Aim: Bronchiolitis is an infectious disease, with no effective treatment. Music and Mozart's works specifically are known to have a positive effect on physiological parameters, while noise is considered harmful. We aim to evaluate the short-term effect of environmental noise detachment and/or music listening on the course of bronchiolitis in hospitalised children. Methods: This is a prospective, double-blinded randomised controlled trial. Patients were divided into three intervention groups: 1-Mozart's Sonata, 2-instrumental music, 3-silence. Music was heard via media players and soundproof headphones. Disease severity was evaluated before and after intervention using the Modified Tal score. Results: Seventy music sessions were included in the analysis (Mozart n = 23, instrumental n = 22, silence n = 25). A one-point drop in the average bronchiolitis severity score was observed in all three groups from 7.1 (CI 95%, 5 to 9.2) to 6.1 (CI 95%, 4.3 to 7.9), p < 0.001. No significant difference was found between the three groups with respect to change in the severity score before and after the intervention. Conclusion: Isolation from disturbing sounds heard in paediatric departments could be considered a simple non-invasive intervention in children hospitalised with bronchiolitis. Further studies are warranted to evaluate long-term effects of this intervention and the specific effect of music.
