The sound we hear in indoor environments is primarily composed of direct sound and early reflections. Proper reduction of the reflections received 50 milliseconds after the direct sound can improve speech clarity, while adding a moderate amount of reflections can enhance the richness of sound. By using diffusers effectively, incoming sound waves can be uniformly scattered, avoiding the propagation of reflections in a single direction and enhancing the fullness and uniformity of the sound.

Diffusers play a powerful role in distributing sound waves more evenly in a room. They can effectively expand the optimal listening area in a room, eliminate standing waves and echo reflections. This is why diffusers are often placed in the corners of walls, as corners are prone to generating standing waves.

Musicians and audiophiles appreciate the pleasure of sound in rooms with good diffusion because the diffused sound field creates an open and natural acoustic environment, making a small space sound grand and providing the most authentic sound reproduction. Additionally, diffusers contribute to adjusting the most important acoustic parameter of a room, namely, reverberation time. They scatter early reflections to every corner of the room, effectively improving the uniformity of the sound field.
