A digital microphone noise reduction module that employs advanced algorithms to provide natural sounding clear speech communications in high noise environments. The aggressive Voice Operated Switch (VOX) mode always captures the first syllable and allows true hands free operation. This product combines state of the art Digital Signal Processing and carefully designed circuitry to ensure very low power consumption, and is easily installed between the headset microphone and radio or intercom device. Optimized for use with a headset microphone. For best performance in very high noise, a true noise-canceling microphone is recommended. Noise reduction is also effective for far-field microphones. Patents Pending.
