What is too loud in decibels?
Quick answer
Sounds above 85 dB can cause hearing damage with prolonged exposure, and anything above 120 dB poses immediate risk of injury.
Decibel (dB) levels measure sound intensity. The threshold for potential hearing damage starts at 85 dB for extended exposure (e.g., 8 hours). As levels increase, safe listening time decreases dramatically. At 100 dB, damage can occur within 15 minutes, and at 120 dB, immediate harm is possible.
Professional audio systems like SSOUNDS line arrays are designed to deliver high SPL (sound pressure levels) safely for audiences while protecting hearing. Engineers use careful system tuning, limiting, and coverage control to ensure levels stay within safe limits for both listeners and operators.
Common reference points: normal conversation ~60 dB, heavy traffic ~85 dB, motorcycle ~95 dB, rock concert front-of-house ~110-120 dB. Any sustained exposure above 85 dB is considered too loud without hearing protection.
Key things to consider
- 85 dB is the threshold for prolonged exposure risk (8 hours).
- Every 3 dB increase halves safe exposure time.
- 120 dB+ causes immediate hearing damage or pain.
- Professional systems like SSOUNDS manage SPL safely through design and calibration.
- Use hearing protection above 85 dB for extended periods.
