Free Download Package – Application Note: Smart Speaker Acoustic Measurements & TechNote 140: Testing Microphone Arrays with PDM 16 Module


Smart speakers are a relatively new class of consumer audio device with unique characteristics that make testing their audio performance difficult.

In the 17-page application note, we provide an overview of smart speaker acoustic measurements with a focus on frequency response – the most important objective measurement of a device’s audio quality.

This Audio Precision technote discusses MEMS microphone and mic array measurements, including important considerations and a detailed example test procedure.
