From wearables to home assistants, more and more devices are being asked to "hear" their environment. With the ability to capture almost any sound, MEMS microphones make it possible for a range of applications to achieve this. However, selecting and designing in the optimal microphone solution for your voice capture and audio recording needs can be challenging. To help make this process easier, we've combined three of our top MEMS microphone resources to ensure you make the sound decision for your design.
In this guide, CUI Devices engineer Bruce Rose reviews the two most common technologies used for constructing microphones, covering MEMS and electret condenser microphone basics, the differences between the technologies, and the advantages of each solution.
The MEMS microphone output you select has important implications on your design. This CUI Devices guide looks at analog and digital (PDM) interfaces of MEMS microphones and describes the advantages, tradeoffs, and design considerations of each.
The omnidirectional nature of MEMS microphones makes it possible for them to be configured in an array to reduce unwanted noise or form a directional response. In this guide, CUI Devices discusses MEMS microphones in phased array applications, design considerations, and the advantages/disadvantages of different array configurations.
