ISO 17497-1 is the first part of the multiple series that specifies a method of measuring the random incidence scattering coefficient of surfaces as caused by surface roughness.
The measurements are made in a reverberation room, either in full scale or on a physical scale model. The measurement results can be used to describe how much the sound reflection from a surface deviate from a specular reflection. The results obtained can be used for comparison purposes and for design calculations with respect to room acoustics and noise control.
Note: ISO 17497-1 method is not intended for characterizing the spatial uniformity of the scattering from a surface.
Who is ISO 17497-1 - Measurement of sound-scattering properties of surfaces for?
ISO 17497-1 on sound-scattering properties of surfaces is useful for:
The degree of acoustic scattering from surfaces is very important in all aspects of room acoustics (e.g., in concert halls, sound studios, industrial halls and reverberation chambers).
ISO 17497-1 specifies a test method for the absorption coefficient that is useful in room-acoustic calculations, simulations, and prediction models. ISO 17497-1 provides a general principle of the method for measuring sound-scattering properties of surfaces for different orientations of the test sample in the free field.
Overall, ISO 17497-1 enables you to quantify a surface's scattering qualities to replace previously used but not widely accepted estimation approaches.
