An acoustic diffuser is an element that improves the sound quality of a space by uniformly distributing acoustic energy. Its operating principle is based on ensuring that sound, when reflected, does so in a homogeneous manner instead of concentrating in a single direction as would occur according to the law of sound reflections.
They are completely complementary to the absorbent treatments used in rooms to reduce reverberation times, as they help achieve greater sound uniformity.
Absorbents remove energy, while diffusers homogenize the energy without removing it. They increase the sense of spaciousness and sound intensity, regardless of direction, and help generate the same sense of volume throughout the room, helping to avoid echoes and coloration without losing the sense of liveliness.
