Abstract This chapter discusses the use of acoustic textiles in the transportation industry; the sector currently represents the most important application of textiles in the world. In general, acoustic textiles are used in the transportation industry to reduce interior noise and vibration and improve the sensation of ride comfort for the passengers. Interior noise is currently a competitive quality characteristic of every mode of transport facility in particular automobiles. Although interior noise lowers the comfort feeling inside a vehicle, it also induces fatigue and may reduce driving safety. The number of cars exceeds by many times the total number of other means of transport produced every year in the world. Therefore, the use and development of acoustic textiles have been more important in the automobile industry mainly because of economic reasons. A variety of sources contribute to the interior noise of a vehicle which can be structure-borne or airborne sound. Acoustic textiles used to control noise in vehicles must provide airborne transmission reduction, damping and sound absorption. However, the use of acoustic textiles in vehicles is not only dependent on their acoustic properties but also on additional characteristics. Selection of a particular material is also determined by its ratio between performance and cost. Acoustic textiles employed to reduce noise and vibrations are used either individually or as components of complex composite materials which are an interesting area of research. Although there are several books that have covered the subject of technical textiles in the transportation industry, this chapter aims to discuss those textile developments that are used mainly to provide noise isolation and sound absorption in different means of transport. This chapter is preceded by an introductory section. Then the use of acoustic textiles for noise control of main sources in cars is discussed. The final section is devoted to further applications of acoustic textiles in aircraft, trains, ships and spacecraft.
