Large-scale loudspeaker system calibration, from simulation-based design to onsite tuning

The objective of a calibration is to ensure that the onsite performances of a loudspeaker system meet specific project requirements. It implies the optimization of the solution that was defined at the design stage, accounting for the environment in which the system was implemented.

Simulation-based design also allows to anticipate most of the electronic settings to further reduce the onsite tuning time. One additional and major benefit is that a 3D simulation gives an overview of the results over the whole audience area, whereas onsite tuning needs to rely on a limited number of measurements locations, leading to high risk of wrong electronic adjustment choices.

This seminar presents a complete optimization process that starts at the design stage, planning the physical deployment parameters, the zoning groups within line source arrays, the optimal main-sub alignment location and the time-alignment of fill systems. Onsite tuning can then use measurements and critical listening to validate the planned solution and to address remaining simulation uncertainties.
