Paper Abstract
Knowledge of the variability of the acoustic emission characteristics from SCUBA divers is critically important for
designing and operating a passive acoustic SCUBA characterization system. Using modeling and experimental
measurements in a controlled environment, we identified key source factors influencing the variability of the acoustic
emission parameters including Source Band Level (SBL), Spectral Power Density (SPD), and breathing periodicity or
emission modulation frequency. The key factors are: equipment, specifically, the design of the first stage (high pressure)
regulator and its service life; diver's experience and training; and, finally, operating conditions of the equipment and
diver, i.e. tank air pressure and the diver's motion activity. We found, for example, that the SBL could vary as much as
16 dB depending on the equipment used and up to 15 dB depending on the diver's intensity of motion.
