1. A vehicle microphone assembly comprising:

  • at least one directional transducer having a first side and a second side and a plurality of transducer acoustical ports located on the first side of the at least one directional transducer;

    a circuit board having a first side and a second side and a hole in said circuit board sized to receive at least a portion of said at least one directional transducer such that the plurality of transducer acoustical ports are located on said first side of said circuit board;

    an acoustic seal formed between the at least one transducer and the first side of the circuit board for preventing acoustic energy from entering said plurality of transducer acoustical ports of said at least one directional transducer from said second side of the circuit board; and

    wherein said at least one directional transducer is mounted within the hole in the circuit board such that the acoustic seal extends substantially around said second side of said at least one transducer, preventing acoustical energy from entering the transducer acoustical ports from the second side of the circuit board.
