THE IMPACT OF CHINA'S TRAFFIC NOISE SPECTRUM ON THE SINGLE-NUMBER-QUANTITIES SNQs EVALUATION OF AIRBORNE

Year: 2022

Type: conference-paper

Abstract: The ISO 717-1 specified the spectrum adaptation terms Ctr, to take into account the spectra of is Aweighted urban traffic noise.It should be noted that the spectra Ctr was adopted from the Nordtest Method NT ACOU 061 (Nordtest, 1987).However, the means of transportation are undergoing great changes, so the characteristics of traffic noises are also changing significantly.Therefore, in order to better resolve the disputes caused by sound insulation and traffic noise in China, it is necessary to explore whether the existing evaluation standards are still applicable to various types of traffic noise.In this paper, the urban traffic noises in China have been measured and analyzed, a new spectrum adaptation terms for airborne sound insulation evaluation is established, and applied to the calculation of sound insulation of several common building components, and its applicability is discussed.
