    摘要： An engine rotating speed sensor detects intake sound information due to the drive of an engine. A controller generates a signal having a frequency corresponding to a desired ratio of orders based on the detected intake sound information. Further, a phase and an amplitude the signal are controlled, and so a speaker arranged in a propagation path of the intake sound of the engine generates control sound to control the intake sound due to the drive of the engine. An engine noise control apparatus which is capable of effectively reducing or waveform-reshaping a wide range of engine noise. The apparatus has an engine rotating speed sensor for detecting an engine rotating speed and a waveform generator circuit for converting a rotation pulse signal to a periodic signal having a frequency which is a predetermined multiple of the detected engine rotating speed. The output of an air flow meter is passed through a bandpass filter and a reshaping circuit to generate a control signal which is an average value of alternating current components of the output. A CPU, with reference to a map previously stored in a memory, modifies the phase and amplitude of the periodic signal with respect to an engine rotation reference signal based on the rotation pulse signal and the control signal, and outputs the modified signal as driving signals to operate speakers disposed in an intake tube and an exhaust tube for reducing noise.

    摘要： A noise control apparatus has a thermal-type air flow meter for detecting engine load, an engine speed sensor for detecting engine speed, and an intake temperature sensor for detecting intake temperature. The engine load is detected based on the surging components of the signal from the air flow meter. An intake pipe is provided with a speaker that produces a noise control wave in accordance with a control signal from a controller. The controller has a memory that stores map data for noise control waves that are equal in sound pressure but opposite in phase with respect to intake noise. The map data regarding sound pressure and phase correspond to the engine load and speed on the basis of a reference temperature. A CPU of the controller computes a map-reading engine speed value based on a wavelength of intake noise that is determined based on intake temperature and engine speed, such that the map-reading engine speed value provides at the reference temperature substantially the same wavelength as that of the intake noise. The CPU generates a noise control wave signal based on the map-reading engine speed value and engine load information.
