Experimental Investigation on the Effect of different Bumps on Car Noise Emission 2006-01-0486

Today, reducing the noise emitted from vehicles is of great concern in the vehicle design. Recent reports state that the noise level increases close to bump area in the streets. In this paper effect of bumps on the emitted noise from car is investigated experimentally. The experiments in this paper are performed using two various passenger cars and two different types of bump with a noise level analyzer (B&K 2060). Obtained results show that bumps increase the emitted noise level from car up to 19 dB (A).
