[b] The IEC 60027-3 standard recommends the following format: [14] L x (re x ref) or as L x/x ref, where x is the quantity symbol and x ref is the value of the reference quantity, e.g., L E (re 1 μV/m) = 20 dB or L E/(1 μV/m) = 20 dB for the electric field strength E relative to 1 μV/m reference value. If the measurement result 20 dB is ...
