Information on the availability of noise control products, their characteristics and specifications, and their supply sources is included, along with a discussion of operating principles, uses, and limitations of the products. Applicable noise control standards are provided. Tabulated sound absorption coefficients are presented for various types of mufflers, silencers and ducts." - NIOSHTIC-2 NIOSHTIC no. 00095999
