This investigation analyzes measurements of the reflected sound field from various reflector panel arrays. A previous study by the third author [R. R. Torres and M. Vorlaender, ‘‘Scale-model MLS-measurements of scattering from overhead panel arrays,’’ Acta Acustica (in press)] measured impulse responses using the maximum length sequence method at various receiver positions from six scale-model panel arrays of different sizes and densities. This study included an octave band analysis of reflected magnitude as a function of receiver position. The current authors have extended the research by conducting a narrow-band analysis of magnitude and phase of the reflected sound fields for three of the panel arrays [J. Rathsam, L. M. Wang, and R. R. Torres, J. Acoust. Soc. Am. 117, 2499(A) (2005)]. This study revealed a close relationship between phase and magnitude. The current work continues the analysis of reflected phase and magnitude for the three additional reflector panel arrays. The newer arrays are more complex and may reveal the effects of multiple diffraction more clearly than the previous three arrays.
