# Sound pressure and decibels
# Scope: RMS pressure level relative to 20 micropascal; airborne sound.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

pressure = 0.02 Pa
reference = 20 uPa

levelDb := 20*log10(pressure/reference)

check sound level budget in dB: levelDb <= 70

scenario alternative: pressure = 0.016 Pa
