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.
Clinical PC Based devices are the next examples, and they are comparatively more expensive than the Screening PC Based hearing devices, a software based device. Their efficiency is much better that that of the software device that we know of. They are used in hospitals, research centres and audiometric centres by the professional doctors. The accuracy of their calibrators is also good compared to the hardware 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 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.
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.
