Dynamic parameters of the stapedius muscle reflex in response to stimuli of varying duration but with the same energy content.

An evaluation was made of the behaviour of the dynamic parameters of the stapedius contraction reflex (latency, amplitude, recruitment time, duration, and efficiency) in response to stimuli with the same energy content but of different duration. A comparison was made with the results of a similar experiment in which stimuli with different energy contents were used. As adumbrated in earlier studies, it was found that these parameters are more subject to the influence of the temporal characteristics of the stimulus than to its energy content.
