Special devices are used in the modern day in order to check hearings loss. These units are called audiometers and they are often seen at audiology offices and the facilities of ear, nose and throat doctors. They feature embedded hardware that connects to headphones, as well as a test button that is used for control purposes and can be operated through most computers.
These are sometimes used with bone vibrators to assess conductive hearing units. There are software and hardware meters available, as well as the many models that fit under those categories. Meters are designed to be able to attach to computers directly ad can be used from home. However, the accuracy level of at-home test results is not usually as high because there is no standard 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.
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.
Meters are available for purchase through many retailers. These will come at different prices. Generally, the more accurate and complex the device, the more costly it will be to purchase. These types are usually what is employed in professional places. But there are also at-home kinds available too.
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.
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.
