Interior Noise Reduction Methods for Heavy Trucks Using Acoustical Materials 891137
Interior noise levels in heavy trucks have been reduced to approximately 80 dBA as a result of a competitive industry responsive to driver comfort. In the future interior noise level design goals promise to be further reduced. This paper describes a method of meeting current and future interior noise goals with acoustical materials.
The paper reviews established noise control products and applications, identifies the benefits of giving attention to noise controls during the truck design stage, and discusses the use of Perceived Speech Interference Level analysis.
A laboratory noise control development project is described.
