THE ACOUSTIC REFLEX FOR FILTERED BROAD-BAND STIMULI - A LESSER CONTRIBUTION OF THE LOWER FREQUENCY NEURONS

The effects of the cut-off frequency of the filtered broadband stimuli on the human acoustic reflex (AR) were examined to observe the relati on between the area of excitation in the cochlea and the AR response. The results obtained have indicated that all the input from the cochle ar region does not equally contribute to trigger the BR equally; i.e., there is a lesser contribution from the frequency region below 700 Hz .
