animals, but with limited effects.

According to the article Significance of the stapedius reflex for the understanding of speech, the latency of contraction is only about 10ms, but maximum tension may not be reached for 100 ms or more.According to the article Le traumatisme acoustique, the latency of contraction is 150 ms with noise stimulus which SPL is at the threshold (ATR), and 25-35 ms at high sound pressure levels. Indeed, the amplitude of the contraction grows with the sound
