![]() Cut a French cleat in back to provide greater support for the heavy piece of artwork. Didn’t use a backer board due to concerns seasonal expansion would cause sections to split. One side will look like a skyline, the other like a butcher block. Use a good construction adhesive that won’t leave a gap between blocks. Lay out each row in a random pattern using the same number of each block height per row. Sand each piece smooth, including the ends remember to keep each edge square!Īssemble the pieces on a solid (and strong) flat surface. ![]() Cut the lengths into an equal number of 2”, 4” & 6” pieces. ![]() Made out seasoned scrap 2×4 pieces, this diffuser not only decreases reverberation but also looks like a piece of artwork, which it is! Trim the 2x4s, so the beveled corners are gone. Quadratic Residue Diffuser (QRD) DiffusersĪ 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. The pattern of the blocks makes it look like a city skyline. Skyline diffusers use solid square cut blocks of calculated length arranged in a set pattern to scatter soundwaves evenly. Skyline diffusers take up more space and are heavier than QDR diffusers. They are basically the inverse of the other. One uses wells or troughs the other uses different tower heights. They rely on similar mathematical principles to diffuse sound. There are two main types of acoustic diffuser, skyline and quadratic. Combined and positioned correctly, they produce better harmonics and make a room sound bigger. If the wells are oriented horizontally, there is a vertical diffusion of sound, while a vertical orientation creates a horizontal diffusion. The orientation of the pattern of the wells is also important to the diffusion. If the wells or towers are not correctly calculated and constructed, they won’t scatter the waves evenly, which will cause an uncomfortable listening experience. This will impact the timing, direction, and intensity of soundwaves making for a more enjoyable listening experience. By controlling the two dimensions of horizontal and vertical, wavelengths from low to high range can be diffused in a controlled, predictable manner. The depth or height of the well or tower is derived from the quarter wavelength rule, and the width is a half wavelength. It uses wells or towers in a pattern of differing depths, heights, widths, and spacing calculated to create an even soundwave scattering. Instead of creating confusion about diffusion, understand that a diffuser scatters soundwaves over a 180-degree angle. How a Sound Diffuser WorksĪ diffuser is designed based on a mathematical formula involving prime numbers. Diffusers are a great addition to any room to improve sound and control resonance concerns. They can be mounted on walls opposite speakers and even on ceilings. It can even make a small room seem large. To help give sound life in a room a diffuser absorbs some sound, but treats echo and scatters resonance around a room, bringing it to life, just like nature does. A diffuser also helps with standing wave build up and comb filtering and can be designed to address any frequency spectrum from a very low range to the high range. It allows for a more natural softening and termination of sound reverberation, so a room doesn’t feel devoid of sound life. The different surface heights of a diffuser are designed so that a sound wave from any direction will hit and deflect evenly in multiple directions. We can hear a songbird from 100 yards or more away without ever seeing it, yet with all the bounce and reverberation, we can often identify the species, direction, and distance. Our ears pick up sound waves that have been reflected off numerous surfaces, like trees, rocks, and even buildings. What’s a Sound Diffuser?Ī diffuser in a room does to sound what nature does naturally in the outdoors. I put together this list of 16 DIY sound diffuser panels together, along with free plans, to help you and some friends out. You can spend hundreds of dollars on diffusers, or you can make DIY sound diffusers for a whole lot less. While deaden some sound has merit, it makes the harmonics sterile or off. They are so busy absorbing sound, echo, and trapping base noise in their games or media rooms, and elsewhere that they often make it worse. Many of my friends are spending big money on soundproofing when a DIY sound diffuser would be better.
