Absorber Panel Air Gaps

Hi All!

Is a 75mm deep absorber more or less effective than a 50mm with a 25mm air gap?

Also by extension is a corner bass trap more or less effective by filling the entire corner with absorbing material vs having an air gap behind a panel of absorbing material, with the same frontal area.

Thanks!

Assuming proper material selection for the depth, full fiber fill is better. 200mm is considered minimum depth for porous absorbant.

The will both cover down to the same frequency, but the 75mm one will be a bit more effective, and will have smoother absorption (slightly flatter). And as Jason said, 75mm isn't very much... 200mm or more is good.

Both will work the same with the proper materials. The BBC has built absorbers with to 6:1 cavity to material thickness.

The BBC R&D has budgets resembling small countries' budgets. Thank you Eric Desart for that line.
