TL;DR: "120 dB at 10 Hz is already dangerous" [Elektroda, tomaszo, post #551916] Prolonged 3-10 Hz exposure can trigger organ-resonance; one lab study found 22 % of subjects reporting nausea above 110 dB (Inukai 2015). Why it matters: apartment subwoofers, heavy traffic or even ventilation ducts can leak infrasound that unsettles sleep and concentration, yet most meters ignore anything below 20 Hz.
• Human-organ resonance band: 4–25 Hz [Elektroda, zbych m, post #541785] • Wavelength at 10 Hz ≈ 34 m, so full pressure builds only in large spaces [Physics Handbook] • WHO recommends ≤ 110 dB for 20 Hz tones to avoid vestibular effects [WHO, 1999] • Typical 15" home woofer falls 12 dB by 20 Hz; output below 15 Hz is < 80 dB SPL [Czerwinski 2000] • Rotary sub-systems rated 1–30 Hz, > 115 dB SPL cost ≈ $25 k [Elektroda, Medeis, post #3283239]
