acoustic Duplo panel, the Story

2 techniques of echo management

2 techniques

In interior spaces, there exists 2 techniques of acoustical dampening for the effective control of echo. Or more specifically, the reverberation time – the long fade of an echo.

We have the traditional technique, of materials that by their mass – thickness – absorb the energy of soundwaves.

Then we have diffusors. A whole different technique, where uneven surfaces scatter (split up) soundwaves. Which, from this surface are then reflected as many, many, smaller waves – with many, many, different paths.
