More speakers don’t mean more safety.
It’s common to think that in a voice evacuation system, the more speakers you install, the better the message will be heard.
But it’s not that simple.
A voice evacuation system isn’t about power or volume.
It’s about something far more important: making sure the message is clearly understood.
Because in an emergency, understanding an instruction can make all the difference.
A simple example:
A building filled with poorly placed speakers might have areas where sound overlaps or becomes unclear.
In contrast, a well-designed system, with the right speakers placed strategically, ensures that everyone hears the message clearly and without interference.
What really matters:
- Proper speaker distribution
- Balanced sound levels according to each environment
- Room type and reverberation control
- Compliance with EN 54 standards
At UDE, we design EN 54 certified speakers to ensure every word reaches every corner with accuracy and clarity.
And through our Projects Department, we provide technical support to help engineers and installers define the best acoustic solution for each space.
Because in an emergency, it’s not enough to hear.
You need to understand the message.
