城市居民区配套设备噪声频率特性分析
Analysis of Noise Frequencies of Facilities in Urban Residential Area
摘要
Abstract
The frequency spectrum as well as the energy ratio of low band, mid band and high band of noise sources in residential area from typical facilities including transformer substations, garages, elevator shafts, elevator control rooms, air conditioner external unit and pump houses were analyzed. The result showed that most of the maximal sound pressure levels appeared in the low band (five ones appeared in six typical noise sources) and most of the maximal energy distribution also appeared in the low band (five ones appeared in six typical noise sources). So the low-frequency noise was the biggest noise source in the resident area.关键词
