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.
On the other hand, bone conduction hearing is tested using an artificial mastoid. Such device calibrates the bond conduction channels of audiometers. Bone conduction mechanisms can be used to test hearing. This device has a dome shaped part which emulates a human mastoid. The force applied is measured by a force transducer. A sound meter also measures the output.
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.
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 know the importance of having audiometers in their facilities. Physicians must have the kind of equipment needed for them to perform their duties. Proper equipments are necessary to they can provide quality treatments and better services. Patients can be given appropriate management if they are accurately diagnosed. This gives them a better chance at recovery.
