Note 1: For BSWA 200 instrument, ignore the result above 12.5 kHz due to the
microphone frequency response for Class 2 instruments.
Note 2: Data was measured with a microphone with a sensitivity of 50 mV/Pa for SW
1000 and 40 mV/Pa for BSWA 200.
Note 3: Measurement according to the requirements of GB/T3785 and IEC61672.
1.6 Information for regular tests

⚫ Reference direction of incidence : parallel to the direction of incidence of the
microphone.
⚫ Reference point of the microphone Center of the microphone diaphragm.
