Why do we need acoustic diffusers?
Absorbers absorb, diffusers scatter the sound waves reaching their surface. If we use purely absorbers in a room, we can overdamp it which makes the listening to music, watching movies or studio work unsatisfactory.
Therefore, reflecting sound waves should be treated some other way too: reflection points should be covered thus we won’t hear echo coming from another point with phase delay. Diffusers scatter the incoming sound energy into smaller pieces of energy: we get a clearer sound image, increased soundstage, sharper, more precise sound.
What does NOT work as a diffusers?
One should not cover the entire room with diffusers, they must be used at the targeted, proper reflection points. It can be best determined following an acoustic measurement.
By no means Styrofoam or foam can act as a diffuser if we cover all the walls with them since due to their material composition, they are unsuitable to scatter the sound in a proper way.
What sort of materials are Perfect Acoustic diffuser made of?
We use exclusively dense and high specific weight hardwood to produce our diffusers. It is important to know that the application of our diffusers is different depending on the type of room it is used and the purpose of the use.
Our company has a great deal of experience in setting up the diffusers in order to achieve the best result. We offer a wide variety of diffusers which are ahead of our competitors both in terms of aesthetics and performance.
Diffuser as home furnishing
We are aware that besides the acoustic impact, aesthetics is also an important consideration. During the production of our diffusers we pay a special attention to the individual needs: our products can be ordered in different colours and patterns, even in custom sizes in order to fit the room where you intend to use them.
The result achieved with our diffusers
Diffusers scatter the sound waves reaching their surface therefore if applied at proper places they can increase the sense of spaciousness. Applying them at proper places one can enjoy the:
cleared sound image
clarity of human voice
If it’s too late to plan
From an acoustic point of view, it would be ideal if acoustic planning and then construction were carried out during the construction of the properties. But unfortunately this is very rare. Thus, in almost all cases, buildings need to be retrofitted and repaired to achieve optimal sound. Ordinary building materials cannot absorb or scatter sounds evenly. The biggest acoustic problems are caused by rattle echoes, interferences, standing waves. We recommend bass-absorbing panels to control the accumulating bass. However, other types of products are needed to handle the mid and higher frequencies. Diffusers reduce echoes by scattering sound waves coming to their surface in smaller directions, over the entire bandwidth, into smaller parts.
You don’t have to absorb all the sounds!
Unlike the sound-absorbing elements, the diffusers do not absorb all the sound energy, they preserve the purity and liveliness of the sound. They distribute the sound energy in the room. They increase the sense of space, the ringing time of the sounds is exactly the same in all parts of the room, and also in the full bandwidth. Diffuser panels thus capture the energy of sounds and scatter it more evenly throughout the room.
Flawless sound quality is ensured by the balanced harmony of direct and diffuse sound field. In sound recording studios, the acoustic correction is even more important, so that the recorded music or other sound material will sound perfect later, even in another room!
The role of furniture:
Although walls, ceilings and all other home furnishings are diffuse and sound-absorbing surfaces, due to their structure they are almost only able to absorb high-pitched sounds, they reflect deeper sounds in one direction, creating unpleasant echoes. If only broadband sound absorbing panels are used, the sound becomes unenjoyable due to over-attenuation. The irregular surface of the diffusers, with different depths, is designed together with accurate acoustic measurements, the sounds are scattered in all directions, thus continuously reducing the energy of the sound.
Panels of this type are best placed in sound recording studios, home cinema rooms and concert halls. The appropriate number and location of diffusers depends on the size, shape and capabilities of the room. Reflection points can be determined by acoustic measurement. These points should be covered with diffusers.
Diffusers should be used in conjunction with bass sound-absorbing acoustic panels for perfect acoustics.
Importance of material use
A very important aspect is the material of the elements used to improve the acoustics! Smooth, hard wall ceilings and glass and tile surfaces are unable to absorb sounds, so they bounce back and forth between surfaces. Acoustic panels can be made of laminated furniture board or real wood. Hard or medium-hard, flexible wood materials have extremely effective sound-absorbing properties due to their specific gravity and density. Plywood, pine, oak or black walnut materials not only perform outstandingly in their function, but also represent premium quality with their demanding and aesthetic appearance. Styrofoam, plastic sponges, egg boxes are absolutely unsuitable for acoustic treatment of a room!
Easy to fix!
Fixing diffusers does not require specialist or DIY science. They can be easily fixed to the wall with the help of picture hangers and screws, or they can also be requested with folding legs if they are placed on the floor.
