The effect of calibration tolerance values on obtained audiometric threshold: a hearing conservation perspective.
Auditory threshold was assessed at six commonly used audiometric test frequencies and for frequencies just within calibration tolerances for frequencies above and below these. Results indicate that differences of up to 23 dB in obtained auditory threshold values result from variation in frequency within tolerances. These findings are discussed in terms of their importance in industrial hearing conservation.
