The Roxul acoustical performance is similar to the Owens Corning and Johns Manville products, but it is softer and has a less regular shape. My prototype panels were built with the Roxul RHT 80 insulation, which is the least expensive sound absorption material that I have found. The essential elements of a sound absorption panel include:
What follows are explanations, instructions, and specifications for very effective sound absorption panels. I may annoy a few people by telling you this, but you can make your own sound absorption panels for MUCH less. I have seen sound absorption panels priced as high as $12.25 per square foot! Given the large square foot area that needs to be covered to achieve a suitable home theater acoustic, this falls well outside of the average consumer’s budget. Pricing for manufactured, two-inch thick, fabric-wrapped fiberglass sound absorption panels is usually $6 to $8 per square foot.

Extreme ends of the spectrum range from traditional/classical worship spaces which are entirely hard-surfaced (great for pipe organ and choral music) to THX-certified cinemas and movie theaters which have sound-absorbing materials on all wall, floor, and ceiling surfaces.Ĭonsider which wall and ceiling reflections need to be eliminated and cover those entire areas with sound absorption treatment. The necessary quantity and placement of sound absorption material for a given space is determined by the specific type of listening functions occurring there. – For amplified music with bass and drums or cinema surround-sound use 2” absorber thickness (or greater) – For human voices, crowds of people, and speech use 1” absorber thickness For placement on drywall surfaces, the following rules of thumb should be helpful: Therefore, when choosing an acoustical material, consider the frequency content (tonal spectrum) of sound that you seek to absorb.
A thicker panel will more effectively absorb a longer wavelength (lower frequency) of sound. These material types are mostly differentiated by their visual appearance.Īn important consideration for any sound absorption panel, though, is thickness.

Feel free to compare Sabine absorption coefficients at your leisure. The acoustic properties of each of these are very similar, with all of them absorbing approximately 100% of incident sound energy at mid and upper frequency ranges.
