Ktell was designed for use in psychiatric "intensive care rooms" (ICRs) as part of a research project conducted by the amenhotep group.

By providing this music interface, patients are helped through episodes of psychological crisis in a challenging environment, and care-givers are supported in their professional practice. In so doing, amenhotep has developed a way to empower patients through control over their sound environment.

Preserving autonomy

When patients are placed in ICRs, they can take charge of their music listening and have some control over their environment. The use of the music listening device has a real impact on the experience of patients in ICRs.

Four emotional dimensions

Joyful activation

Joyful, lively, catchy, dancey, sometimes cheeky, playful and sparkling music.


Memory-evoking, melancholic, sentimental, dreamy music.


Relaxed, serene, peaceful, meditative, contemplative music.


Restless, jumpy, awe-inspiring, worrying, dark music.

The music selection has been thought out to provide four emotional themes, and patients can freely choose from among them according to their current state of mind. Their lyric-free nature allows for a more open and intimate interpretation of the sounds. To cater to the broad range of patients, there are a variety of styles, including classical, jazz, folk and film music.


The device opens up the possibility of engaging in a dialogue around music. Its use has a real impact on the experience of patients in ICRs.


The music player complies with the strict safety regulations of acute psychiatric wards. Care-givers can also adjust the volume and deactivate the device if necessary.


The unit is ergonomic and aesthetic and sits flush in the wall of the room.
