Abstract
A system delivers auditory sleep stimulation. It is able to generate masking sounds for masking external noise as well as sleep stimulation tones for promoting deep sleep. Noise masking sounds are provided in a frequency range including first and second frequency bands, before the onset of sleep. In response to the detection of particular sleep characteristics (such as a particular sleep stage), the noise masking sounds in the second frequency band are stopped. Instead, sleep stimulation tones are provided in the second frequency band. Thus, noise masking continues but the sleep stimulation tones are not masked.
Claims15
A system for delivering auditory sleep stimulation, comprising:
- a sound generator system for generating noise masking sounds for masking external noise and for generating sleep stimulation tones for promoting deep sleep;
- a sleep monitor;
- and
- a controller, wherein the controller is adapted to:
- use the sound generator system to provide noise masking sounds in a frequency range including first and second frequency bands, before the onset of sleep;
- use the sleep monitor to detect particular sleep characteristics;
- in response to the detection of the particular sleep characteristics, stop providing the noise masking sounds in the second frequency band;
- and
- provide sleep stimulation tones in the second frequency band.
A method for delivering auditory sleep stimulation, comprising:
- generating noise masking sounds for masking external noise in a frequency range including first and second frequency bands before the onset of sleep;
- monitoring sleep, and in response to detection of particular sleep characteristics, stopping the provision of the noise masking sounds in the second frequency band;
- and
- providing sleep stimulation tones for promoting deep sleep in the second frequency band.
