Knowles Booms

Booms groupKnowles' 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.

Collaboration with commercial, governmental and industrial designers is producing new helmet applications for aircraft, military, first responder and high-noise manufacturing environments.

Headset booms allow the microphone to be placed in the near field, where a noise canceling microphone responds the difference in acoustic pressure. The combination of a good close-talking microphone element and close proximity to the mouth provides excellent signal to noise even in extremely noisy conditions.

Those boom microphone assemblies are mainly used in :

    • Lightweight noise-canceling headset for telephony, computer speech recognition, or other indoor use (Security, Police, Fire, Dispatcher etc.)
    • Helmet or face mask integration
    • Radio communication (Aviation, Industrial, In-ear, Professional, Military)
    • And Sensor (Shot detection, Unattended Ground Sensors)

Several series of boom & sensor microphones are available : W, U, I, O, M, R, F and H.

W, U, I, O, M and R series are boom microphone assembly:

    • W series – smaller footprint, lighter weight offering noise cancellation and IP67 rating
    • I series – noise cancelling with self-powered microphone element
    • M series – noise cancelling, waterproofing to IP68 rating
    • R series – designed for aviation customers looking for TSO/RTCA compatible noise cancelling electret microphone


W, O, M and R series are mainly built-in with EK, NR and WP specialty transducer microphones.
U series are built-in with FG and DFG specialty transducer microphones.
I series are built-in with BJ specialty transducer microphones.

F and H series are sensor microphone assembly:

    • F series – Panel mount design for outdoor applications
    • H series – Designed for use in outdoor sensor arrays for fixed or mobile installations. Detects time of arrival and acoustic signature for source triangulation and identification


Both F and H series are built-in with highly sensitive EK or WP specialty transducer microphones.
