We have improved the acoustics in the language classroom. We completed the free space on the ceiling between the lights with a grid of acoustically absorbing Silentmax3D-line slats. The advantage of the system is quick and simple installation and the immediate effect of improving the acoustics of the room.
The graph below shows the echo drop by almost half.
Less echo = higher intelligibility of the spoken word. In a room with low echo, the speaker does not tend to shout over himself. More perfect acoustics improve the intelligibility of the spoken word, extend concentration and reduce listener fatigue.
