Finite Element Analysis of Near Field Beam Forming in Safety Relevant Work Spaces
Due to unique features, loudspeaker arrays are an interesting alternative to standard loudspeaker setups or headphone-based solutions in security relevant workspaces such as air traffic control rooms. Consequentially, near field beam forming in small spaces plays an important role for this field of application. In this contribution, the sound design based on a set of loudspeaker arrays featuring their interaction with a typical air traffic control room infrastructure is investigated by means of finite element modelling. Guided by these results, optimized array parameters can be determined. Representative three-dimensional near field directional diagrams in front of the arrays are shown to visualize the sound field in different cases. Finally, these theoretical values are compared with practical results.
