Workers having a minimum of 5 years of noise exposure were included whereas workers having age >45 years or with conductive hearing loss that is, air-bone gap >10 dB were excluded from the study. Results: It was found that factory workers showed normal hearing, when calculated as average of 500 Hz, 1000 Hz, 2000 Hz, and 4000 Hz but they have started developing the early changes of NIHL in the form of …

(2005) demonstrated this in a longitudinal study by analyzing pure-tone thresholds for standard and extended high-frequency audiometry in 188 older adults. 2020-02-24 Usually as we age we lose the higher frequency first, the 20 khz range, usually 15khz or so.

While this localization ability has been found to be reduced in listeners with a hearing loss in the typically measured frequency range of 250 to 8000 kHz, less is

How Sound is Measured The detrimental effects of hearing loss on speech perception are well known, and a primary goal of clinical audiology is to restore the audibility of speech cues between 125 Hz and 4 to 8 kHz. Hearing loss at extended high frequencies (EHF; above 8 kHz) is common in adults 30 years of age and older, 1, 2 but it usually goes undiagnosed because EHF audiometry is typically not part of the routine audiological exam. The prevailing view is that EHFs are not critical to daily listening. Induced hearing loss is currently detected and moni-tored with pure- tone audiometry. This method is sub-jective, time-consuming, Pure tone threshold at 0.25-8 kHz for the three groups of ears Group Median pure tone threshold (range), (dB HL) ….
