FreqWave EQ

The 31 user comments (primarily from HackerNews) reveal significant concerns about a browser-based 40Hz light and sound therapy tool. Multiple users reported PERMANENT or lingering monitor damage after running the flashing application for as little as 15 seconds — one user stated 'This just fucked my 2k$ 4k LG display' with persistent flickering even after reboot. Others noted ghosting artifacts that required power-cycling or built-in LCD conditioning to resolve. Technically, users identified that the tool uses requestAnimationFrame for timing, which produces significant jitter and cannot reliably achieve 40Hz on standard 60Hz monitors (effectively outputting 30Hz instead). Multiple users suggested hardware alternatives: $5 microcontrollers with PWM output, 555 timers, Pi Pico, or distributing as a video file for 120Hz-capable displays. Several commenters questioned the scientific validity, noting the original MIT research used physical vibration via a 12-inch subwoofer (not just light), was conducted on mice, and that the underlying cause of Alzheimer's remains unknown. One user noted the tool worked 'quite well on an iPhone in a dark room with brightness turned up.' A separate set of Reddit comments discussed an unrelated EDC (everyday carry) tech setup including iPods, e-readers, and synthesizers — these appear mismatched to this product entirely.
