Public Alert Systems (PAS’s) provide an audible warning signal to alert people of possible immediate harm, thereby saving lives in addition to minimizing corporate liability and associated financial loss. PAS’s can signal evacuation orders in the event of industrial spills, fires, and any other circumstance likely to put lives at risk.
Unless the warning signal is audible above the ambient noise environment, and sufficiently attention-grabbing to convey a message of danger, it will not function effectively in prompting evacuation and preserving lives.
BAP Acoustics provides specialized audibility design services for both outdoor and indoor public alert systems. Our extensive experience in both human sound perception and acoustic modelling ensures design specifications for PAS’s meet the audibility criteria of ISO 7731.
