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 structures are used along with bone vibrators to check the conductive hearing units. There are meters, software and hardware, available in numerous models. Meters can connect to basic computers and be used at home to test the hearing. However, the results from at-home tests are not considered as reliable and accurate with the models because there is no standard for calibration.
Models that are computer based tend to give the most efficiency with results. The structures are also quite expensive compared to other software. Usually these are applied at audiology centers, research facilities, hospitals and other similar facilities that put much emphasis on having the correct 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.
The word audiometry is taken from words in the Latin language meaning to measure and hear. The definition for this is the ability of a person to hear. The field is mostly focused on hearing capability at certain levels, but there is also science focused on the ability of a person to distinguish between varying pitches, sounds and intensities. These machines may also be used to measure acoustic reflex and Otoacoustic emissions. Results that are from the test may be used by doctors for diagnosis.
These meters are sold from retailers around the world. Unsurprisingly, the prices will vary dependent on the type. Models that offer the top accuracy cost more and are often used at professional facilities because of this. There are also models made specifically 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.
Machines that are used in the audiometry field are known as audiometers. These devices, which are available in many different models, are employed to measure the type and amount of hearing loss. The complex models tend to produce the most accurate of results and are usually employed at professional facilities. There are also at-home devices that are less expensive and available at many stores. These, however, do not provide the same amount of accuracy. Calibration is essential for all such devices because it effects the results. Hearing loss is sometimes total or partial, temporary or permanent, and can be caused by a variety of things.
