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.
Generally it is the computer-based structures that provide the most efficient and accurate of results. These are also more costly than traditional software models. Usually these can be found at audiology centers, research facilities, hospitals and other facilities that put much emphasis on having accurate results.
Audiometers employed on a regular basis for testing should be properly calibrated. This is important to ensure display levels are the same as the stimulus a subject is receiving. The right calibration is essential to getting results that are consistent, no matter where the test is taken. Likewise, the correct measurements are the best way to measure and characterize the type of loss. Most calibration is done through an ACS or Audiometric Calibration Systems, or ESS or Ear Simulator System.
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.
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.
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.
