BOOM MICROPHONES & SENSORS

Knowles’ boom microphones are designed for either flexible or rigid configurations and offer such performance options as noise rejection and high-frequency crossover of near and far field responses. Lengths and end terminations are customized to meet your application needs. Marketers of headsets and audio systems often seek Knowles boom designs. Collaboration with commercial, governmental and industrial designers is producing new helmet applications for aircraft, military, first responder and high-noise manufacturing environments.
