Frequency characteristics of the stapedial reflex was determined by application of contralateral sound stimulation modulated sine wave at several frequencies.
In the case of 23 normal subjects, the stapedial reflex showed responses similar to signal sine wave up to 1.04Hz. From 1.04Hz to 3.20Hz, stapedial reflex decreased in amplitude following -6.7dB/oct line. Beyond 3.10Hz, amplitude of the stapedial reflex decreased rapidly with -26.8dB/oct line.
Facial paralysis usually accompanied stapedial muscle paralysis. On the way to recovery, the reflex showed the same pattern of frequency response, but its amplitude was less than the normal side.
