• Diffusors are used to reduce or eliminate repetitive echoes that occur in rooms/halls having parallel walls and a flat ceiling. Although there are different philosophies about how much natural reverberation recording studios and listening rooms should have, all professional studio designers agree that periodic reflections caused by parallel walls are best avoided.
  • Therefore, diffusion is often used in addition to absorption to tame these reflections. Such treatment is universally accepted as better than making the room completely dead by covering all of the walls with absorbent material.
  • For me, the ideal listening room has a mix of reflective and absorptive surfaces, with no one large area all live or all dead sounding. Understand that “live” and “dead” as described here concern only the mid and upper frequencies. Low frequency treatment is another matter entirely, and will be described separately. #Acoustics, #Audio, #Sound, #Noise, #Roomacoustics, #Diffusers, #absorbers.
