There are numerous things that can be used today to test the function of different body parts. When it comes to the ears and hearing, audiometers are employed. These small devices are often used at the offices of ear, nose and throat physicians, and audiology facilities. They are made with embedded hardware that attaches to headphones and a test button that can be controlled through most personal computers. The primary function of the devices is to check the hearing ability of a test subject.
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.
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.
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 sold through many retailers. Prices will differ depending on the type. Models that offer better results are usually more complex and therefore more costly. These are usually only seen in professional settings. There are also versions designed for at-home use.
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.
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.
