Ultrasonic Sound

The use of ultrasonic sound as a means of controlling rat populations is questioned. The following points are discussed: (1) the processes of refraction and decreased audiogenic seizure susceptibility with repeated exposure to sound; (2) the genetic variability of the rat with respect to auditory behaviors; (3) the behavioral and physiological responses of organisms other than the rat; and (4) the behavioral responses of rats to ultrasonic sound at distances from the sound source. It is concluded that such a device may be effective under certain circumstances, but more data are needed with respect to the behavioral and physiological effects of ultrasonic sound before it is used for rat control.

Role of pinnae and head movements in localizing pure tones 1The authors would like to thank Mr. Remi Humbert for implementing the experiment in Turbo Pascal and for his further assistance.

Pure Tones

Twelve blindfolded subjects localized two different pure tones, randomly played by eight sound sources in the horizontal plane. Either subjects could get information supplied by their pinnae (external ear) and their head movements or not. We found that pinnae, as well as head movements, had a marked influence on auditory localization performance with this type of sound. Effects of pinnae and head movements seemed to be additive; the absence of one or the other factor provoked the same loss of localization accuracy and even much the same error pattern. Head movement analysis showed that subjects turn their face towards the emitting sound source, except for sources exactly in the front or exactly in the rear, which are identified by turning the head to both sides. The head movement amplitude increased smoothly as the sound source moved from the anterior to the posterior quadrant.
