- DescriptionMEMS microphones from ST are omnidirectional which means that there is no sensitivity change to every different position of the source of the sound in space. The directionality can be indicated in a Cartesian axis as sensitivity drift vs. angle or in a polar diagram showing the sensitivity pattern response in space.MEMS microphones, also known as silicon microphones, are now commonly used in smartphones, tablets, laptops, hearing aids, voice biometric, digital voice assistants, and more.Dimensions: 3.1*2.5*1mm
