The use of live music in SICU might affect the perception of noise, which may reduce staff's stress level and further decrease the possibility of clinical errors, reduce patient's anxiety and perception of pain as well as increase compliance from patient and family. Live music might also enhance the quality of stay and promote a holistic healing process for the patient.

In this study, the research team is looking at the effect of the live music provided by a trained music therapist, created through incorporating the noises in the SICU - such as the beeping of the machines as part of the elements in the music, to organize the sound environment as well as introducing familiar songs, chosen according to the cultures and ages of the patients, caregivers and staff, to increase a sense of familiarity and comfort. Through the intervention, the research team hope to ameliorate the effects of a noxious sound environment, which may reduce the stress level of the staff and increase their acuity level while decrease patients and caregivers' anxiety level and improve their mood state and the quality of hospitalization
