(b) White noise is generated by a sound source. To study the acoustic behavior of the source, a microphone is used to measure such sound signals. If the sensitivity of this microphone is -47 dB (relative to 1000 mV/Pa). Determine the magnitude (in mV) of the microphone's electrical signal produced by a sound pressure level of 78.6 dB. (5 marks)
