This sequence measures the frequency response, THD, and L/R balance of Bluetooth smart glasses speakers. After pairing the device with the BQC-4149 and placing it on a HATS, a 1 kHz pilot tone with a 20 kHz–100 Hz Stweep stimulus is played and captured through the ear simulators. The HarmonicTrak algorithm then analyzes the recording to display output performance.
