What is 2D diffuser?
STEALTH Diffusers are 2D (two-dimensional) diffusers that scatter sound energy horizontally and vertically, thanks to the random elevations and varied patterns of STEALTH’s surface. STEALTH Diffusers expand the listener’s sound field for a more enveloping experience.
How do QRD diffusers work?
Science behind diffuser The QRD reflects the energy into the room. But contrary to the flat and straight reflective surfaces, which reflect energy, the diffusers diffuses the sound to various directions and in different time thanks to the wells of varying depths.
What is sound diffuser material?
Diffusers may be manufactured from molded plastic or E-Glass and may be wrapped or covered in various fabrics. Sound diffusers are often used in combination with other materials such as sound absorbers, bass traps, ceiling clouds or other provisions to achieve the desired results for the application.
Where do you put the QRD 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.
Where should you put a diffuser in a room?
Do wood sound diffusers work?
Before you ask “do wood sound diffusers work?” you can rest assured that they do. But to build a good skyline diffuser, it’s important to be familiar with what’s known as a sound diffuser calculator or an acoustic diffuser calculator.
What are the different types of sound diffusers?
There are two main types of acoustic diffuser, skyline and quadratic. They rely on similar mathematical principles to diffuse sound. One uses wells or troughs; the other uses different tower heights.
What is QRD 2D?
Bluetone QRD 2D is a classic two-dimensional QRD diffuser that provides high quality acoustic diffusion from about 700 Hz to 2.5 kHz. The design is based on the quadratic residue sequence for the prime number 11. It is a 2D hemi-disc diffuser, meaning it disperses reflections by spreading sound energy in the horizontal and vertical plane.
What is a QRD diffuser?
Traditional QRD Diffuser, which can be used as an alternative to absorption to solve acoustical problems such as comb filtering and slap echo. Dimensions: 50x50x11.5 cm
What is a quadratic residue diffuser?
Raising a number to a power is known as a Quadratic operation. Applying the modulus operator divides a number by the modulus and only keeps what’s left over, known as the Residue . This explains why the design is called a Quadratic Residue Diffuser, or QRD diffuser for short.
What is the design of the 11 disc diffuser based on?
The design is based on the quadratic residue sequence for the prime number 11. It is a 2D hemi-disc diffuser, meaning it disperses reflections by spreading sound energy in the horizontal and vertical plane.
