We use the Pascal (Pa) indication of sensitivity as per the recomendation of I.E.C. (International Electrotechnical Commission). The sensitivity of Pa will increase 20 dB compared to the ubar indication. Example: -60 dB (0 dB = 1 V/ubar) = -40 dB ( 1V/Pa) 2. All specifications measured at 5~35C, humidity at 45~85%, under 86~106 kPa pressure, unless otherwise noted.
