Abstract

The current research direction of vehicle noise control is to eliminate the harm of external noise to drivers and passengers, reduce external noise pollution and improve ride comfort. The cross-spectrum function at the vehicle vibration point can be calculated by combining the vibration signal on the vehicle chassis as the excitation signal of ANC control transfer function. The purpose of noise reduction in the driving cab is realized by using multiple coherence model. This method can effectively avoid the phenomenon of secondary acoustic feedback caused by the collection of reference signals in the cab, and improve the noise reduction effect in the cab. It provides a comfortable environment for driving and riding cars, and also provides a technical solution for the acoustic performance design of new models and the control of vehicle road noise.
