Contour charts are given of the sound fields near one, two, or three reflecting surfaces at fight angles, for random sound incidence. The charts show contours of the mean‐squared pressure in decibels as a function of position in the region within two wavelengths of the boundary surfaces. The boundary conditions at the reflecting planes are pressure‐reflecting (normal velocity component equal to zero) or pressure‐release (pres‐ sure equal to zero). By reciprocity, the charts also give the relative radiation resistance of a point source as a function of position near such reflectors. The formulas used are tabulated; they extend and in some places correct formulas given in an earlier paper [J. Acoust. Soc. Am.27, 247–258 (1955)]. The features of the sound fields near the reflectors are discussed, and some applications to acoustical measurements in reverberant sound fields are considered.
