Claims (1)

암소음레벨보다 돌출해서 발생하고 있는 기어맞물림소리와 같은 고유의 주파수를 가진 노이즈를 산출하는 노이즈 검지수단과, 가청영역의 주파수로 이루어진 화이트노이즈를 발생하는 화이트노이즈 발생기와, 이 화이트 노이즈 발생기가 발생하는 화이트노이즈를 차실내를 향해서 출력하는 스피이커와, 적어도 상기 노이즈가 발생하는 주파수 대역에 있어서, 상기 노이즈의 음량보다 약간 작은 음량의 화이트노이즈를 상기 스피이커로부터 출력하도록 제어하는 제어회로를 구비한 차량의 노이즈 소거장치.Noise detection means for calculating noise with inherent frequency such as gear engagement sound protruding above the noise level, white noise generator for generating white noise composed of audible region frequency, and this white noise generator A vehicle having a speaker for outputting white noise toward an interior of the vehicle and a control circuit for controlling the speaker to output white noise having a volume slightly smaller than the volume of the noise in at least a frequency band where the noise occurs. Noise canceller. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
