Qrd Wood Wall Ppaneling / Acoustic Diffuser Panels Square Edge Treatment

Soundproof Wooden Acoustical Diffuser Panels

Description:

A good diffusor not only changes the reflections to propagate in different directions, but does so EVENLY in all directions. Just splitting a wave to go into 2 directions doesn't do enough. We've effectively changed the concentration of the waves in a certain portion of the room. We've also effectively taken the intensity of the initial wavefront and split it among the various reflections so that each one is not only coming from a different direction, but each is also weaker and harder to distinguish but we've lost no energy in the process.

A proper diffusor also impacts the time domain. If we have the same wave and it gets reflected into multiple directions evenly, the length of the path the various waves must take to reach the listener also changes. In the world of sound, distance is time. For ease, we can say that 1 foot equals approximately 1ms of time. So, if we've changed the path into say 8 different paths (in reality, there are many paths but we'll look at 8 just for ease of understanding), each one ideally with have a different path, which means that they'll arrive at 8 different times. Again, we're diluting the concentration of sound but this time in the time domain instead of spatially. In addition, these different path lengths cause differences in the number of reflections and the amount of air the wave passes through which will cause each reflection to have a different intensity (more dilution in yet another domain intensity).

Advantages:

D30 solid wood diffuser can be used to diffuse the sound energy in a stereophonic manner, prevent echoes and standing waves to realise diffusion in all the directions, and improve the articulation of sound and the sense of space.

Acoustic Diffuser adopt the QRD diffusion principle that is quadratic residue theory.
The sound energy enters the different depth of diffuser and was reflected at diffident time, so the peak and the bottom spectrums become smoother and to make a more neutral and balanced listening space.
Our acoustic diffuser is widely used in auditorium, multi-function hall,recording studio,home theater and any other places with high acoustic requirement.

Technical information:

Material details:

Wood has a true natural resonance response and because this diffuser uses over 100 partitions per 50 cm (!), sound will resonate in a natural unique way. Some big companies are selling useless, unworthy diffusers very light or without enough partitions for their size, or enough depth that comes in a very nice package with the brand beautifully marked on the cardboard.Diffusers that are made of plastic or styrofoam or even made of wood – but with just a few very large wood wells (easy to build) – have poor acoustic effect.

Application:

opera houses, music halls, private theatres, recording studios, HIFI listening rooms, etc. with high-end indoor sound quality requirements for building acoustic decoration
