The object of the seminar is to provide a closer look at large room acoustics and the knowledge and competency to design a suitable a professional sound reinforcement system, capable of achieving the correct coverage and intelligibility. System commissioning, tuning and optimization will be discussed as well.
- Acoustics of interior environments
Reflection, transmission and absorption of sound, different materials absorption coefficient, Energy time curve, early reflection, reverberant field, reverberation time (RT) and critical distance. RT prediction.
- Sound Reinforcement Systems
Loudspeaker systems selection criteria (constant directivity, cluster, line array) and types of sound reinforcement systems (L-R, L-C-R, distributed system, surround). Sizing of the sound system (coverage angles, sound pressure level, uniformity, headroom). Delay lines (use of delay lines, delay calculation).
- Amplifiers and Cables
Passive speakers, cables and wiring, amplifier and system configuration, notes on active loudspeakers.
Signal processors, crossover, equalization and phase alignment of professional speaker systems.
- Software Simulations
Significant data , Q factors (direct and total SPL, intelligibility) and calculation formulas, how to read and compare results.
