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.
There is a software device called the Screening PC Based hearing loss measurement device. It is controlled by the standard computer. This type of instrument can usually be purchased by any person with the aim of checking their hearing loss. Their disadvantage is that their accuracy is poor as they do not have a standard for calibration. Some among this type can be found on hand driven devices that are 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.
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.
Itera II hearing sensors are hybrid audiometers meaning that they have both PC and stand alone system, that carry out the entire diagnostic testing process. It is also preferred because it is somewhat simple to the test session. The Xeta hearing sensors are also hybrid and are portable. Many people term them as fast, flexible and efficient. The last one is the Micro mate hearing sensor that is stand alone as well as PC based. It is easy for the test session and also to keep contact with a 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.
