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, i.e. the excess of sound pressure level with respect to a free field and the sound pressure level decay per distance doubling. Data obtained from this standard are of use for: - the acoustical qualification of a room, - the determination of appropriate positions of a machine in a room, - the determination of the influence of shielding and scattering objects, - the determination of the effect of sound absorbing linings in different parts of a room, - the calculation of noise immission levels e.g. for the determination of rating levels. Is applicable to workrooms of any shape and any dimensions provided that the number of microphone positions allows the regression calculation to be performed.
