Examples include:

| Effect | Threshold (approx.) | Relevance to 363 Sone | |--------|---------------------|----------------------| | | >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. |
