The Main Components Of Audiometers

By Essie Osborn


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.

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 integral when it comes to properly using these machines. There are many makes and models available, including at-home kinds. The most accurate results are expected from the versions used in professional settings. Nonetheless, proper calibration can ensure consistency and accuracy from most meters. There are a lot of people suffering with some degree or type of hearing loss.
