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.
Claims20
A system for globally suppressing snoring signals generated from a snore sound source wherein a snoring sound signal has a phase angle and amplitude associated therewith, the system comprising:
- means, proximate the snore sound source, for receiving the snoring sound signal;
- sound transducing means proximate the snore sound source for directing a snore cancelling signal toward the snoring sound source to form a doublet between said sound transducing means and the snore sound source;
- and
- means, operatively coupled to said receiving means and to said sound transducing means, for generating said snore cancelling signal based on said received snore signal, such that said snore cancelling signal, as measured at a plane of emission of said sound transducing means, has approximately an 180 degree phase difference from the snoring signal phase angle and a substantially same amplitude as the snoring signal amplitude as measured at the sound source.
A system for globally suppressing snoring signals generated from a snore sound source wherein a snoring sound signal has a phase angle and amplitude associated therewith, the system comprising:
- means, proximate the snore sound source, for receiving the snoring sound signal;
- sound transducing means proximate the snore sound source for directing a snore cancelling signal toward the snoring sound source to form a doublet between said sound transducing means and the snore sound source;

- means, operatively coupled to said sound transducing means, for determining a position of said snore sound source;
- and
- transducer control means, operatively coupled to said sound transducing means and to said receiving means for preventing said cancelling signal from being output by said transducing means when the snoring signal, as received by said receiving means, is not within predetermined signal criteria.

- determining a position of said snore sound source during movement of said snore sound source;
- and
- preventing said canceling signal from being output by said transducing means when the snoring signal, as received by said receiving means, is not within predetermined signal criteria.
