This sequence measures the frequency response of Bluetooth smart glasses microphones. After pairing the device with the BQC-4149 and mounting it on a HATS, a stimulus is played through the mouth simulator and recorded by the microphone. The HarmonicTrak algorithm then analyzes the recording to display the fundamental frequency response.
