Abstract
Research reported nearly 20 years ago concluded that the ability to make auditory pitch discriminations is impaired in some Ss by prolonged listening to sonar returns. As a special type of pitch discrimination, discrimination of doppler, is of importance in classifying sonar signals, an experiment was performed to determine whether or not listening to sonar returns for 90 minutes impairs the ability to discriminate doppler. No impairment was found. A second aim of this experiment was to evaluate the effectiveness of an alertness indicator when listening for sonar signals. With the indicator 16 per cent more signals were detected than without it.
