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.
To test air conduction hearing, a system that includes an ear simulator is used. For this system, an artificial ear calibrates air conduction. Headphones will be applied to the open side of the coupler. There is an internal microphone that detects sound pressure level within the cavity. Outputs will be measured by a sound level meter.
Meanwhile, bone conduction hearing will be tested with the use of an artificial mastoid. This device can calibrate channels of bone conduction in audiometers. This can test hearing in response to mechanisms by bone conduction. It has a dome that is similar to the human mastoid. In this case, the force applied will be measured by a transducer and the output will be measured with 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.
Since various types are now available, hearing specialists will be able to find their choice of equipment. There are stand alone types which are often used for screening. Some are also computer based which are commonly used for diagnostic purposes. Each of these equipments have different intensities and frequencies depending on the exact application these are designed for.
Diagnostic equipments should always be fully functional and working efficiently. Accuracy is a very important quality of these devices to make sure they provide reliable measurements. Accurate results are necessary to create a correct diagnosis of one's hearing problems. Specialists would need to know the extent of the patient's hearing loss to determine what type of management would be effective.
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.
