. As each aspect of our lives moves to self-service, it leaves customers wishing for human interaction with cashiers more than ever.

It’s as Good as the Real Thing

Frank Stevens — Sat, 30 Jan 2010 07:55:33 +0000

People are starting to realize more and more every day the importance of a college education. Many working adults who decided to stop school early and have run into a dead-end in their career are looking for ways to further their education in a way that works around their busy schedules. Many companies, understanding the need for educated employees, are offering tuition reimbursement programs for workers that want to go back to school. Working adults are looking for degree programs that will give them the skills to advance. When searching for schools to attend, the question that everybody asks is: Should I go to a traditional school with a campus, or should I attend school online.

As technology has advanced, and the Internet has become a fixture in more American homes, online colleges have become more numerous. Due to the relative newness of this format of learning, many people have a negative perception. Some people will instantly dismiss an online degree, often referring to Internet schools as “diploma mills.” Others simply cannot get past their own personal prejudices, thinking that a “brick and mortar” school is the only way to get a real education. Unfortunately, these are ideas that many people hold. Fortunately, both perceptions are ridiculously wrong. Most online schools offer educational opportunities equal to those of traditional schools, and often work better for non-traditional students.
The “diploma mill” myth is starting to die off as more and more competent professionals successfully advance in the business world right alongside those who went to traditional college campuses. For a long time some people believed that attending online school was equivalent to purchasing a college degree. These people usually had no idea how much work went into completing an online degree program, nor what skills were actually being taught at these schools. Now that online schools have been around for several years, and many people have successfully completed degree programs, the rest of the world is starting to see the value of online schooling. As more people choose this method of study, and more competent professionals use this method to increase their skills, the “diploma mill” stigma will completely fade away.

Many people think that the degree programs at online schools cannot possibly be as rigorous and comprehensive as those at traditional schools. They often think that the standards for these schools are lower than those with physical campuses. This is a very easy myth to dispel. Accreditation is the legitimizing factor for any institution of higher learning. All of the mainstream online schools have the same state and regional accreditations as the traditional schools. The boards that administer these accreditations hold each institution to the same standard, ensuring that the quality of education that the school provides is worthy of recognition. If both schools have to have the same standards to qualify, how can one be better than the other?
Online college degree programs are increasing in popularity. As more people choose this method, the stigma is disappearing. Yes, online college degree programs are as good as the real thing.

Counting Scales

Frank Stevens — Sat, 30 Jan 2010 07:13:25 +0000

Manually counting parts or small items leads to human error. By using special scales designed for counting parts, a company can eliminate this human error and a therefore eliminate some labor cost. These scales called counting scales are used to count small items or parts quickly and efficiently by weight. This scale quickly converts weight information into piece count information and vice versa.

Digital counting scales look at the weight of the items you have placed on the weighing platform and divide the weight by the number of pieces you entered to compute the average piece weight. Usually, the person operating the scales will hand count a sample of the pieces he/she wants to calculate. After zeroing out the unwanted weight for any container, he/she places this sample on the scale and enters the number of pieces in the sample. The scale divides the weight on the scale by the number of pieces on the scale to determine the average piece weight, or APW, of the piece. Then the scale can apply this APW to the total weight and display the count. Just as a scale can be calibrated to weigh in pounds or grams, a counting scale can be calibrated to weigh in units of a specific piece. The items being counted must all have equal weights for the scales to operate correctly. Of course, the more of the items there are, the more accurate the scale can be with its results since it will average out any variations to all the pieces.

Counting scales have different levels of capacity. Some scales can count pieces with tens of pounds of weight and some only have a capacity of a few grams. It is important to not purchase a counting scale with too much capacity than your needs. In order to have a larger capacity, you will be sacrificing resolution. Do not be fooled into getting a larger capacity thinking you “might” need it in the future. If you think there might be a possibility that you will need to be able to count things above the capacity of your counting scale, make sure your scale has a remote scale option. This means you will be able to attach a larger scale to your mechanism for counting items of a heavier weight.

There is some error involved with using counting scales, but certainly less than would be had with manual counting. There can be operator error such as forgetting to zero out the container weight or miscounting the sample. There can be piece weight error. This happens when the operator does not take a large enough sample to average out the variations in weight equally. Piece weight error can also occur when the scale is not level or if a draft or open window affects its accuracy. Some error is from scale related issues. These issues usually have to do with the scales settings. Counting scales can be set to certain resolutions. After millions of counts, a scale will start to not accurately weigh the sample, which throws the entire count off. Setting the scale to tolerate some errors can alleviate this. Usually allowing 2% is a good idea to keep the scale accurate.

Does your Room Sound Funny?

Frank Stevens — Fri, 29 Jan 2010 08:45:51 +0000

Sound is a funny thing. Although it behaves precisely according to well known laws of physics, in practical applications it can be very difficult to predict, much less control. That’s generally because there are too many variables in the equation when it comes to real world acoustics. The walls of the room, the floor covering, the furniture, even the people in the room all affect the way the sound waves behave. By the time music from a loudspeaker reaches the listener’s ear, it has usually been changed by the room to such an extent that there are very noticeable differences, almost always making it worse than it was when it left the speaker.

For home theater rooms, rooms in which people actually listen to music. Or even public spaces where sound quality is important, these room acoustic effects can present a significant problem. Fortunately, there are ways for the average homeowner to substantially remove the room from the audio equation. Acoustic room treatments are used to attack the most common and the most noticeable room acoustic effects.

For home theater systems and music systems capable of delivering deep bass tones, standing waves are often a big problem. Standing waves occur when the sound waves that are created by bass notes are folded or reflected back upon themselves by a room that is smaller than they are in at least one dimension. The sound wave produced by a forty Hertz tone, for example, is fully 50 feet long. This sound wave can be reflected back and forth between the ceiling and floor, front and back walls, or the side walls of the room.

It is helpful to think of sound waves as sine waves with peaks and valleys similar to those of waves on the ocean. When a fifty foot long sound wave is reflected back upon itself, the pressure of the reflected portion is combined with the pressure from the original wave. If the two meeting parts are both above the mid point of the wave, they add up to extra bass. If they are both below the midpoint, then again, the result is extra bass. When one is above the midpoint and the other below, however, they tend to cancel each other out, reducing the amount of bass that can be heard at that particular location.

The net result is that some people in the room hear more bass than was intended in the recording, and some hear less. Almost nobody hears the correct proportion of bass tones in relation to the overall music, unless acoustic room treatments have been applied. The goal of these treatments is to absorb the sound waves before they reflect back into the room from solid surfaces such as the walls. They may consist of single or multiple layers of special acoustic insulation designed to absorb either specific frequencies or broad spectrum sounds. Properly applied, these room treatments can greatly reduce the room effects and let everyone in the room hear the music the way it was intended to be heard.
