Thus, if a "Sone 363" product exists, it is almost certainly a heavy-duty industrial blower with a model number like "Sone-363," where "363" might denote cubic feet per minute (CFM) or motor horsepower (e.g., 3.63 HP). The actual acoustic output would be a secondary spec. Regulatory Standards – OSHA (USA) sets a permissible
| Effect | Threshold (approx.) | Relevance to 363 Sone | |--------|---------------------|----------------------| | Temporary Threshold Shift (TTS) | >85 dB for >8 h | 363 sone (≈125 dB) causes TTS within minutes. | | Permanent Threshold Shift (PTS) | Cumulative exposure >100 dB | A single 363‑sone event can produce irreversible damage if the duration exceeds a few seconds without protection. | | Acoustic Trauma (ruptured eardrum) | >150 dB SPL (instant) | 363 sone is below the rupture threshold but can cause severe pain and disorientation. | | Startle and Stress Response | >110 dB SPL | The autonomic surge (adrenaline, heart‑rate spike) is typical near 363 sone sources. | | Masking of Speech | >70 dB SPL | At 363 sone, normal conversation is impossible without shouting or electronic amplification. |
Exposure to 363 sones (125 dB) is illegal without a hearing protection zone. In the US, OSHA 29 CFR 1910.95 mandates that any sound exceeding 115 dB (approx. 200 sones) requires a hearing conservation program. At 125 dB, administrative controls (job rotation) must limit exposure to <15 seconds per 8-hour shift.
