Abstract

An acoustic control device (100) comprises an output unit (101), an acquisition unit (102), and a control unit (103). The output unit (101) outputs a reproduced sound based on the input of a broadcast wave such as a radio broadcast wave or a television broadcast wave or of a recording medium such as a CD or a MD. The acquisition unit (102) acquires, if a moving body undergoes an impact equivalent to a collision or an impact equivalent to sudden braking or abrupt steering, an impact signal corresponding to the impact. The control unit (103) reduces the volume of the reproduced sound output from the output unit (101) when the acquisition unit (102) acquires the impact signal.
