Vertical line arrays are nowadays the standard solution for large scale sound reinforcement for several well known advantages. But they carry also critical issues, like distance dependent frequency response, governed by parameters like single box height, HF vertical dispersion, as well as array length and curvature. On the field this leads to solutions that goes from array shape optimization to multichannel DSP processing (relying on a prediction software). The authors felt the necessity to investigate distance dependent frequency response with a simple and quite general (Matlab) model, not based on single element measurements but on parametric curved sub-arrays, in order to explain the very nature of involved phenomena with simplicity and generality and graph results in a meaningful way.
