Tricky environments with clear acoustics
Public address and voice alarm systems for tunnels must compensate for complex situations of reverberation and ambient noise to ensure a clear understanding of the messages. Intelligent technologies based on filters and sound modulation help to compensate for these circumstances.
It’s a given that people act faster when they hear a human voice telling them what to do or how to proceed, especially in case of emergency.
LDA Audio Tech’s public address and voice alarm systems certified according to EN 54 and EN 60849 provide intuitive user management and are easily integrated with existing third-party technologies at tunnels.
LDA Audio Tech offers:
High intelligibility and directivity.
Integration with SCADA (Modbus or Ethernet).
