Relationship between hair cell loss and temporary threshold shift in goldfish. (A) Mean (±S.E.) percent hair cell loss (solid circles) and temporary threshold shift (TTS; open circles) as a function of exposure tone frequency. A decrease in both hair cell loss and hearing loss is seen with an increase in the frequency of acoustic exposure (N = 23). (B) Mean temporary threshold shift as a function of mean percent hair cell loss for individual goldfish (N = 23). Means are averaged across all saccule locations for hair cell loss and across all frequencies tested for threshold shifts.
