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.
There rare different types of hearing devices with different modifications in the market. The clinical Astera one is an example and it is PC based. The PC based Auricle one is another example. It uses batteries I its operation and has proved to be extra accurate. We also have the Midimate audiometers that are stand alone in other words they are not PC based. The audiometric process uses air, bone and speech.
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.
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.
