Audiometers are tools primarily used to evaluate hearing problems. These equipments are commonly found in audiology clinics. These devices usually consist of hardware that is connected to a set of headphones. There is also a button intended for the subject. Now that technology is advanced, these devices can be operated with computers. Standards are set for these test 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.
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.
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.
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 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.
