Find how sound intensity changes with distance. Input values to get precise results on sound measurement and intensity drop over distance.
| Initial Distance (m) | Final Distance (m) | Initial Decibel (dB) | Calculated Decibel Change (dB) |
|---|---|---|---|
| 10 | 20 | 80 | -6.0 |
| 5 | 10 | 85 | -3.0 |
The decibel change due to distance is calculated using the formula:
ΔdB = 20 * log10(d1 / d2)
Where:
Input the initial sound intensity in decibels and the corresponding distance. Then, enter the final distance. The calculator will return the decibel change between the initial and final distances based on the formula above.
