Optimising the Curving of Line Source Arrays

Analytical and numerical approaches

• Broschiertes Buch

Produktbeschreibung

Line Source Arrays (LSAs) are used for large-scale sound reinforcement aiming at the synthesis of homogenous sound fields for the whole audio bandwidth. The deployed loudspeaker cabinets are rigged with different tilt angles and/or electronically controlled to provide the intended coverage of the audience zones and to avoid radiation towards the ceiling, reflective walls or residential areas. This work intends to adapt an existing analytical optimisation approach for sets of discrete tilt angles in accordance to the restrictions of commercially available state of the art Line Source Array (LSA) systems. A research into various commercially available LSA systems will be carried out to determine a suitable set of angles to use as optimisation targets, followed by the discretisation of the algorithm's resulting tilt angles. As an alternative approach, a numerical optimisation based on the goal attainment method will be applied to the tilt angles. The results of the different optimisation approaches will be compared with the help of technical quality measures.
