This effect was seen for 500, 1000, and 2000 Hz reflex-eliciting signals. The results also showed that there was no effect of gender on latency changes in acoustic reflexes.CONCLUSIONS: Latency changes may explain efferent auditory system mechanisms used for the protection of the cochlea and improvement in speech perception. Thus, contralateral changes of ARL can serve as an additional tool to assess the efferent system functioning.
