Dynamic Snore Microphones offer a wide frequency range, and sensitivity to other respiratory sounds besides snoring. The sensor converts snoring, and other sounds in the audio range picked up through the skin, to a small analog voltage that provides a clear, reliable indication of the presence of these sounds. The sensor may be connected to any AC (low level) channel on the recorder.
