Audiometers are equipments used to evaluate or diagnose hearing loss. These devices are typically used in audiology centers. The equipment is made of hardware which is connected to headphones and one button that is for the subject. With advanced technology today, computers are used to control these devices. There are also standards for these procedures.
As this field has developed over the years, different variations of the devices have been made. One type of the device is clinical PC based. These are more accurate when testing hearing problems. These types are generally used in hospitals, diagnostic centers, and research studies. Another type is the screening PC based which can be used by anyone in their own homes to test hearing.
With such important functions, these devices need to be routinely calibrated. This will ensure that the levels displayed are equivalent to the amount of stimulus applied to the subject. Proper calibration will ensure consistency of measurements and accuracy of results. Accuracy is important for any diagnostic tool. Calibration can be done with the use of audiometric calibration system.
To test air conduction hearing, a system that includes an ear simulator is used. For this system, an artificial ear calibrates air conduction. Headphones will be applied to the open side of the coupler. There is an internal microphone that detects sound pressure level within the cavity. Outputs will be measured by a sound level meter.
Meanwhile, bone conduction hearing will be tested with the use of an artificial mastoid. This device can calibrate channels of bone conduction in audiometers. This can test hearing in response to mechanisms by bone conduction. It has a dome that is similar to the human mastoid. In this case, the force applied will be measured by a transducer and the output will be measured with a sound meter.
Several models of these devices now exist. Different models have their own specifications and these can be used for specific purposes. With these devices, hearing problems can be effectively diagnosed by physicians. Diagnostic procedures simply cannot be performed without the use of certain equipments. It is easy to see how these devices made a big difference in the field.
Since there are already many equipments available, hearing specialists can choose an equipment of their choice. Some types are the stand alone kind and these are usually used for screening. The computer based types are often used for diagnostic purposes. These devices have their own frequencies and intensities which may depend on the exact application they are for.
Diagnostic equipments should be efficient and fully operational all the time. One important factor that must be possessed by these equipments is accuracy. This factor ensures the users that measurements are reliable. The results should be accurate as much as possible to make a correct diagnosis. Specialists must determine how extensive a patient's hearing loss is to provide effective treatment.
Hearing specialists realize the need to have audiometers in their clinics. It is very important for physicians to have the right type of equipment. This is essential for them to provide quality treatment and services to patients. With proper diagnosis, patients can be treated effectively so they can be relieved from their symptoms and have better chances at full recovery.
