Abstract

The goal of this thesis was to investigate tetanic acoustic stimulation (TS) and its effects on the human auditory system. Two experiments were completed to study the effects of a 2 minute duration 1 kHz TS on the auditory brainstem and cortex using auditory evoked potentials. At the cortical level the auditory long latency response (ALLR) was recorded and the P1, N1, and P2 components were measured; in the brainstem the amplitude of the 80 Hz auditory steady state response (ASSR) was measured. TS induced significant changes in ALLR component latencies, and a significant reduction in ASSR amplitude, but these changes were not specific to the TS acoustic frequency of 1 kHz.
