  • Snoring suppression system
    Patent number: 5444786
    Abstract: An adaptive snoring signal suppression system globally cancels snoring signals by determining a canceling signal based on a received snoring signal. The system creates a doublet between a plane of a speaker and the source of the snoring signal such that at the plane of the speaker, the canceling signal is 180 degrees out of phase with the snoring signal as measured at the source. The system uses digital signal processing to adaptively estimate a snoring sound canceling signal based on past snoring signals.
