Audiometers are devices used to evaluate hearing loss. These are standard equipments found in audiology centers. Such devices typically consist of hardware connected to a pair of headphones and a button for the test subject. With advances in technology today, some of these devices are controlled by computers. There are certain standards set for the test 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 their important function, the devices should be calibrated routinely. This is necessary to make sure the levels on the display are always equivalent to the stimulus that the patient is exposed to. With proper calibration, the measurements will be consistent and the results will be accurate. An audiometric calibration system used to do the calibration.
For testing air conduction hearing, an ear simulator is included in the system. In this system, the artificial ear is designed to calibrate air conduction. The headphones are applied to the coupler's open side. An internal microphone will detect the sound pressure level inside the cavity. The electrical output is measured using a sound level meter.
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 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.
