[The influence of various acoustic stimuli upon the cumulative action potential (SAP) of the auditory nerves in guinea pigs (author's transl)].

The impact of various acoustic stimuli upon the cumulative action potential of the auditory nerves in guinea pigs is investigated by means of the averaging method. It was found that the potential amplitude within the measuring range increases with the logarithm of the rising sonic pressure velocity. Unlike the evoked response audiometry (ERA), this potential seems unsuitable for furnishing information of the frequency-dependent threshold course.
