Hospitalization in intensive care is a source of intense stress for both patients and their family. Post-intensive care syndrome (PICS) may affect both patients and their family. Outside the acute care in intensive care unit, non-drug therapies are gradually proving effective in reducing stress and pain. The investigators would like to know whether the beneficial effects of music therapy can be transferred to their intensive care patients. The aim of the project is to evaluate an innovative and personalized music diffusion system using a sound shower on the family anxiety in the intensive care waiting room. In this study, the investigators will compare the family anxiety in the intensive care waiting room, with or without music played through the sound shower.
