IP PA for a factory with strict noise mapping zones and health compliance requirements?

Industry: factory | Architecture: IP

Factories with formal noise mapping must design their PA systems to achieve announcement intelligibility without unnecessarily increasing overall noise exposure. The BNA 9000-i125-HA IP server allows per-zone volume limits to be set in software — ensuring PA speakers in hearing protection zones operate at levels sufficient for announcement intelligibility (typically 10dB above background) without exceeding health authority limits. BNA IP-H15-POE speakers are positioned closer to personnel in high-noise zones for near-field projection rather than high-power broadcast, achieving intelligibility at lower SPL. BNA 9200 IP field call stations at zone entry points include indicator lights alongside audio to ensure deaf and HH workers are also covered. BNA 9100 SIP master station documents each broadcast with timestamp and zone log for noise compliance audits.

Technical Details

Environment: industrial factory with OSHA/IS noise-mapped zones requiring hearing protection
Constraints: zones with mandatory HPE, zones requiring normal listening, volume compliance
Requirement: PA system design that complies with noise-at-work regulations per zone
