Abstract:

The threshold sound pressure levels for the middle-ear stapedius muscle reflex in response to white noise constant spectrum level, and to pure tones and narrow bands of noise in the regions of 2 and 4 kilocycles per second, were studied with the Zwislocki acoustic impedance bridge and an objective recording method. Means and the shape of the distributions were provided. Mean thresholds for noise were as low as 62 decibels above audiometric threshold. Reliability and stability were high. It was concluded that the method could be used for a variety of purposes in audiometry, clinical audiology, and physiological acoustics and for such purposes this paper provides normative data from 30 normal-hearing young men.
