适用范围：This International Standard specifies a method for measuring the spatial sound distribution curve(s) of a given workroom.A method is given for determining ,from the measured data,two descriptors of the acoustical perfomance of a workroom regarding noise control:i.e. the exces of sound pressure level with respect to a free field, and the sound pressure level decay per distance doubling.
