The hearing loss of an individual could be determined by an audiometer. The problem of hearing loss could only be solved if the individual's hearing loss has been determined. Hearing devices have a hardware that is usually put together with a headphone and they fall under the control of a standard PC. We have two types of devices, software devices and hardware devices.
An example of the software AM is the Screening PC Based AM that only uses a standard computer. This can be owned and run by anyone in their homes to check their hearing. Their accuracy however is not very good because they lack a standard for calibration. Some of these screening PC based devices can be found on a hand held device that is windows driven.
The Clinical PC Based hearing loss measurement instrument is also an example and is sufficiently expensive compared to the Screening PC Based hearing failure recording device, which clearly is a software hearing device. The portray themselves as sufficiently accurate and efficient as compared to the software devices. They are useful to the professionals in hospitals, audiometric centres and also research centres. Hardware devices are less accurate than this type of devices.
The market offers a variety of hearing sensors each with their own unique modification. These include the Astera hearing sensor that is clinical. This type of hearing sensor is PC based. Another one is the Aurical hearing sensor that are also PC based. It is very accurate with the clinical process and uses batteries. There are also Midimate hearing sensor that are stand alone meaning they are not PC based. It s uses air, bone and speech for the audiometric process.
The other one is the Itera II devices. They are hybrid which means that they are bot PC based and stand alone. The whole diagnostic process is done by these machines. Using it in the test session is very simple. The Xeta devices are a different type that have easy portability and are hybrid too. They are referred to as fast, flexible and efficient. Micro mate device is another type that is hybrid and simple for then test to be done and helps the patient to keep in contact.
The devices calibration should be checked time after time so as to ensure that the stimulus level is the same as that shown on the display. Acoustical checking of the audiometer is mainly practised by countries as the US. The American Standards Specification for Audiometers is the one that sets the method to be used in dong this.
For one to quantify their hearing loss, the audiometer they are using have to be very accurate for it to produce reliable measurements. If the device has complications with its calibration, it means that the measurements found are wrong and therefore the frequency set for the correction would be wrong.
To conclude, we have seen that an audiometer is an instrument of medical check up that could be used both in hospitals or domestically by anyone who needs to check their hearing loss. A variety of audiometers are available just as stated above. One of then most essential things about the audiometers is their calibration.
