1. 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 a stored history of environmental noises over the period of time;
determining a timing of when a reoccurring potentially disturbing noise will occur by determining patterns, onsets and offsets, intervals, and frequencies of the environmental noises;
obtaining a current measurement of the at least one biosignal parameter of the subject;
predicting whether the potentially disturbing noise will disturb the subject based on the analyzing of the stored histories, the determined timing of the potentially disturbing noise, and the current measurement of the at least one biosignal parameter;
outputting a masking sound to maintain a current sleep condition based on the analyzing of the stored histories prior to an occurrence of the potentially disturbing noise when the potentially disturbing noise is predicted to disturb the subject.
