Important Information:

"Pascal (Pa)" is being used as the indication of sensitivity, as per the recommendation by the International Electrotechnical Commission  (I.T.C.) .  The sensitivity that indicates in "Pa" will increase 20dB compared with the "µ bar".
 For examples: -60dB (0dB = 1V/µ bar) = -40dB (1V/pa)
