Web3 de dic. de 2014 · A four-frequency pure tone average (PTA) of hearing thresholds obtained at 0.5, 1.0, 2.0, and 4kHz was calculated for the better ear. Mild hearing impairment was defined as a PTA >25 and ≤40 dB HL, and moderate or greater hearing impairment was defined as a PTA >40 dB HL per World Health Organization definitions . … WebPreoperative Measures. PTA was performed using frequencies of 0.5, 1, 2, and 4 kHz to calculate the preoperative degree of HL. In addition, speech understanding scores were conducted using the standard Dutch SPT of the Dutch Society of Audiology, which comprises phonetically balanced monosyllabic consonant-vowel-consonant words …

WebPure-tone audiometry. 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 kHz to 8 kHz with the use of headphones.
