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 20±2°C, humidity at 65±5%, unless otherwise noted.
