Bed system for detecting snore side
This document generally describes bed systems for automatically determining which side of a bed a detected snore originates from, where two sleepers are in the bed. A bed system can include sensors for collecting acoustic readings and pressure readings, on respective sides of the bed. The collected sensor readings can be processed by a computer system to determine whether a snore is detected at the bed system and which side of the bed system the snore originates from. Based on the determination of the snorer side of the bed system, the computer system can also generate one or more actions, which can be used to mitigate, reduce, or otherwise stop the snoring on the determined snorer side of the bed system.
