Pure-tone audiometry is a subjective, behavioural measurement of a hearing threshold, as it relies on patient responses to pure tone stimuli. Therefore, pure-tone audiometry is only used on adults and children old What to expect: This little demo is not too unlike the standard audiometric test known as a pure-tone audiogram. We present pure tones of different frequencies at different sound levels, and adjust their level until they become inaudible in order to measure the "threshold". PURE TONE AUDIOMETER It is the electronic device used for creating pure tone audiogram. It consists of an audio-oscillator which generates pure tone sounds of different frequencies. Each tone can be separately amplified to a maximum of 100 to 110 dB in most frequencies except very low & very high frequencies.
