What is conversion between dB and sensor output voltage? How to calculate the amplitude in dB?
Brief:The amplitude of the AE signal is usually in unit of dB. The definition of 0dB is 1μV. The calculation of AE amplitude to dB value is:
The amplitude of the AE signal is usually in unit of dB. The definition of 0dB is 1μV. The calculation of AE amplitude to dB value is:
dBAE = 20lg(VAE/1μV)
