Volume amplitude limiting device
Abstract:
A volume amplitude limiting device includes a volume adjustment unit, an amplitude limiting unit, and a control unit. The volume adjustment unit adjusts the amplitude of an input sound signal to a larger degree as the adjustment value increases and outputs the resulting sound signal. The amplitude limiting unit limits the amplitude of the sound signal output from the volume adjustment unit to an output limitation value and outputs the resulting signal to a speaker. The control unit sets an adjustment value for the volume adjustment unit and also sets an output limitation value for the amplitude limiting unit according to an adjustment value.
