WebThe classic relationship between a single-point source sound power level and room sound pressure level at some frequency is. Equation 1. Lp = Lw + 10 log (Q/4πr2 + 4/R) + 10.3. Where: Lp = sound pressure level, dB re 20 µPa. Lw = sound power level, dB re 10 -12 W. Q = directivity of sound source (dimensionless) WebConvert dB, dBm, dBW, dBV, dBmV, dBμV, dBu, dBμA, dBHz, dBSPL, dBA to watts, volts, ampers, hertz, sound pressure.
