The Dreem headband transmits three types of sounds by bone conduction:
- Sleep techniques to help you fall asleep that are audible;
- Stimulations (pink noises) that are not audible as you are in deep sleep stage;
- The alarm (Smart or classic).
If you have hearing-impairment, you will not perceive correctly the sounds emitted by the headband, thus depriving you of these 3 functionalities. Analysis and personalized coaching will work normally.
Note, however, that in case of transmission deafness, for which hearing is retained by bone conduction, Dreem sound features will be readily available.
