The audiometer is a machine created to evaluate the hearing loss. This type of equipment is in general used in specialized clinics and audiology centers. In general the audiometer equipment consists of a hardware unit, a pair of headphones and a button to be used by the subject to give feedback. In order to be recognized as equipment, an audiometer has to follow the ISO 8253, IEC60645 and ANSI S3.6 standards.
There is a large variety of audiometer equipments available now on the market. Screening audiometers can be portable, are not weighting too much and are operating on batteries. Equipments used in specialized audiology clinics are usually heavier, compatible with PC, and the information they provide is highly accurate. The PC audiometer is easy to use, practical, and can include air and bone conduction tests.
Hospitals, research communities and specialized audiology centers are usually using clinical audiometers. But the software audiometers are becoming more popular, because are coming with almost same features and are very easy to use. Almost anyone can use these equipments if in possession of a PC and a windows driver. In what regards the cost, these are more accessible than the clinical equipment, but as calibration standards are not available, their accuracy is not the maximum.
In order to assure a maximum accuracy, these type of equipments need to be calibrated regularly. Calibration is a procedure that assures that the levels measured and displayed are according with the reality. When these equipments are calibrated correctly, even the smallest hearing problem can be identified, and no matter the place where the measurement is performed, the results are all the same.
In general, for the calibration of these hearing loss detection equipments, an audiometric calibration system is used. This is based on a calibrated microphone that is linked to a coupling volume, opened at one side. For mechanisms that are testing the bone conduction hearing, a mechanical coupler is needed. This device will mimic the sound that is produced through the mastoid section of the temporal bone.
Like any other machines, the parts of these equipments are liable to drift after a period of use. In order to assure a high level of accuracy, these hearing measurement equipments have to be calibrated in proper conditions. Only specialists have the ability to perform this sensitive procedure. It is also important that the measurements are made only in specialized laboratories.
The evolution of technology can now assure that these machines are offering a high accuracy of measurements. Many of available models can be very efficient to identify and measure hearing problems at home. In order to fulfill market requirements, manufacturers are now producing audiometers with color touch screen, multiple languages, large storage capacities and multiple users interface. Information can now be backed up and synchronized with computers.
A hearing loss problem can be identified in early stages with the use of the right equipment. Therefore a first check should be made only in specialized audiology clinics, with equipments that are offering accurate measurements. After being diagnosed correctly, the evolution during treatment can be monitored at home with the help of software audiometers.
