Instruments used to determine the hearing capability of persons is called an audiometer. Determination of the hearing capability of a person is essential so that one may get the right medication. These instruments are usually under the control of a standard PC and one of their components is a hardware that can be connected to headphones. We have both software hearing devices and the hardware based ones.
One of the software hearing measurement device is the Screening PC Based instrument, which uses a standard computer only. Any person at their homes could check their hearing through this. They are however not accurate enough since they do not have a standard calibration. Some screening PC based devices could be found on a windows driven hand device.
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.
There is a variety of hearing instruments offered by the market, each unique in its own way. One of them is the Astera instrument, which is a clinical one. It is PC based. Another PC based one is then Aurical hearing devices. In its clinical process, it is actually accurate and is run by batteries as well. The mid mate hearing device are not PC based but are stand alone devices. Air, bone and speech are the main features used in 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.
It is important that the calibration of an instrument be done regularly so as to confirm that the level show on the display is the same as the real stimulus exposed to the subject. Countries such as the US check calibration of audiometers acoustically . This is done in line with the conditions set by the American Standards Specification for Audiometers.
Accuracy of then calibration of a device is then most essential measure for one to consider if they want accurate audiometer results. Had the calibration of the audiometer been having complications, then then individual would have then absolutely wrong frequency as a corrective measure.
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.
