three “resonance of silence” concepts, packaged as charges. no tone can make a space silent — cancelling sound needs a microphone and an inverted copy of that exact noise at your ear. each charge says what it really does.
infrasound interferenceELF · brainwave18.98HZ
conceptanecdotal · 1998
really: sits at the very edge of hearing; phones, laptops and headphones barely reproduce it. the “ghost frequency” comes from one engineer's report. loud subwoofer output strains drivers and can cause unease.
room resonancePEMF · research175HZ
conceptreal physics · room modes
really: your room's dimensions set its resonant frequencies. playing one makes it boom louder in some spots and nearly vanish in others — nodes, not silence. enter your room to find its modes:
auditory saturationLRAD2500HZ
concepthearing hazard
really: hearing is most sensitive around 2–5 kHz. “silence by saturation” is temporary threshold shift — the first stage of noise-induced hearing loss. armed at 20 % volume; keep it quiet and brief.
