Six latencies were measured of the stapedial refiex by analyzing compliance curves in an inkwriting recorder connected to an impedance audiometer. To produce stapedial riflex, pure tone (500-4000Hz) stimuli were presented to the opposite ear of 20 Japaneses (19-20 years of age) with the normal eardrums and with no known history of ear diseases.
The following results were obtained:
As the stimuli increased in each frequency, latency-stimulus curves indicated that (1) initial reflex response and precontraction response decreased, (2) reflex relaxation and reflex decay increased, and (3) initial off response did not show much changes.
There were the following relations between the latencies:
initial reflex response <reflex contraction time
initial off response <reflex contraction time
initial off response <reflex decay
precontraction response<initial off response
Numerical data were presented in figures and tables.
