Acoustic Foam vs Semi rigid fibreglass
Posted on February 8, 2010
Happy new year, my first post for 2010! I often read in forums (Gearslutz etc) ongoing arguments about polyurethane bass traps (such as ours) versus semi rigid fibreglass. The data below makes for interesting reading. This comparison was performed a few years ago at the Riverbank acoustic laboratory in the US. It compares a large Auralex trap (polyurethane foam) with a semi-rigid fibreglass trap of the same volume, and a flat fibreglass corner design. The polyurethane foam edges out the fibreglass in a close run race!

Interesting.
To which standards were the tests and results based upon.
Cheers.
