Hush from Sense & Sound used our diffusers on the ceiling in a recent studio build! He mixed the large and small panels together. It looks amazing!

What are acoustic diffusers used for?
Decrease echoes! Sound diffusers are used to treat echoes and reflections. Unlike acoustic foam panels that are designed to absorb sound waves at different frequencies, acoustic diffusers are designed to scatter sound waves.
Get professional quality sound! Our acoustic panels are made for sound diffusion, not sound absorption. Absorption panels will have a dampening effect while diffusion panels will maintain a more lively sound. These diffusers are used for high frequency (above 2000 Hz) diffusion. Diffusers are often used in combination with sound absorbing panels and bass traps in order to get the desired sound in your room.

Installation
How to install acoustic diffusers?
These lightweight PVC acoustic diffusers can be mounted for permanent or temporary use. Adhesives sold separately. Installation is a breeze.
Permanent adhesives

Where to place acoustic diffusers?
Acoustic diffusers are placed at the reflection points in your room.

For a recording studio the most common reflection points for diffuser placement are at the back wall or on the ceiling between the listening position and the sound source.
