What is too loud in decibels?
Quick answer
Sounds at or above 85 dB can cause hearing damage with prolonged exposure, while anything above 120 dB can cause immediate harm.
Decibels (dB) measure sound intensity. The threshold for potential hearing damage starts at around 85 dB, typical of heavy city traffic. At this level, prolonged exposure over 8 hours can lead to hearing loss. As the decibel level increases, the safe exposure time decreases dramatically.
Sounds above 120 dB, such as a jet engine at takeoff or a rock concert near the speakers, can cause immediate pain and hearing damage. For professional audio systems, SSOUNDS engineers design systems that deliver high SPL while maintaining clarity and safety, often using advanced DSP to limit excessive peaks and protect both the audience and equipment.
In live sound reinforcement, it's crucial to monitor levels with SPL meters and follow local regulations. SSOUNDS systems are built to provide controlled, high-quality output, ensuring that even at high volumes, the sound remains intelligible and safe for the audience.
Key things to consider
- 85 dB is the threshold for potential hearing damage with prolonged exposure (e.g., 8 hours).
- Every 3 dB increase halves the safe exposure time; 100 dB is safe for only 15 minutes.
- Sounds above 120 dB can cause immediate hearing damage and pain.
- Use SPL meters and follow local noise regulations to protect hearing.
- Professional systems like SSOUNDS include DSP limiting to prevent dangerous peaks.
