The goal of this study is to evaluate whether classical music in the Emergency waiting room can diminish perception of waiting times. Patients and relatives, after arriving in the ER waiting room will either listen to live classical music, recorded classical music, or no music at all.

The study was submitted to the ethics committee as an interventional clinical trial; however, they advised that it does not qualify as a clinical trial. The project does not collect health-related information from patients, according to the definition provided by swiss research law, and therefore does not require any authorization. They qualify it as a quality control initiative.

Please advise on how we should register it into clinicaltrials.gov, we might need the ID for publication purpose.

Thank you
