Abstract

For some purposes it may be of interest to generate sound zones with different acoustic prop-erties in a room. This paper compares two strategies for generating such zones. One method is based on ‘contrast optimisation’: the idea is to maximise the ratio of the potential energy in a ‘bright’ (ensonified) zone to the potential energy in a ‘dark’ (quiet) zone with a given source configuration. An alternative method based on ‘sound field synthesis’ has the more ambitious goal to control the sound field in the bright zone in detail, for example, to generate a plane wave that propagates in a certain direction. The two methods are analysed theoretical-ly and examined through simulations and experimentally.
