  • Universal Acoustics foam tiles claims relatively average frequency absorbtion with NRC 0,85 and density of 30kg/m3.

  • Vicoustics foam tiles aren’t as good as other manufacturers, but they are a little more stylish. The 0,5 NRC Cinema Round tiles have a flat absorbtion above 500Hz, which is as expected. Interestingly, the MD55 Light tiles have a non-flat absorbtion. The absorbtion increases linearly with frequency. The NRC is 0,6 and density 30kg/m3.

  • Auralex Acoustics makes a few foam panels of different thickness and colours. The 33kg/m3 100mm tiles has an NRC of 1,1 and a flat frequence absorbtion above 300Hz.

  • Adam Hall is a well-renowned manufacturer providing a medium density foam absorber at 23kg/m3.

  • The Thomann t.akustik CBT-37 foam basstrap has no specification at all, but using a bathroom scale I estimate their density to roughly 20kg/m3. This makes them the lightest and cheapest traps I’ve found.

  • The Thomann t.akustik range of foam absorber tiles, are Thomann-branded, budget material. The only specification given for the HiLo tiles, is their density; At 16,5kg/m3, the material is the lightest material I’ve found, which I believe cases poor performance. It is the cheapest material, though, and probably better than nothing. They are available in different…
