sound, the reference unit is taken as 1 μPa, whereas airborne sound is usually referenced to a pressure of 20 μPa. To convert from a sound pressure level referenced to 20 μPa to one referenced to 1 μPa, a factor of 20 log (20/1) 26 dB has to be added to the former quantity. Thus a sound pressure of 60 dB re 20 Pa is the same as 86 dB
