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.
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.
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.
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.
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.
Various models of these equipments are now used. These models have certain specifications that make them suited for specific applications. Now that these equipments are available, it is easier for physicians to diagnose hearing problems. Special equipments would be needed to perform some diagnostic procedures. This field in medicine has greatly benefited from these tools.
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 realize the need to have audiometers in their clinics. It is very important for physicians to have the right type of equipment. This is essential for them to provide quality treatment and services to patients. With proper diagnosis, patients can be treated effectively so they can be relieved from their symptoms and have better chances at full recovery.
