Sound pressure level (SPL)
SPL is a ratio of the absolute sound pressure to a reference level, usually the Threshold of Hearing, or the lowest intensity sound that can be heard by most people. SPL is measured in decibels (dB) due to the broad range of intensities we can hear.
Formula:
SPL = 20 * log (P/Pref)
Where:
SPL - is the sound pressure level in dB
P - is the sound wave pressure, measured in pascals
Pref - is the reference value of sound pressure, typically assumed to be equal to 0.00002 Pa
Sound intensity level (SIL)
Sound intensity is defined as the sound power per unit area, typically measured in the air at a listener's location. The basic units are watts/m² or watts/cm².
Formula:
SIL = 10 * log (I/Iref)
Where:
SIL - is the sound intensity level in dB
I - is the sound intensity in watts per squared meter
Iref - is the reference value of sound intensity, typically assumed to be equal to 10⁻¹² W/m²
