Use Your Phone Like an Acoustician
Free and paid apps can approximate A‑weighted levels, showing typical baselines and disruptive peaks. Log readings during rush hour, meetings, and quiet moments. Pair results with a simple clap test and voice check. Numbers make conversations objective, easing buy‑in for door seals, panels, or desk moves. Even if absolute accuracy varies, trends are invaluable, turning intuition into shared evidence and momentum toward meaningful, lasting calm.
