ABF260 W200Delivering clear and intelligible messages

In a tunnel the PA system is the ONLY way of communicating with the passengers once they are outside their vehicles. More often than not these systems are now Public Address/Voice Alarm systems, so they are also used as the primary form of communication in the event of a fire or other emergency.

The most effective PA/VA system is the one that delivers a clear and understandable message the first time. In an emergency situation this means that passengers can act quickly and precisely to the message and in more day to day scenarios it means that tunnel operators can effectively communicate to tunnel users to prevent minor incidents escalating into larger emergency scenarios.

Road tunnels are very difficult acoustic environments which pose a significant challenge to the sound system designer. Well back in the late 1990's the company embarked upon a research project to develop a loudspeaker specifically designed to meet the challenges of the tunnel environment, the AXYS ABF260 loudspeaker was the result of this research project. The ABF is designed to deliver the best possible intelligibility in the very challenging acoustic environment of a tunnel. The AXYS ABF260 is designed to be the ultimate message delivery service in tunnels; delivering clear and intelligible announcements to the occupants of a Tunnel.
