The difference between the concept of unit "Pascal" and the one of unit "ubar" can be explained as follows.In calibrating the sensitivity of ECMs, the sensitivity is manifested differently according as the unit is "Pascal" or "ubar".That is, the sensitivity will be increased by 20dB in the usage of unit "Pascal".Example:－62dB(0dB=1v/ubar)=－42dB(0dB=1v/pascal)
