Recently proposed method for measuring of sound scattering coefficients in a non-diffuse field is experimentally investigated. Such field can be created in a rectangular room with one absorbing surface. Other surfaces are covered by tested sound scattering elements, which scattering coefficient can be found by means of measured decay curve. Measurements were carried out in the room with dimensions 0.7x0.4x0.4 m at 4-16 kHz. Obtained results have demonstrated the possibility of proposed method for measuring of sound scattering coefficients.
