What is quadratic residue diffuser?

A quadratic residue diffuser such as the Razorblade is a device designed to break up directional sound waves and reduce powerful first order reflections, standing waves and flutter echo. It is an excellent complement to sound adsorption because it does not remove energy like acoustic panels.

What is quadratic diffusion?

Quadratic diffusion is a powerful tool to manage room boundary reflections. It is a tool that can take the reflection and “break” it down into smaller “reflections” that can then be spread out into the room into vertical and horizontal directions without any change in the signals time signature.

What does a QRD diffuser do?

A QRD diffuser comprises wells of different depths, causing a mixture of phase shifts that diffuse reflected sound. They are used to control reflections in the listening environment, particularly from rear walls and first-reflection points.

How do you make your own diffuser?

How To Make Your Own Room Diffuser

1. Add 1/4 cup of baby oil, or any other unscented or lightly scented oil such as almond, mineral, safflower, or jojoba oil into to a small bowl.
2. After carefully add 20 to 25 drops of your favorite essential oil scent to the bowl.
3. Find a small vase or glass bottle for your room diffuser.

Where do you put the acoustic diffuser?

Generally speaking, the best place to put sound diffusers are at the primary reflective points in your listening room. This is the place where the sound from your speakers will first hit a wall or surface to reflect back.

What type of surface is used as an acoustic diffuser?

Most often, an absorptive panel of fibrous material (fiberglass, cotton, mineral wool, wood wool) is placed in a room on hard, flat sound-reflective surfaces to reduce the energy “bounced” back into the room.

Where do you put the QRD diffuser?

Sound diffuser Positioning The optimal position in a room is usually behind the listening position or behind the loudspeakers on the right or on the left side. Of course, a wider room will provide wider diffuse area.

Where should a sound diffuser be placed in a room?

How does a quadratic residue diffusor work?

The quadratic residue diffusor or Schroeder diffusor (Schroeder was the scientist who pioneered the development) is typically a box made with a number of wells of different, carefully chosen depths. As a sound wave strikes the irregular surface, instead of bouncing off it like a mirror, it bounces out of each well at a slightly different time.

How is the depth of a quadratic diffuser determined?

Quadratic Diffuser. A quadratic diffuser is a series of wells or troughs that are of different depths. Each well depth is based on quarter wavelength calculations and the well width is based on half wavelength.

How does a quadratic sound diffuser reduce reverberation?

A quadratic diffuser uses wells or troughs of calculated depths and widths, also in a set pattern, to predictably control the diffusion of soundwaves in an even pattern. Made out seasoned scrap 2×4 pieces, this diffuser not only decreases reverberation but also looks like a piece of artwork, which it is!

What’s the difference between a QRD and a 2D diffuser?

A 2D QRD is slightly different from a QRD as you glue the towers directly to a side-less backboard. If the diffuser is for a smaller space then a two-dimensional QRD is a suitable option. This diffuser is technically a 2D QRD but is a popular type within its own right.
