Snoring can be accompanied by obstructive sleep apnea (OSA), which in turn may be associated with many pathological conditions including hypertension and congestive heart failure. Although OSA can be treated with positive airway pressure devices, they can have a low degree of compliance with patients. A simple monitor which quantifies the amount and type of snoring each night could help individuals control their degree of snoring by providing daily feedback (in addition to the kick-o-meter provided by
one's partner). The proposal is to use multiple microphones and independent component analysis (in cocktail party problem mode) to distinguish snores on one side of the bed from environmental noise.
