Acoustic Treatments - Diffusers
Diffusers are hard surfaced acoustical treatments with either irregular surfaces that break up and scatter sound waves in multiple directions, or convex curved surfaces to gently split frequencies and deflect them in multiple directions. Diffusers improve the surround field creating a more immersive experience for the listener. In their natural state, diffusers give an appearance befitting a recording studio rather than a home theater. For this reason they are generally hidden behind an acoustically transparent fabric.
Acoustic Innovation Diffusers come in two product types and two colors:
  • Randomizing (Black or White)
  • Radial (Black or White)



What is the best method of making diffusers more decorative in a home theater?
Both styles of diffusers can be painted using standard household paint. Upon request, diffusers can be integrated behind fabric in a wood frame that can then be hung directly on a wall like our Element or Harmony Panel series. In other applications, diffusers may be adhered directly to a wall underneath a fabric stretch wall solution like our Concerto Wall System.
How are diffusers different then reflective panels from the Harmony family?
Diffusers provide a similar benefit to reflective panels, but can be more effective as the diffusers surface breaks up sound waves and scatters them in many directions, while reflective panels cast sound into a narrower and more direct angle. Both are used to enhance the surround field, assisting the illusion of envelopment.
Could I treat a full room with diffusers?
It's important to recognize that diffusers have a specific task in the theater and should not be used in critical areas such as first reflection points as they provide little sound absorption. For this reason its important to use a balance of acoustically absorptive, reflective and diffusive products to provide ideal acoustical control in your theater.

More about Absorptive Panels
Sound is a wave, and just like a pebble in a pond produces concentric waves on the surface of the pond, the speaker (also known as the driver) produces spherical pressure waves. Some of these are direct sound waves. And like the pebble in the pond, some waves also radiate in other directions. This sound reflects off the room’s hard surface boundaries, which create early and late reflected waves. The difference in timing and strength of these two paths, the direct and reflected sound waves, create what is called reverberation. The amount of reflected surfaces and size of the room all have an effect on the reverberation time.
Panels at the first reflection points allows significantly more sound absorption than an untreated surface can provide. By reducing the delay and strength of the reflected sounds we are able to lower the reverberation time, allowing your ear to experience a crisper and clearer perception of the movie track, in particular the main dialogue.
Just like excess reflection, excess absorption in a theater will result in poor sound. Anechoic chambers- where loudspeakers are tested- are designed to have complete absorption for test purposes. This is often called an acoustically DEAD room. For this reason, reflective panels exist.
