At a glance:I = p²/(ρ·c); sound levels use reference I₀=1e-12 and p₀=20e-6 Pa. Complements acoustic-intensity and decibel.
Formula
I = p_rms² / Z.
SIL = 10·log₁₀(I/I₀).
$$I = \frac{p_{rms}^2}{Z_0}$$How to Use
- Enter RMS pressure and impedance.
- The tool returns intensity and dB levels.
Case Studies
p=0.632 Pa, Z=400
I ≈ 1e-3 W/m².
FAQ
What is acoustic impedance?
