Changes in skin conductance (GSR), skin potential (SP), heart rate (HR), finger blood volume (BV), and pulse volume (PV) were recorded in response to 2‐sec bursts of white noise. Five intensity levels of sound (60, 70, 80, 90, and 100 db) were presented over 5 repetitions. Results showed that: (1) response magnitudes and latencies were directly related to stimulus intensity and inversely related to number of repetitions; (2) for BV, SP, and GSR the effect of repetition varied with stimulus intensity; (3) HR changes were primarily monophasic; and (4) BV and PV were more sensitive to stimulus intensity differences than were the electrodermal responses.
