A minimal, always-on web page that emits a single, ultra-stable, analog-style low-frequency hum (58–65 Hz), generated in-browser with Web Audio API, adjustable only by subtle slider (±2 Hz), with optional gentle pulse modulation—designed to coexist with wakeful alertness, not override it. r/anxiety | QUOTE: “My therapist said ‘grounding’—so I tried 5-4-3-2-1. It failed. Because my hands were shaking and my breath was too fast to count. What worked? Opening a YouTube video of a 1970s HVAC unit running in a library basement. No narration. Just that deep, unbroken 62Hz hum. I slept three hours after.”
