Noise Damage Risk Calculator

Estimate hearing risk based on sound level (dB) and exposure time. This is an approximate estimate for educational use.

Example: 60 quiet talk, 85 traffic, 100 concert.
Choose a preset or set custom below.
Example: 75 minutes.
Reduces effective dB (very approximate).
Frequent exposure increases overall risk.
Indoor spaces can increase intensity at your ears.
How we calculate

We estimate a “safe time” using a simplified 85 dB for 8 hours reference and a 3 dB exchange rate (every +3 dB halves safe time). We then compare your exposure to that safe time.
