Corner bass traps???

Hello I wanted to know if anyone has done a comparison on corner bass traps made with big triangles of oc703 built in to the wall against the same idea but instead of triangles a layer lets say 6 inches then an air gap.

I've seen them fairly large in big pro studios they must be a few feet thick at least at what frequency do these go down to,

Is there a frequency to thickness chart

Thanks

Are you just talking about a 6" panels straddling the corner? Sure many people of tested that. Filling the corner will just reach lower frequencies.

Frequency to Thickness

You can predict absorption. Note this calculator will do a single individual of incidence (try 45-50.....up to 85) and also a diffuse reverberant field.

Porous Absorber Calculator

Here's the Gas Flow Resistivity numbers you will need.
Common Gas Flow Resistivity numbers.

Many will disagree about the depth needed for 'useful' absorption. Most will agree that 1/4 wave does pretty much 100%
Studio designers often use a figure of 1/10 of wavelength to achieve 'significant' absorption. (about 85%)
