Low Flow-Noise Microphone for Active Noise Control Applications

A method that couples output from a hot-wire anemometer with that of a microphone to reduce flow-induced pseudonoise from the microphone signal was developed. In these experiments, a microphone and a hot-wire sensor were placed in a well-defined low-speed turbulent flow in a rectangular duct. Contro...
