适用范围
This 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 performance of a workroom regarding noise control: the excess of sound pressure level with respect to a free field, and the sound pressure level decay per distance doubling.
