Pure Tone Audiometry Hearing Loss Hearing Scribd
Pure-tone audiometry is a “gold” standard test of audiologic examination. Its role is to assess whether hearing acuity is normal or impaired. Air conduction hearing thresholds are measured for tonal stimuli at the range of frequencies from 0.125... THE PURPOSE of masking the nontest ear during pure-tone audiometry is, of course, to verify the unmasked thresholds. Studebaker 1 suggested that the nontest ear should be masked during pure-tone air-conduction testing whenever the presentation level at the test ear exceeds the unmasked bone-conduction threshold of the nontest ear by more than

of conventional pure-tone audiometry in hearing screening is an accurate method of hearing screening in developing countries (Berg et al., 2006). Furthermore, Newton et al., (2000) posits huawei gr5 user manual pdf Pure tone audiometry and audiograms Following development of the induction coil in 1849 and audio transducers (telephone) in 1876, a variety of audiometers were invented in United States and overseas.

- MASKING IN PURE TONE AUDIOMETRY Purpose of the test The technique of masking is used in order to isolate the test ear and ensure that results obtained are the true thresholds of the test ear. In pure tone audiometry for both air conduction and bone conduction it is possible that responses obtained are those of the non-test ear. Rationale To establish the true threshold of detectability for air
