Sound Intensity Level Calculator

Q: How is sound intensity level calculated?

It is calculated using the formula: SIL = 10 * log10(I/I0), where I is the sound intensity and I0 is the reference intensity.

This calculator helps you determine the sound intensity level based on input values. It's designed for students, engineers, and acoustics professionals who need precise calculations.

Data Source and Methodology

Tutti i calcoli si basano rigorosamente sulle formule e sui dati forniti da scientific journals and acoustic standards.

The Formula Explained

SIL = 10 × log₁₀(I/I₀)

Glossary of Variables

I: Sound intensity in watts per square meter (W/m²).
I₀: Reference sound intensity (1×10^-12 W/m²).

How It Works: An Example

To calculate the sound intensity level for a sound intensity of 0.01 W/m², use the formula SIL = 10 × log₁₀(0.01/1×10^-12), resulting in 100 dB.
