Audiometry is a graphic recording of hearing quantitatively and qualitatively. Pure tone sounds of different frequencies are produced at different intensity. Pure tones are delivered to ear by head phone for Air Conduction test and by Vibrator for bone conduct test.

The frequency ranges from 250Hz to 8000Hz. And intensity varies from 0 decibel to 120 decibel. The test is performed in a soundproof / sound treated room.

Right ear threshold is recoeded in Red and Left ear in Blue Colour
