Quantification of the parameters of the acoustic reflex in normal ears.
Measurement of the acoustic stapedial reflex parameters has proved to be a useful tool for evaluating the function of the acoustic-facial reflex. However, there is no agreement about the definitions of the parameters; moreover, most of the data have been obtained by manual measurement methods. The authors describe a computerized analytical method which permits the parameters to be measured according to the definitions and methods suggested by others and according to the new analytical method described, which is performed on the basis of the derivative of the stapedial reflex curve. The two methods are compared in 40 normal subjects.
