Using PXI to Build a High-Performance MEMS Microphone Testing System (533.21KB)

The demand for increasing microphone signal quality from handheld mobile devices has led to the development of microphone signal processing technologies such as: HD audio, noise cancellation, active noise cancellation, beam forming, directional reception, stereo sound field reconstruction, and speech recognition. As well, devices incorporating multiple microphones are becoming more and more popular. Several newly released smart phones now integrate multiple MEMS (Micro Electrical-Mechanical System) microphones for improved background noise cancellation. All flagship smart phone models in introduced in 2015 featured three or more MEMS microphones to support HD audio, ambient noise cancellation, noise filtering, directional reception and speech recognition. Popularity of MEMS microphones is expected to grow.
