The 125Hz Problem Nobody Treats — Why Your Meeting Room Still Sounds Like a Cave

Meeting rooms pass RT60 tests at 500Hz and still sound terrible. The culprit is 125Hz bass reverberation — standard acoustic foam panels have α ≈ 0.05 at 125Hz and do almost nothing. Here is the calculation that reveals the problem and the bass trap specification that solves it.
