1. A microphone assembly comprising:

  • a housing having at least one acoustic port;

    a transducer disposed in said housing and acoustically coupled to said acoustic port;

    a windscreen sealed across said acoustic port, said windscreen having hydrophobic properties to prevent water from penetrating said housing through said acoustic port; and

    said windscreen having an acoustic resistivity of at least 1 acoustic Ω

    /cm2;

    a circuit board having a hole sized to receive at least a portion of said transducer, wherein said transducer is mounted within the hole in the circuit board such that a portion of said transducer extends below a bottom surface of said circuit board.
