To compare morphologies of crossed and uncrossed acoustic reflex waveforms.
Subjects were 12 young adults with normal hearing. A signal-averaging technique was used to compare onset and offset latencies of crossed and uncrossed acoustic reflex waveforms when maximum amplitudes were matched.
Onset latency was similar for the two modes, but offset latency was significantly longer for the crossed reflex. Further, in individual subjects the difference between crossed and uncrossed offset latencies was inversely proportional to maximum reflex amplitude.
Results emphasize the complex interaction between amplitude and latency characteristics of the acoustic reflex waveform.
