Schall Intensity Level Rechner — Formel
## Sound Intensity Level
The decibel scale expresses sound intensity relative to the threshold of human hearing.
### Formula
**L = 10 log10(I / I0)**
- *I* = sound intensity (W/m2)
- *I0* = 10^-12 W/m2 (reference threshold)
Every 10 dB increase corresponds to a tenfold increase in intensity. Normal conversation is about 60 dB; a rock concert about 110 dB.

Lösungsbeispiel
Sound intensity of 0.001 W/m2.
- L = 10 log10(I / I0)
- L = 10 log10(0.001 / 1e-12)
- L = 10 log10(1e9)
- L = 10 * 9 = 90 dB
