노면 변화에 기인한 자동차 도로소음에 관한 실험적 연구

Noise of the automobiles the part which relates the tendency which prefers the gradually quite vehicle with advancement and consumer demand level augmentation of technique is coming to be high, in order controls the tire noise which is considered seriously among the rest effectively from the evaluation which is objective and relationship between of the evaluation which is management appropriately, must define. Specially sound quality of the automobile inside simply sound arresting the inside in compliance with a size knows that is decided, in compliance with the quality of the frequency band which forms the sound market about the evaluation which is appropriate is demanded in order to undergo an influence. From the research which sees for the reduction which automobile tire noise is effective measures the plan condition and vehicle speed and the road surface of the tire affect in automobile road noise with the method which is objective and is measured. The following to this study, based on theoretical and experimental analyses, and the possibility of a low-noise tire development is presented and we have known that which road has noise characters from frequency.
