/m)-120]/20}. As above, simply plug away. dBW/m2 = 10Log10[V/m - A/m]. A simple relation to calculate decibel-Watts per square meter. dBmW/m2 = dBW/m2 + 30. The derivation for the constant in the above equation comes from the decibel equivalent of the factor of 1000 used to convert W to mW and vice... friction against the commutator, as well as arcing caused by current conducting through the brush and commutator. A reduction in noise level of 10 decibels is an impressive achievement. The decibel scale is logarithmic, not linear. Every three dB decrease of the sound level cuts the intensity...
