142.9.4 Pure Tone Audiometry Pure tones of variable intensity and frequency are delivered to the ear by a headphone placed in the ear (air conduction) or on the mastoid (bone conduction). The patient signals whenever he or she hears a sound. It is important to use noise to mask the be...
What is audiometry ●Threshold Measures●Pure Tone:○Air & Bone●Speech●Behavioral Testing Threshold least amount of sound necessary for a signal to be detected 50% of the time Pure tone -single frequency tone-250-8000 Hz Air conduction what frequencies do we test it at? 250-8000 Hz Bone...

(i) In the case of Class 1 medical certificates and Class 2 medical certificates, when an instrument rating is to be added to the licence held, hearing shall be tested with pure tone audiometry at the initial examination and, at subsequent revalidation or renewal examinations, every 5 years ...
Abstract:The objective was to evaluate the pure-tone audiogram-based screening protocols in VS diagnostics. We retrospectively analyzed presenting symptoms, pure tone audiometry and MRI finding from 246 VS patients and 442 controls were collected to test screening protocols (AAO-HNS, AMCLASS-A/B, ...
Paired t-tests, correlation tests (Pearson's r, Cronbach's alpha, intraclass correlation) and absolute differences were used to examine the relationships among pure tone audiometric (PTA) frequencies for all ears with hearing loss. 168 ears were found to have OME-related hearing loss. Only the...
When the difference in hearing between the two ears is of some considerable degree, it is essential to block the betterhearing ear by a masking device, for accurate estimation of the threshold of hearing of the bad ear. In air conduction tests, when the difference in thresholds of the two ...
In this report, we evaluate the correlation between air conduction pure tone thresholds produced from a mobile hearing application as compared to the results from formal audiometry in a general population of adult patients with auditory complaints. ...
By using pure tone averages (PTAv), mean hearing level (MHL) and mean gap (MG) were calculated. RESULTS: PTA was achieved in 90% of the children and PTAv of bone and air conduction in the both ears were obtained in 86% (play audiometry with earphones (PAE): 73%, conventional audio...
