General Information To Know On Audiometers

By Essie Osborn


There are special devices used to check the level of hearing loss a person has. These are known as audiometers and are often used at audiology facilities, as well as throat, nose and ear offices. Typically these include embedded hardware that has been attached to headphones. There is also a test button that can be used on most standard computers.

The units are sometimes used along with bone vibrators. This is often done to evaluate conductive hearing units. There are software and hardware meters made available, each that come in a range of models. The meters are designed to directly connect with computers and can be operated from a home to test hearing. However, the accuracy of results is not expected to be as high with at-home models because there is no standard set for calibration.

Generally speaking, the clinical devices are known to produce the most accurate of results. These are also more expensive than most traditional software kinds. Often they are employed in professional places, such as research facilities, hospitals, audiology centers and other places in which accuracy and precision of results is the ultimate priority.

The units are mostly used to test the ability of a person to hear. It is important that these are calibrated correctly on a frequent basis to ensure the level that is on a display matches that which is given to the test subject. Proper calibration guarantees measurements that are consistent and correct, regardless of where a test is taken. Furthermore, the results of these tests are important because they are often used to classify the amount and type of loss. Audiometric Calibration Systems and Ear Simulator Systems are usually used to calibrate the devices.

Audiometry is a term derived from Latin. Generally it is defined as measuring the ability of one to hear. This field is focused on checking hearing ability at varying levels. Still, the science involved also tracks ability of one to distinguish between various sounds, intensities and pitches. These devices can measure Otoacoustic emissions and even acoustic reflex. The results from tests are beneficial to physicians during the diagnostic process.

Meters are available for purchase through many retailers. These will come at different prices. Generally, the more accurate and complex the device, the more costly it will be to purchase. These types are usually what is employed in professional places. But there are also at-home kinds available too.

A lot of things may contribute to loss of hearing. This is often categorized as total or partial, and temporary or permanent. Regardless, the problem is associated with a decrease of sensitivity to sounds that are typically heard. The degree in loss is usually determined by look at the increase of volume that is necessary before sound can be detected.

Calibration is the most important thing related to these devices. Many models and makes are available, even versions for use at home. The highest level of accuracy is expected from those used at professional facilities. Still, the right calibration can guarantee accurate and consistent results from nearly any meter. There are many who suffer with loss, which might be total, partial, permanent or temporary.
