Ultrasound and Infrasoundst obvious characteristic of these sound types is that, by definition, they are “extreme” frequencies that fall outside the normal response curve for the human ear (see Figure 1) and are therefore inaudible. Ultrasound, which includes biologically significant sounds ranging from 15 kHz or so up to 2

Sound Playback Studieshington, D.C., had begun recording animal vocalizations. As part of his effort to decipher “the speech of monkeys”, Garner conducted some of the first sound playback experiments. He reasoned that by replaying the vocalizations to animals and watching their reactions, he could learn the functions of
