Popis: | International audience; The authors have proposed a two-rating method of evaluating impact noise isolation [LoVerde and Dong, J. Acoust. Soc. Am. 141 (2017)], in which low and high-frequency components are evaluated independently. The high-frequency rating is based on the existing IIC/Ln,w ratings, except with a limited frequency range encompassing the 400-3150 third-octave bands. The proposed ratings evaluate high-frequency impact sources and mitigation measures better than the existing ratings. These high-frequency ratings, called High-frequency Impact Rating or HIR for field testing and High-frequency Impact Insulation Class or HIIC for laboratory testing, have been approved and will be published as a new ASTM standard. Motivations, development, and examples illustrating the use of the new ratings are presented, and suggested classification schemes are discussed. |
