In my application (a microphone coupled to a reflector dish to focus the sound) I would like to minimize the sound from the sides (off-axis) of the dish. The Invensys MEMS microphones are omnidirectional?
Another microphone company vents both sides of the microphone diaphragm in their noise reducing designs so that the ambient noise works on both sides of the diaphragm. The louder direct path sound is concentrated more on one side. These microphones are directionally sensitive. Is there a similar Invensense product?
