The Main Components Of Audiometers

By Lana Bray


Audiometers are structures used to test hearing loss. These are typically found at professional facilities, such as ear, nose and throat facilities, as well as audiology offices. Most include embedded hardware that connects to headphones and the test button operated through a computer.

The machines are also used with bone vibrators as a way to check conductive hearing devices. There are both hardware and software meters that can be used and come in different models. Meters typically connect to basic computers and are operated through them. There are even versions for use at home. Still, the accuracy of these home-kit results is less on point because there is no set standard for calibration.

The clinical devices are usually more on point and produce efficient results. They are also more costly than the traditional models. For this reason, they are general used in professional settings, such as hospitals, audiology centers, research facilities and other such businesses where precise and accurate results are a main priority.

Devices that are used often should be calibrated on a frequent basis. This is important to ensure that the display says the same as the stimulus that the test subject is exposed to. Additionally, the correct calibration is essential to getting consistent measurements that are the same regardless of where tests are done. Reliable measurements are necessary to help quantify and characterize loss. ACS or Audiometric Calibration System and ESS or Ear Simulator System are machines typically employed when calibrating these devices.

Audiometry is derived from Latin words meaning to hear and to measure. This practice is often defined as measuring of hearing ability. The field is primarily concerned with checking hearing ability and different levels and checking the ability of one to distinguish between varying sounds, pitches and intensities. These devices are also used for otoacoustic emissions and acoustic reflex purposes. The results of tests are used by doctors to diagnose all types of ear problems.

Many different retailers sell these products. The prices for these will vary. Models that are more complex and offer highly accurate results are typically more costly and used in professional places. There are also less expensive, at-home models available.

There are so many things that contribute to hearing loss. This may be total or partial. The main issue is lowered sensitivity to noise that is often heard. Typically loss amount is measured by the amount of increase necessary before sound can be heard.

Audiometers are devices employed in audiometry. These units, which are available in different models, measure the amount of hearing loss. Complex models tend to provide the highest accuracy with results and are typically used in professional environments. There are also at-home versions that are less expensive and available through many retailers. Calibration is essential when it comes to proper operation of these devices.
