Darker bars (100–315 Hz) indicate the low-frequency range where thin foam underlayments perform weakest.
Note on Flanking
The CENSEO report states flanking transmission was not fully evaluated. The AIIC 51 result should be treated as a minimum value — actual performance may be higher once flanking paths are accounted for.
