Admittance values associated with the acoustic reflex and reflex decay. 1976

D R Cunningham

Acoustic stapedial reflexes were elicited from 10 normal S's in each of three age groups. Susceptance and conductance values were measured for each subject in both the unreflexed and reflexed states and at 10-sec intervals during a continuous, reflex-sustaining stimulation with pure tones. Percentage of reflex decay over time was noted for each group and as a function of stimulus frequency and measurement mode. No significant age group differences were noted. Significant stimulus frequency and measurement mode differences were presented to represent "normal" reflex decay.
