Noise Level Reference – Convert Decibels to Everyday Sound Examples
The noise level reference shows decibel levels compared to familiar everyday sounds. Enter a decibel value or select a sound source to see what it compares to.
The tool covers the sound scale from silence (10 dB) to jet engine proximity (140 dB). You'll also see safe exposure times for different sound levels from a hearing protection perspective.
What sound level damages hearing?
85 dB is the threshold above which long-term exposure damages hearing. Workplace noise may exceed 85 dB only briefly — the 8-hour exposure limit is 85 dB. 100 dB (e.g., concert) damages hearing in just 15 minutes without protection. Hearing damage is permanent — use hearing protection in environments over 85 dB.

The tool compares decibel levels of different sound sources and helps visualize the differences in sound intensity.
- See typical sound sources' decibel levels in a clear comparison.
- You can compare traffic noise, music listening, and machinery sound levels.
- The tool helps assess when hearing protection is needed.
The decibel scale is logarithmic, meaning even a small numerical difference can represent a large change in sound intensity.
- A 10-decibel increase practically means double the perceived loudness.
- Continuous exposure over 85 dB can damage hearing over time.
- Brief loud sounds (e.g., fireworks) can cause immediate harm.
Actual noise exposure depends on distance, duration, and environment.
- The presented decibel values are typical averages – actual values vary.
- Hearing damage is permanent, so prevention is important.
- Precise noise exposure measurement requires a dedicated measuring device.
