General Information To Know About Audiometers

By Alyssa Riggs


The structures that are used when evaluating hearing loss in an individual are called audiometers. These machines are typically found at ear, nose or throat office, or audiology centers. Typically embedded hardware is present and connected to headphones. There is also a test button that is controlled through a personal computer.

In some cases, the devices are applied with bone vibrators. This is done for checking conductive hearing systems. Software and hardware meters are usually included and come in an assortment of types. Meters are connected to personal computers by which they are controlled. The results of most home screening tests are typically not as reliable or accurate because there is no standard in terms of calibration.

The computer-based models are those that provide the most accurate and efficient results. Said structures are also more expensive than the traditional software devices. Typically these are used at research facilities, hospitals, audiology centers and other similar places that require accurate results.

Audiometers that are used consistently must be checked for proper calibration. It is crucial that the display levels match the stimulus being sent to the test subject. The proper calibration is important for getting accurate results that remain consistent, regardless of where or how the test is administered. Furthermore, these measurements are the best way to classify and quantify the loss. Audiometric Calibration System or Ear Simulator System may be used to calibrate.

Audiometry is taken from the Latin language, two words meaning hear and to measure. It is defined as the ability of one to hear. This specific field relates to ability to hear at certain levels, but the science that is involved includes recording the ability of one to distinguish between various intensities, pitches and sounds. The structures can measure Otoacoustic emissions and acoustic reflex too. Results from the test can be used by doctors to diagnose many problems not related to hearing loss.

A lot of retailers sell these types of meters. Prices for the devices will range based on the kind. Models known to offer more precise results typically cost more money and are usually employed only in professional settings. There are also types made for use at home.

Many different things can contribute to the loss of hearing. Sometimes this is partial and other time it is total. The main issue is a low sensitivity to sounds normally heard. The loss is quantified based on the level at which the sound must be increased before the test subject can hear it.

Audiometers is the name given tot he structures that are used in audiometry. These machines come in an assortment of models and are used to measure the amount and type of hearing loss. The complex versions are usually found at professional places because they offer the best results. There are at-home devices available for sale via numerous stores. Still, these are not known to produce the best results. Calibration is key when it comes to the devices. Hearing loss may be temporary, total, partial or permanent, and can be caused by a variety of factors.
