标准编号：ISO 717-1:2013

中文名称：声学 建筑和建筑构件的隔声标定 第1部分：空气声隔声

英文名称：Acoustics — Rating of sound insulation in buildings and of building elements — Part 1: Airborne sound insulation

标准范围

ISO 717-1:2013:a）定义了建筑物和建筑构件（如墙壁、地板、门和窗）中空气传播隔声的单数量；b） 考虑各种噪声源的不同声级谱，例如建筑物内的噪声源和建筑物外的交通；c） 给出了根据ISO 10140-2和ISO 140在三分之一倍频程或倍频程波段进行测量的结果确定这些量的规则-4和ISO 140-5。符合ISO 717-1:2013标准的单数字量旨在对空气传播隔声进行评级，并简化建筑规范中声学要求的制定。对于不确定度的表示（频谱适应项除外），还需以0.1 dB的步长进行额外的单数值评估。根据不同的需求，指定了单个数字量的所需数值。单个数字量基于一次测量的结果-第三个八度音阶或八度音阶。对于按照ISO 10140进行的实验室测量，应仅使用三分之一倍频带计算单个数字量。在扩大的频率范围内进行的测量结果的评级在附录中进行了说明。

ISO 717-1:2013: a) defines single-number quantities for airborne sound insulation in buildings and of building elements such as walls, floors, doors, and windows; b) takes into consideration the different sound level spectra of various noise sources such as noise sources inside a building and traffic outside a building; c) gives rules for determining these quantities from the results of measurements carried out in one-third-octave or octave bands in accordance with ISO 10140-2, ISO 140-4, and ISO 140-5.The single-number quantities in accordance with ISO 717-1:2013 are intended for rating airborne sound insulation and for simplifying the formulation of acoustical requirements in building codes. An additional single-number evaluation in steps of 0,1 dB is indicated for the expression of uncertainty (except for spectrum adaptation terms). The required numerical values of the single-number quantities are specified according to varying needs. The single-number quantities are based on results of measurements in one-third-octave bands or octave bands.For laboratory measurements made in accordance with ISO 10140, single-number quantities should be calculated using one-third-octave bands only.The rating of results of measurements carried out over an enlarged frequency range is dealt with in an annex.
