The decibel level of a sound having an intensity of 10⁻¹² W/m² is β = 0 dB
Decibel Scale
The SI unit of sound intensity is the W/m² but it is more better to measure it in decibels (dB), this is done using:
β = 10log(I/I₀)
Where I is the intensity, I₀ is the reference intensity = 10⁻¹² W/m²
For a sound with intensity of 10⁻¹² W/m²:
β = 10log( 10⁻¹²/ 10⁻¹²) = 0 dB
