An audiometer is an instrument used to measure the hearing loss of an individual. The hearing loss of an individual needs to be determined in order for one to receive the right type of medication for their problem. These devices consist of a hardware that could be connected to headphones and are usually under the control of a standard PC. There are software devices as well as hardware 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.
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 important that the calibration of an instrument be done regularly so as to confirm that the level show on the display is the same as the real stimulus exposed to the subject. Countries such as the US check calibration of audiometers acoustically . This is done in line with the conditions set by the American Standards Specification for Audiometers.
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.
