MECHANICS OF NOISE GENERATION BY GROUND TRANSPORT VEHICLES

Motor vehicle noise is discussed in terms of the individual noise sources in trucks, automobiles and other vehicles. The sources include the engine and transmission, the tires (and where they meet the roadway), and the body of the vehicle and its appurtenances. There are several physically different mechanisms by which motor vehicle noise is generated. They are loosely grouped as being mechanical (impact, vibration), aerodynamic (interrupted flow, turbulence) and acoustic (exhaust and induction, tire/roadway interaction, combustion processes). The character of the mechanisms and their relative importance to the overall vehicle noise spectrum are discussed.
