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 a word that derives from the Latin language. It is a combination of words that mean to measure and to hear. It is generally defined as measuring of hearing ability. The field is centered on checking hearing ability at varying levels and tracking the ability of an individual to distinguish sounds, intensities and pitches. The machines used in the field are able to measure otoacoustic emissions and acoustic reflex. Results from tests help physicians when it comes to diagnosing problems of the ear, whether it is hearing loss or something other.

A lot of retailers sell these items. Prices for the products will differ. Complex models that provide results with high accuracy are often more expensive and used in professional environments. There are inexpensive models that can be purchased for use at home.

Many different things can lead to hearing loss. This loss might be partial or total. The key problem is a decreased sensitivity to noises typically heard. Usually the amount of loss is based on the increase that is needed for the sound to be picked up by the hearer.

Audiometers are units used primarily in the field of audiometry. These devices, which come in numerous models, are used when trying to measure the amount of hearing loss. Complex versions tend to have the highest amount of accuracy for results and often used in professional places. At-home models are less costly and available via numerous retailers. These do not always provide results that are as accurate as the more complex types. In either case, calibration is important when it comes to correctly operating these devices.
