The physiological and behavioral effects of radio music on singly housed baboons (1996)

Brent, L., Weaver, D.

Abstract

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. Vocalization [of the single-housed subjects] was twice as high when the radio was off. Blood pressure did not vary with radio condition, but the heart rate was significantly lower when the radio was playing.
