Sound Pressure Level Calculator

I want to calculate
Sound Pressure(P) = P
Reference Pressure(Pref) = P
Sound Pressure Level(SPL) = Db
 

Sound pressure level (SPL) to measure the effective sound pressure of a sound relative to a reference value. The uniot of SPL is decibels (dB).

Sound Pressure Level formula

Sound Pressure Level:
SPL ＝ 20log10(P/Pref)

where, Pref = Reference Pressure, P = Sound Pressure, SPL = Sound Pressure Level.
