The physiological and behavioral effects of radio music on singly housed baboons

The response of four singly caged baboons to radio music was measured using behavioral and physiological indices. Heart rate and blood pressure, measured through a tether system, as well as behavior, were recorded during a two-week period in which radio music was available in half of the samples. The behavior of the subjects, as well as their blood pressure, did not vary in relation to radio music. Heart rate was significantly lower when the radio was on.
