7. 6 concludes that the diffuse field coefficient should be set equal to the absorption at 55 degrees angle of incidence. The 55 degrees was found in experiments conducted after the present. The maximum error is 0.9 dB for 100 and 125 Hz for reflection No. 5. For all other situations the error is smaller than 0.5 dB.
