TunnelSafe and Sound: Optimized Sound Communications for increased safety in tunnels

The echo in tunnels has, until now, made the emergency communication over loudspeaker virtually impossible. Now scientist are exploring possibilities to make such instructions clearer. They are developing techniques to time-aligned the signals so as the sound waves don’t cancel out each other.

Another case of the importance of sound for communication. Flashing lights will get the attention but sound will make it possible to deliver specific instructions which could be a life-saver.
