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 next example is the Clinical PC Based devices which are quite expensive compared to the Screening PC Based devices, which is a software device. This type of device are way more accurate and efficient than the other software devices. These devices are mainly used by professionals in hospitals, research communities and also audiometric centres. Their calibrations is also way better and accurate than hardware 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.
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.
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.
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.
In conclusion, audiometers are instruments used by professionals in say hospitals, but there are others that could be used domestically by people who would like to observe their hearing loss. Different audiometers are in existence as clearly listed. Their performance is determined mainly by the accuracy of their calibration.
