高速铁路高架车站候车厅声学环境要求的研究
Research on the Requirement of Acoustical Environment in the Waiting Hall of High-Speed Railway Elevated Station
摘要
Abstract
Based on practical data of the acoustical environment in the waiting hall of high-speed railway el-evated station in China, consulting with domestic and foreign relevant standards, also by analyzing the feasibility of technology, four evaluation indexes of the requirement of acoustical environment in the waiting hall of high-speed railway elevated station in China are presented in this paper, which including the hour-equivalent sound level (Laeq,1 h) affected by the running noise of high-speed trains, the transit exposure level (Tel) of the passing train, the 500 Hz reverberation time (T60, 500 Hz) in the waiting hall and the speech transmission index (Stipa) of sound reinforcement system. Each evaluation index is classified in two levels, the allowable limit and the encouraged limit The allowable limit is based on the controllable technology at the present stage, which corresponds to Laeq,1h≤65 Db, Tel≤85 Db, (T60, 500 Hz) ≤2.5 s, StIPa≥ 0. 45. The encouraged limit is designed to keep passengers' comfort in the waiting hall, which corresponds to Laeq,1h≤60 Db, Tel≤80 Db, (T60, 500 Hz) ≤2. 0 s, Stipa≥0. 55, which can be achieved by optimizing the acoustic design and taking noise control measures.关键词
