dc.description.abstract	Standard surround systems for generation of isolated wideband soundfields employ uniformly-spaced array of speakers in the horizontal plane. For these systems, the evaluation of sound reproduction with height is important due to listener's variable heights.

Abstract:

Standard surround systems for generation of isolated wideband soundfields employ uniformly-spaced array of speakers in the horizontal plane. For these systems, the evaluation of sound reproduction with height is important due to listener's variable heights. Previous work demonstrated that controlling both the speakers' location and their complex weights using two-stage Lasso-LS pressure matching optimization allows isolated sound reproduction with limited number of speakers within the speakers' plane. This work demonstrates that deployment of this technique can also give up to 24dB in suppression of sound at heights between zero and one meter from speakers' plane over single-stage LS using e.g. 90 speakers in a semicircular array. © 2013 IEEE.
