Capacitive microphone test solution
1. The test only takes 3s.
2. One-click automatic test on all parameters.
3. Automatic test report generation and storage.
4. Test results cover microphone parameters such as frequency response, distortion, sensitivity.
Test results - power curve
The output power curve is obtained by gradually changing the input sensitivity.
Test Results - Frequency Response Curve (1/6 Oct Smooth)
Abnormal peak factor: residual signal peak/residual signal finite value through high-pass filter
The limit is usually set to 12dB, or set according to product and environmental factors
