Although professional audio systems are primarily used for speech reinforcement and entertainment, they can play a pivotal role in life-safety notification in areas of public assembly. SimplexGrinnell provides planning and installation of Sound Reinforcement Systems that overcome the problems of acoustically challenged spaces and high ambient noise levels. Whether they are muted in emergencies or interconnected with other communications systems so that emergency messages are automatically reproduced, the key to their effectiveness is good audio design. 

System considerations typically include: analysis of the area’s physical characteristics (volume, height, sound absorption characteristics of walls, ceilings & floors, furnishings); planned uses; audience orientation and audio source orientation. The solution incorporates loudspeaker selection and orientation, frequency crossover, equalization, signal processing (dynamic controllers, compressors, expanders, limiters, delays), and acoustical gain analysis to allow maximum microphone usage flexibility. Whether the system is planned by our own sound specialists, or we employ the professional services of outside consultants, SimplexGrinnell ensures that the result will be effective, intelligible, flexible, and pleasing for the audience.

Applications

Assembly Areas
Whether for a cafeteria, multipurpose room, large meeting room, ballroom or auditorium, the main considerations are uniform loudness (decibels) and a high level of intelligibility (speech transmission index) across the entire area, and the flexibility for audio source input to support multiple usages. Auditoriums may also require stage performance equipment and visual projection equipment for special events .

Gymnasiums
In addition to ordinary design considerations for any assembly area, gymnasiums pose a particular acoustical challenge due to reverberation. A more focused approach may be used to emphasize loudness and intelligibility within seating areas.
