Ising dB addition, calculate the overall sound pressure level due to the machine in both dB and B(A). b) With one violin playing the sound pressure level at a certain place is measured at 50dB. If six violins play equally loudly, what will the sound pressure level most likely be at this same place? c) Explain what is meant by the term A-weighting d) Explain what is meant by the following microphone properties
