What is too loud in decibels?
Quick answer
Sounds above 85 dB can cause hearing damage with prolonged exposure, while anything over 120 dB poses immediate risk of injury.
Decibel (dB) levels measure sound intensity. For context, normal conversation is around 60 dB, city traffic about 80–85 dB, and a rock concert can exceed 110 dB. The threshold for potential hearing damage starts at 85 dB over an 8-hour period; each 3 dB increase halves the safe exposure time.
Sounds above 120 dB—like a jet engine at takeoff or a gunshot—can cause immediate pain and permanent hearing loss. Professional audio systems, including SSOUNDS line arrays, are designed to deliver high SPL while maintaining clarity, but operators must follow safety guidelines and use limiters to protect audiences.
Regulatory bodies like OSHA and WHO recommend exposure limits: 85 dB for 8 hours, 88 dB for 4 hours, and so on. For events, sound engineers should monitor levels with SPL meters and ensure compliance to prevent hearing damage.
Key things to consider
- 85 dB is the threshold for prolonged exposure risk (8-hour limit).
- 120+ dB can cause immediate hearing damage or pain.
- Each 3 dB increase halves safe exposure time.
- Use SPL meters and limiters to protect audiences.
- Professional systems like SSOUNDS deliver high output safely with proper setup.
