Particular Noise Reduction Method used to Mass Law
질량법칙을 이용한 연료펌프 특정음 저감 방법
Abstract
High frequency noise of fuel pump has does claimed by user. But high frequency of fuel pump can't heat in the car. But this noise Is an offensive noise outside car. In this study is noise reduction used to mass law. Especially high frequency (for example BPF(blade pass frequency)) is influenced of this law. In detail used to transmission and add to mass according to mass law, reduced particular noise. As a result high frequency is down until can't perception.
