US 2021/0241745 A1 · DYNAMIC SOUND MASKING BASED ON MONITORING BIOSIGNALS AND ENVIRONMENTAL NOISES

Abstract

Aspects of the present disclosure provide methods, apparatuses, and systems for closed-loop sleep protection and/or sleep regulation. According to an aspect, sleep disturbing noises are predicted and a biosignal parameter is measured to dynamically mask predicted disturbing environmental noises in the sleeping environment with active attenuation. Environmental noises in a sleeping environment of a subject are detected, input, or predicted based on historical data of the sleeping environment collected over a period of time. The biosignal parameter is used to determine sleep physiology of a subject. Based on the environmental noises in the sleeping environment and the determined sleep physiology, the noises are predicted to be disturbing or non-disturbing noises. For predicted disturbing noises, one or more actions are taken to regulate sleep and avoid sleep disruption by using sound masking prior to or concurrently with the occurrence of the predicted disturbing noises.

Dependent claims

A method for regulating a sleep pattern of a subject, comprising:

analyzing a stored history of at least one biosignal parameter of the subject over a period of time and environmental noises over the period of time;
determining timings of sleep disruptions of the subject based, at least in part, on the stored history of the at least one biosignal parameter of the subject over the period of time and the environmental noises over a period of time;
obtaining a current measurement of the at least one biosignal parameter of the subject;
predicting, using the determined timings of sleep disruptions of the subject and the current measurement of the least one biosignal parameter, whether a potentially disturbing noise will disturb the subject based on a similarity between the potentially disturbing noise and the environmental noises;
and
outputting a masking sound to maintain a current sleep condition based on the analyzing of the stored history prior to an occurrence of the predicted disturbing noise.
