The Use Of Audiometers In Diagnostics

By Roxanne Cruz


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.

This field has had many developments over the years resulting in different variations of these devices. One type is referred to as clinical PC based which is more accurate when used to test hearing loss. These are the types often used diagnostic centers, hospitals, and research studies. A screening PC based is also available and this can be used at home for personal hearing tests.

These equipments must be calibrated routinely to make sure that levels on display are equal to the stimulus the patient is subjected to. Proper calibration ensures that measurements are always consistent and results are accurate. The devices are calibrated using audiometric calibration system. When it comes to diagnostic tools, accuracy is very important.

Air conduction hearing will be tested using a system with an ear simulator. In this system, air conduction is calibrated using an artificial ear. The headphones will be connected with the open side of the coupler. An internal microphone is used to detect sound pressure level on the inside of the cavity. A sound level meter will also measure the outputs.

Bone conduction hearing can be tested with an artificial mastoid. The device can calibrate bone conduction channel of audiometers. This is used to test hearing as response to bone conduction mechanisms. The tool has a dome which represents the human mastoid. A transducer measures the force applied and the output is measured by a sound meter.

Different models of the devices are now available. Each of these models may have its own specifications making them suitable for specific purposes. Using these devices, physicians can efficiently diagnose hearing loss and related problems. Diagnostic procedures would require the use of special equipments. These devices have made such a difference in this field.

With different types available today, hearing specialists can find an equipment that can be of best use to them. Some of these are stand alone equipments which are used for screening purposes. There are also a number of units that are computer based used for diagnostic examinations. These equipments can have different frequencies and intensities depending on their exact purpose.

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 already know the significance of audiometers in their field. Physicians should have appropriate equipment in their clinics in order for them to do their job correctly. They must have the right equipment to provide quality services and better treatment to patients. A hearing condition can be managed effectively if the patient is correctly diagnosed.
