    Electro-Voice incorporates.

    From Kahn in 1953: "The first block in this new business was the poor quality and high prices of available microphones. Sensing an opportunity, we purchased a lathe and drill press and began making them at the rate

  • The Hum-Bucking Coil

    Invents the first hum-bucking coil, a small coil adjacent to the voice coil of a dynamic microphone that cancels the 60-Hz hum produced by ac magnetic fields in the presence of the microphone. Hum-bucking coils are still used in microphones for noise-critical applications.

  • 1 Million Microphones

    Noise-canceling microphone production required by the military dramatically increases production at EV. Total production reaches close to 1 million microphones annually.

  • Award for the T-45 Noise-canceling Lip Microphone
