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.
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.
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 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.
