Mosomic MEMS Microphone Guide


The Mosomic MEMS microphone Guide is a comprehensive guide on MEMS microphones. The goal is to help device manufacturers design and develop high quality MEMS microphone solutions into their smartphones, smart speakers, IoT applications, appliances, and so on. The guide addresses most things one needs to know about the characteristics and use of MEMS microphones. 


The guide consists of 25 episodes with an average duration between 15 and 20 minutes. The total duration of the guide is more than 7 hours.


The target audience for this guide is everyone who wants to learn about MEMS microphones: People who use microphones in their devices, microphone purchasing people, engineers who implement microphones into devices, microphone manufacturers, microphone marketing people, CE executives who need to understand what microphones are and what they can do and, of course, students studying acoustics, audio or electrical engineering.
