![]() Testing involves ascending in 5-dB increments until patient gets 50% responses correct, then descending 10 dB and ascending in 5 dB again.Test to within 5 dB (to account for test–retest variability).Subjectively better-hearing ear tested first.Test order of frequencies 1, 2, 4, 8 kHz then 500 and 250 Hz repeat 1 kHz again to check within 5 dB of first result.Soundproofed facilities needed for definitive/diagnostic testing.A vibrating tuning fork is placed on the midline of the skull.Ī Equal loudness perceived in both ears means symmetrical hearing.ī Lateralization of sound to the affected ear (right) is present in the case of conductive hearing loss.Ĭ In cases of sensorineural hearing loss, the sound is lateralized to the better ear (left).ĭ Correct orientation of the tuning fork. ![]()
