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.
Derived from Latin, audiometry is a term defined as measuring ability of a person to hear. This field is mostly centered on evaluating the ability to hear at different levels. Nonetheless, the science behind it also involves tracking ability to distinguish between varying pitches, intensities and sounds. These machines are also capable of measuring acoustic reflex and Otoacoustic emissions. The results from tests can be helpful during the diagnostic period.
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.
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.
