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.
We have hybrid devices such as the Itera II which are both PC based and stand alone. It is easy for one to carry out their test session using this instrument. Another hybrid device is the Xeta device ant the other modification is that it is easily portable. They are fast, their flexibility is also great and their efficiency is also very great. The Micro mate audiometer is also hybrid but its uniqueness comes in in the test session that is easy and keeps contact of the patient.
It is very vital to regularly check the audiometers calibration so as to be sure that the level show on the calibration is in line with that of the actual stimulus. The US for instance usually do their calibration of then audiometers acoustically. This is made successful since they have the American Standard Specification for Audiometers that sets the conditions.
If one intends to get their hearing loss, then they have to ensure that accuracy of their calibration is very high so as to get efficient results. If there are complications associated with the calibrations, it is an implication that in case of any treatment, then it will be wrong because of the wrong calibration.
It is thus clear that an audiometer is a clinical instrument but individuals could own them if they are cautious about their hearing loss. There are different audiometers as are listed above. Their calibration is an essential instrument for their performance.
