SPL sound level to dB pressure level sound pressure

WebdB and dB (A) dB (abbreviation for decibel) is the "unit" for both pressure and power level. It's not a unit because it's the logarithm of a quotient, that's why Lp and LW are both expressed in dB, each with a different reference. The decibel is essentially unit-less! The A in dB (A) is not supported by ISO standards. WebSound pressure level (SPL) is the pressure level of a sound, measured in decibels (dB). It is the ratio of the Route Mean Square (RMS) of sound pressure to the reference of sound pressure (the reference sound pressure in air is 2 x 10-5 N/m2, or 0,00002 Pa).
