Second, their high-frequency hearing is severely limited, with their hearing range at 60 dB sound pressure level [SPL] extending from 65 Hz to only Third, determination of the effect of duration on noise thresholds indicates that, compared with other animals, mole rats require a sound to be present for a much longer duration before reaching asymptotic threshold.
