Pure Tone Audiometric test

When hearing loss is suspected, pure-tone audiometry may be used to evaluate hearing deficits by spot-checking certain frequencies, or to evaluate deficits more completely.Pure-tone audiometry is performed with the use of an audiometer. Handheld audiometers have a sensitivity of 92 percent and a specificity of 94 percent in detecting sensorineural hearing impairment. There are several types of audiometers available, but all function similarly by allowing the tester to increase and decrease the intensity (loudness, in decibels [dB]) and frequency (pitch, in cycles per second or Hz) of the signal as desired.

Pure-tone audiometry is broadly defined as either screening or threshold search. Screening audiometry presents tones across the speech spectrum (500 to 4,000 Hz) at the upper limits of normal hearing (25 to 30 dB for adults, and 15 to 20 dB for children).Results are recorded as pass, indicating that the patient’s hearing levels are within normal limits, or refer, indicating that hearing loss is possible and a repeat screening test or a threshold search test is recommended.
