Acoustics and vibrations

Abstract

Acoustics and Vibration technology for car development has gained significance and made major progress over the last few years. Sound patterns and volume of noises, as well as frequency and volume of car vibrations have to be considered while the car is being developed. Noises perceived as unpleasant should be very faint while warning noises have to be loud enough to meet certain safety standards. In addition, the noises of middle class and superclass cars are ‘designed’ in such a way that they correspond to what the customers expect. This is also true for any noticeable vibrations. The driver is in contact with the wheel and feels any vibrations occurring there at all times. The design of these vibrations of the steering wheel, including mounted parts and body, with regard to comfort is a major task. How acoustics and vibrations are perceived is an increasingly important argument for the decision to purchase.
