The Accuracy of Loudspeaker Array Sound Field Predictions Using Low-Resolution 1/3-Octave, 5Y Polar Data

Document Thumbnail

In a previous paper, a new method was presented that allowed a detailed prediction of array sound pressure fields when only low-resolution one-third-octave, 5o polar data was available for the individual loudspeakers in the array. The present paper investigates the accuracy of such predictions by comparing predicted and measured on- and off-axis frequency responses and polar patterns of a number of different array configurations. The predictions are based on complex summation of the sound pressure contributions from the individual loudspeakers in the array under the assumption that interaction effects, such as reflections, diffraction and shadowing among the loudspeakers in the array, are negligible. The way interaction effects can modify the array sound field and reduce the accuracy of the predictions is also discussed in the paper.:
