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.

With the clinical computer-based devices that are used, results are usually more accurate. In fact, these are often what is employed at professional places, including hospitals, research facilities and audiology centers, places where accuracy of results and precision is important. These tend to be more costly than the usual software models.

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.

A lot of retailers have these meters available for sale at different costs. Those that are more complex tend to offer the best results and are usually more expensive. These are what is used in most professional environments. Still, there are at-home versions available.

Hearing loss may be caused by numerous things. Loss may be considered partial or total, and permanent or temporary. Usually the amount of hearing loss is best determined by assessing the increase in volume that is needed for the subject to detect the sound. This is an issue of decreased sensitivity to sounds normally heard.

When it comes to these devices, the most important thing is calibration. There are numerous makes and models of this meter that can be used, even those designed specifically for use at home. The highest accuracy is expected from units used in professional settings. However, proper calibration can ensure consistent and accurate results from nearly any device. There are many people who suffer with hearing loss, which can be temporary or permanent, and total or partial.
