What is an audiometry ?

Audiometry is the testing of hearing ability. Audiometry determines a person’s hearing levels with the help of an Audiometer at different sound intensities and pitch, typically from 0 to 120dB and from 250Hz to 8000Hz.

The most commonly used assessment of hearing is the determination of the threshold of audibility, i.e. the level of sound that is just audible at different frequencies. The audiometric test can be carried out using automatic or manual audiometers in a sound-proof room to eliminate external sounds from influencing the test. The results for both ears are often plotted graphically on an Audiogram.

This quantitative assessment of a person’s hearing ability helps the audiologists to diagnose severity and type of hearing loss.
