Sampling distortion product otoacoustic emissions (DPOAEs) at multiple f 2 /f 1 ratios and f 2 frequency values produces a DPOAE “map.” This study examined the efficacy of
Hearing loss (dB) at 8000 and 16000 Hz, between D7 and D0, between D30 and D0, and between D30 and D7, in the 6 guinea pigs studied for macroscopic anatomy and with poor hearing (hearing loss > 40 dB)
Purpose to characterize and to compare the hearing of employees of a public hospital exposed to maximum occupational noise levels above and below 85dB(A). Methods this clinical study selected 39 worke
