QRD diffuser
is a sequenced grid that is calculated strictly according to the QRD theoretical formula. Its groove depth and width can produce uniform diffuse reflection under omnidirectional and multi-angle incident sound conditions. It makes the human voice more supple, the high frequency becomes more full, and makes the small space have the effect of the hall.
Compared with flat reflectors, QRD diffusers can effectively avoid acoustic focusing. When the sound wave passes through the plane reflector, all sound energy will be reflected in the same direction, its reflection direction is fixed, the direction of reflection depends on the location of the sound source. And when the sound wave is reflected by the surface of the QRD diffuser, sound energy will be scattered and reflected in different directions, and have different phase differences.
These irregular vibrations of uniform energy can subjectively create a sense of space for the human ears. At the same time, it will increase the brightness of the sound when it is diffused in the middle and high frequencies. Its reflection direction is roughly a semicircle, and the sound energy will be averagely diffused. Another effect of QRD diffuser is when the reflective surface is a QRD diffuser, because sound waves diffuse in a semicircular direction, there are countless reflection paths of different frequency bands converge at the listening position, and so forth, there are countless convergence points of the same nature, this will invisibly expand the listening area.
Detailed Images
QRD diffusers can be used not only to dissipate sound energy, play the role of preventing echo and standing waves. At the same time, it can improve the brightness of the sound. Appropriate addition of QRD diffuser on the early reflection path reflects high frequency near 2K can increase brightness, and can significantly improve the sound quality if cooperate with sound absorbing materials.

FAQ
1.How can you guarantee the quality?
We have a modern management system. Take strict selection for upstream suppliers to insure the basic material to be good quality.
And we pay more attention to production technology and staff training, so that the defective rate is less than 1% of each
products, save cost at the production line. When the productions are ready, they would be sent to the package workshop, put in
carton with foam between each panel to avoid the friction and damage.
2.Can you offer sample?
Yes, we can offer standard samples for free, and customization is available.
3.Do you accept customization?
Yes, we can support our clients with OEM, so that it can be easier to open the local market and build a long-term partnership
between us.
4.How long is the lead time?
Normally 10-25 days upon receiving the deposit, base on the quantity 1,500 SQM
5.Can you assist for installation?
Yes, we can arrange to assist in installation if needed.
6.Do you have CE certificate?
Yes, we do. We have shipped many goods to European countries.
7.What are the factors of influencing the NRC?
Perforation rate, gap between the wall and panel, the density and thickness of the glass wool, etc. All these factors will effect
NRC.
8.What's the difference between normal panel and acoustic panel?
Acoustic panel also called soundproof panel which is designed according to the law of soundproofing. There are mainly three
functions of acoustic panel. Sound absorbing, sound diffusing and sound insulation, with respect to a specified sound source and
receptor: increasing the distance between source and receiver, using acoustic panel to reflect or absorb the energy of the sound
waves, using damping structures such as acoustic panel, or using active antinoise sound generators.
9.How about the capacity of your factory?
We can produce 500000sqm acoustic materials per year.
10.How to pay?
You can pay by western union or T/T. Cash will be ok if we do business face to face.
