摘要
本文提出海滨疗养区环境噪声为海浪声与海浪声为OdB时的环境本底噪声的合成,并介绍一种调查观测和实验方法,来分析海浪声L′及其对人的影响,着重分析了疗养房间开窗期间(5—9月份)海浪声与近岸风浪、涌浪、地形,海浪声强度、频谱与人的感受关系,研究结果表明,疗养人员对一般海况下的海浪声有好感和不受影响者在98％以上,影响睡眠的海浪声的发生率仅占2％以下,从而得出一般海浪声不应视为噪声且对人们有一定益处的结论,提出海滨疗养区环境噪声评价标准的建议。
In this paper it is assumed that environmental noise in a seaside sanatorium quarter is composed of wave sound and the background environmental notse when wave sound is absent (L = L0 + L'). To analyse the effect of wave sound on human beings, an experimental method is presented. The stress is cm the studies of the relation between sound from various waves (bores, wind-generated waves, swell) and topography, the relation between the intensity and frequency spectrum of wave sound and people's feeling during the windowopen pariod (from May to September). The results show that over 98% patients give a favourable or neutral comment on ordinary waves, and the rate of occurence of wave noise interfering sleep is below 2%. Hence we conclude that ordinary wave sound should not be regarded as noise and we make some suggestions concerning the evaluation criterion of the environment noise in seaside sanatorium quarters, which are of practical significance for the environment noise pre-evaluation and the siting of new sanatorium buiding in Qingdao and other seaside cities.
