Abstract : Any complex sound has a pattern of components which may or may not be possible for the human ear to detect. Sonar operators attempt a generalized recognition of signals which are synthesized sound patterns. The aim of the present experiment was to look for differences between discrimination of the cues, or acoustical components, in sounds heard, and those in the same sounds transformed into a visual display. The sounds used previously were transformed by spectrography into visual sections from which slides were made for screen presentation. Twenty-three sailors with good visual acuity acted as subjects. The statistical analysis is based on the 3680 responses in the test sessions.
