Peltor™ Aviation Headset, 0.5 mV at 114 dB SPL (Microphone), 92 dBA at 0.5 VRMs/1 kHz (Earphone)

Peltor™ Aviation 8103 helicopter headset has an ambient noise cancelling differential microphone, specially designed for aviation intercom systems. The microphone amplifier is designed for intercom systems with 5 Ohm impedance. The frequency range is adjusted for good speech recognition. The earphones have a more limited frequency range, to give the best possible speech recognition in the ambient noise of a helicopter. Spiral polyurethane cable with molded NATO standard connector.
