With smart speakers being a relatively new class of consumer audio device with unique characteristics, testing the overall end-to-end performance of a smart speaker’s primary input and output audio paths can be quite challenging.
Smart speakers are a relatively new class of consumer audio device with unique characteristics that make testing/measuring their audio performance difficult. In this 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 article describes the advantages of open-loop sensors over closed-loop current sensors. Examples of LEM and Honeywell open-loop sensors are described.
Chemiresistive sensors provide a low-cost means of measuring concentrations of a wide range of gases in applications such as industrial control, HVAC systems, and health and safety...
