ABSTRACT

The problem of automobile low-frequency noise reduction is very important due to the spreading for a long distances without significant absorbtion, passenger discomfort etc. For automobile equipped with internal combustion engine forming of either internal or external noise is mainly caused by engine operation. Complex approach to automobile low-frequency noise attenuation is suggested using active noise control method. Intercommunication of engine compartment and passenger compartment and cohearent low-frequency sound radiation by air-suctioning pipe and exhaust pipe are taking into consideration. Experimental unit, experiment methods, active noise control units construction with improved protection etc. are described. The ways of further investigations are suggested. Complex approach to active noise control method using is seems to be a promising solution for vehicles creation with improved environmental and consumer's qualities.
