Where
SPL=sound pressure level, decibels (db)
P=sound wave pressure, newtons/meter2
Pref=reference pressure or hearing threshold, newton/meter2
IL=intensity level, decibel (db)
I=sound intensity, watt
I0=reference intensity or least audible sound level, watts
PAV=average power, watt
NPL=noise pollution level, decibel (db)

Notes:
- Usually, I0 is set to 10-12 watts
- Usually, Pref is set to 0.00002 newtons/meter2
