とする吸気消音装置。 a speaker disposed at a predetermined position in an intake pipe of an engine to add pulsating sound to the intake air flowing through the intake pipe; a crank angle sensor disposed in the engine to detect the rotation speed and crank angle of the engine; An air flow sensor is installed in the pipe and detects the intake air amount of the engine, and a waveform that is approximately the same as the intake pulsation sound corresponding to the engine rotation speed is stored, and the signals from the crank angle sensor and air flow sensor are read and the corresponding waveform is stored. An intake noise muffling device comprising: a computer that outputs a pulsation sound signal having substantially the same waveform and amplitude as the intake pulsation sound at the detected engine speed and an opposite phase, and adds the signal to the speaker.
