Using a reaction-time procedure, pure tone thresholds were measured behaviorally in four baboons at 12 frequencies, ranging from 62 Hz to 40 kHz. Lowest mean individual thresholds were in the range of 3 to -8 dB SPL between 1.0 and 16.0 kHz, and rose to 48 dB at 62 Hz, and 59 dB at 40.0 kHz. These threshold functions closely match those of other Old World monkeys.
