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 devices may be used in conjunction with bone vibrators. This is typically the case when it comes to evaluating conductive hearing units. There are both hardware and software meters that can be used, each kind comes in many different models. Meters can connect directly with computers and be operated in a home setting for testing purposes. Still, accuracy of such results is not expected to be as good with at-home versions because of the lack of calibration.
In general, clinical devices are produce efficient results that are more accurate. These units are also more costly than traditional software versions. Many times these are used in professional settings, such as audiology centers, research facilities, hospitals and other spaces where precision and accuracy are a major priority.
These devices are employed to test the hearing ability of an individual. Therefore, they should be calibrated on a frequent basis to guarantee that the level that is featured on the display matches the stimulus given to the test subject. Proper calibration is important to producing measurements that are consistent and accurate, regardless of where a test is administered. Furthermore, having measurements that are reliable is crucial when it comes to characterizing the loss. Calibration is usually done through use of an Ear Simulator Systems or ESS, or an Audiometric Calibration System or ACS.
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.
