Tunnels present particularly demanding acoustic conditions: high reverberation, changing ambient noise and situations where every second counts. At UDE, we design public address and voice evacuation systems capable of maintaining optimal intelligibility even in these circumstances, thanks to advanced processing, filters, delays and modulation technologies that ensure every message comes through clearly and comprehensibly.

The length of tunnels requires power stages to be distributed, linked by network and synchronised throughout the entire route. Our solutions are designed to operate in critical scenarios, guiding users with clear and human instructions, especially in emergency situations.
With UDE, information is transmitted accurately and reliably in one of the most complex environments in the sector.
