Patent ID: 8858453

Claim:
A sound-output-control device comprising: acquisition means to acquire an anaerobic threshold; reception means to receive an input about exercise intensity; calculation means to calculate a target heart rate range of a user based, at least in part, on the acquired anaerobic threshold and the received input about exercise intensity; tempo-detection means to detect a physical-exercise tempo of physical exercise of the user; detection means to detect a current heart rate of the user; and control means to: control the tempo-detection means to detect, at a detection time, the physical-exercise tempo of the physical exercise of the user, to use the physical-exercise tempo detected at the detection time to set a tempo of a first sound signal to the physical-exercise tempo detected at the detection time, and to control a reproduction unit to output the first sound signal, and control the reproduction unit to output a second sound signal based on a result of a comparison of the target heart rate range and the current heart rate, such that a tempo of the second sound signal increases if the current heart rate is less than the target heart rate range, and decreases if the current heart rate is greater than the target heart rate range.
