QUANTIFYING SOUNDS

Audio test equipment is used to measure the sound quality produced by a device or machine. Usually audio test equipment is calibrated to a certain standards and used to see if the machine being tested meets those sound parameters.

Audio test equipment is very important especially when the machine being tested produces sounds that are strong enough to be harmful to humans. This is true with aircrafts and industrial instruments.

By using the audio test equipment, you can check if the sounds generated exceed the allowable value. Usually there is a threshold that machines must not go beyond. If the machine does go beyond the threshold as determined by the audio test equipment, then the machine has to be redesigned. The process goes on until the mechanism meets the health standards.

THRESHOLD VALUES

Test equipments can be very expensive. If you cannot afford buying one for your company, there are test equipment rental companies that you can go to. However, if you are in the business that makes use of test equipment on a regular and frequent basis, you will be better off buying one. While test equipment rental is substantially lower than buying, in this case you may end up saving more if you purchase your own.

There are many types of test equipment aside from audio test equipment. Each designed to measure a particular parameter. Vibration test equipment is yet another common type. Vibration test equipment determines how much movement a device can take before it gets broken. Gadget such as watches and cellphones are tested for this to rate their resistance to shock and vibration.

Test equipment is valuable because it sets clearly defined lines that must not be crossed. Its main value is in helping us determine the quality of the things that we are buying. By purchasing items that meet testing standards, we are assured that what we are buying is safe and durable.
