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.
The 15 Acoustic Design Mistakes Architects Make — And the Standard Clauses That Prevent Them
15 specific acoustic design errors that architects commonly make, each matched with the exact standard clause that would have prevented it. Covers NRC misuse, low-frequency neglect, parallel wall flutter echo, soundproofing vs treatment confusion, HVAC noise, glass overuse, ceiling-only treatment, room modes, Sabine misapplication, occupancy effects, and flanking transmission. Includes worked examples and remediation costs.
