Testing was performed using an 18pf input adaptor under the following conditions: Reference level 114
dB @ 1 kHz, Reference Range 50 dB to 140 dB, Cal level 394.9 mV for testing level ranges – 20 dB to 70
dB through 50 dB to 140 dB. This represents a nominal sensitivity QE4936 microphone, 34.45 mV for
testing level ranges 60 dB to 150 dB and 70 dB 160 dB this represents a nominal sensitivity QE4110
microphone, 10.29 mV for testing level range 80 dB to 170 dB this represents a nominal sensitivity.
