| Abstract: | This letter disputes the contention that the growth of temporary threshold shift (TTS) with time can be adequately described by Gompertz functions. The similarity between TTS growth functions in high levels of impact and of continuous noise is stressed, a similarity that leads to the proposition that some sort of peak-limiting action that occurs at the stapes serves to protect the cochlea in the 120-dBA region. |
