Abstract
The, attenuation of low-frequency sound, passing at near grazing incidence over audience "seating, was investigated by examining spectra of the direct and early arriving sound. Detailedmeasurements in one hall and on scale model seats showed the frequency of the principalattenuation minimum to be related to the vertical angle of incidence as well as to the presenceof additional early arriving sound energy. Octave band measurements in 11 halls demonstrated'that the low-frequency attenuation was strongly influenced by the geometry of the halls and inThe, attenuation of low-frequency sound, passing at near grazing incidence over audience "
