The Main Components Of Audiometers

By Lana Bray


Audiometers is the name given to the structures that are used for the purpose of evaluating the amount of hearing loss in a person. These units are mostly used at professional health facilities, such as audiology facilities or ear, nose and throat offices. Typically they include embedded hardware that has been connected to headphones. There is also a test button that can be controlled through nearly any basic computer device.

When paired with bone vibrators, these units are used to test conductive hearing devices. There are software and hardware meters that can be applied, each available in an assortment of models. Meters are usually connected to and operated through computing devices. There are even at-home models that can be used, although their accuracy is lower because of the absence of a calibration standard.

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 retailers have these products available in stock. The cost of such machines will range. The complex versions offer high accuracy results and are often more costly than traditional models. This is why they are primarily for professional use. There are also inexpensive versions available for use in the home.

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.
