The machines that are used to test hearing loss are called audiometers. The devices are typically used as ear, nose, throat facilities, and audiology doctor offices. Typically these include embedded hardware connected to headphones, as well as a test button that is controllable through basic personal computers.
Sometimes the devices are used in conjunction with bone vibrators as a way to check conductive hearing systems. Hardware and software meters are also included and come in a variety of models. Meters attach to personal computers and can be operated from home for hearing tests. Still, results from these tests are usually not as accurate or reliable because there is no standard when it comes to 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.
The audiometers used regularly for testing hearing should be calibrated often to guarantee that they levels on the display are equivalent to the stimulus that the subject is being exposed to. Proper calibration is important when it comes to producing measurements that are consistent, regardless of where, or on what, the test is done. Furthermore, the right measurements are important for quantifying or characterizing the loss. Usually calibration is handled by use of ESS, Ear Simulator System or ACS, Audiometric Calibration System.
Audiometry is the term that is derived from two Latin words, one meaning measure and the other to hear. This word is defined as the ability to hear. This field is primarily focused on the ability to hear at specific levels, but there is science related to the ability an individual has to distinguish between various intensities, pitches and sounds. Machines can also be applied to measure Otoacoustic emissions and acoustic reflex. The results taken from these tests are utilized by doctors for diagnostic reasons.
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.
Hearing loss can be caused by various things. It may be total or partial inability. The main problem is lowered sensitivity to sounds typically heard. Usually the amount of loss is determined based on the level of volume that must be increased before sound can be heard.
Audiometers are structures that are used in the field known as audiometry. The machines, which come in various models, are applied to measure the kind and quantity of hearing loss. The models that are complex usually bring the best results are employed at professional places. Devices used for at home are available from several different stores. These do not usually produce the best accuracy in terms of results. Calibration is important for these devices and impacts the final results. Hearing loss can be the result of many different things and may be temporary or permanent, partial or total.
