WebThis converter allows converting the sound pressure in pressure units into the sound pressure level in logarithmic units, which measure the effective pressure of a sound relative to the reference value of 20 μPa. Webµ o = 4 p x 10 -7 H/m. Converting from T to pT and from A/m to µA/m, and deriving the Log, the constant becomes: 240 - 120 + 20Log 10 [4 p x 10 -7] = 2.0. dBpT = dBuV + dBpT/uV + Cable Loss. dBuV/m = dBpT + 49.5 dB.
