A Survey of Automobile Aeroacoustic Activities in Germany

This survey reports on the salient features of the approaches being pursued in Germany by automobile manufacturers, research organizations etc. to control and inhibit the noise emission from automobiles. The results reviewed are those presented by a number of experts from industry, research organization and universities during a Symposium held in February 1994 in Germany. Topics of concern were among others: sources of noise in automobiles, noise emission measurement techniques, aeroacoustic optimisation of car body and air conditioning equipment, design of and operational experience with new aeroacoustic wind tunnels in Germany.
