The phrase "sound diffusion" is correct and usable in written English.
You can use it when discussing the transmission of sound through an environment. For example, "The sound diffusion through the auditorium was excellent, allowing everyone to hear the performance clearly."
The saw-tooth shaped wall diffuser profile in the Chamber Hall was designed using glass-fiber reinforced concrete for mid-frequency sound diffusion.
The difference in B-term diffusion between fully porous and porous-shell particles is investigated using the physically sound diffusion equations originating from the Effective Medium Theory EMTT).
The vertically-patterned diffuser profile with protruded cubic surfaces in the M-Theater was designed using glass-fiber reinforced gypsum for sound diffusion in the major speech frequency range.
We've attended a number of these Diffusion Sessions over the past year or so you'd be crazy not to and what's great about the shows is that, where possible, Haswell & Hecker are situated in the centre of the space, controlling the 360 degree sound diffusion, leaving the audience free to wander around them.
Observations of spontaneous behaviour within the social group and/or of randomly selected control videos (during mock experiments with no sound diffusion) revealed that subjects (1) presented no motor or sensory problems concerning head orientation and eye movement, (2) displayed no natural side-preference for head orientation (left vs. right).
We selected a reaction as a valid response when it was the first orientation (GO, HO or FR) consecutive to the sound diffusion, and when it occurred within a threshold delay of 1.0 s (GO), 1.4 s (HO) and 1.4 s (FR) for the monkeys and 1.2 s (GO), 1.4 s (HO) and 1.2 s (FR) for the girls.
Professor Cummer also sees potential in the field of sound dampening or diffusion: "You can engineer something that has a flat surface but reflects sound like a bumpy surface," he notes.
Paul Geluso and programmers at Harvestworks have created a new 3-D sound object, or "diffusion speaker system," as Harvestworks Executive Director Carol Parkinson calls the new invention.
If you find yourself as the last player on your team, with one on theirs and the bomb planted (with more than 10 seconds remaining), you may want to consider that the other player is hiding; waiting for the bomb diffusion sound.
The diffusion of sound created by reflections from those objects, acousticians agree, prevents a nasty acoustic "hardness" or "glare" that smooth surfaces can generate.
Away went the curved side balconies and curved back wall that Mr. Harris had identified as obstacles to the proper diffusion of sound.
