dBA weighting filter frequency to dBA and dBC dB(A) and dB(C) A weighted sound calculate DIN IEC 651
Also no dBC measured values can be converted to dBA values. The frequency composition of the signal is not known. Readings of a pure 1 kHz tone should be identical, whether ... The A-weighting filter curve is defined from 20 Hz to 20 kHz. This is intended...
