Comparador activo: Application of tones
During non-rapid eye movement (NREM) sleep short tones will be played
|
During NREM sleep, tones (max.
60 dB) will be played using a portable, safe, in-home device.
This device records biosignals (e.g.
brain activity) and precisely times the tones during NREM sleep.
It was developed and produced by the ETH Zurich and approved for use in this study by Swissmedic
|
|
Comparador falso: No application of tones
During NREM sleep no short tones will be played
|
This is the sham-control intervention; The device will only record biosignals but will not play tones.

|
Sleep quality
Periodo de tiempo: From baseline period to study completion, assessed up to 2 months
|
Objective information about sleep macro- and microstructure will be assessed including measures like sleep architecture, amount of slow wave activity (SWA), amount of spindles, awakenings during sleep, and sleep fragmentation.
In addition, subjective sleep quality will be obtained by questionnaires every morning over the intervention period.
These measures will show whether auditory stimulation enhanced overall sleep quality compared to sham.
