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.
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.
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.
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 must be fully operational and efficient all the time. Accuracy is one important factor that these devices must have in order to provide reliable measurements. Results must be accurate to establish proper diagnosis of one's hearing loss. Specialists need to determine the extent of hearing damage so they can also recommend appropriate management.
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.
