Note 1: Ignore the result outside 20Hz~12.5kHz for type BSWA 309 alone due to microphone
frequency response of Class 2.
Note 2: The data was measured with 40mV/Pa microphone for BSWA 308 and BSWA 309.
Note 3: Measurement according to GB/T 3785 and IEC 61672.
Note 4: Measurement according to GB/T 3241 and IEC 61260.
1.6 Information for Periodic Tests
 Reference sound level: 94.0dB.
 Reference incidence direction: parallel to the incident direction of the microphone.
 Reference point of microphone: the central point of microphone diaphragm.
 Reference incidence direction: direction perpendicular to the microphone diaphragm.
 Reference attenuation of octave spectra: 0dB.
 Reference input signal level of octave spectra: 40mV (94dB for sensitivity of 40mV/Pa).
