The Effect of Music and Environmental Noise Isolation on Bronchiolitis Severity in Hospitalized Children: a Randomized Control Trial


Bronchiolitis is an infectious disease, with no effective treatment. Music and Mozart's works specifically, has been shown to have a positive effect on physiological parameters, while environmental noise is considered to be harmful. We aimed to evaluate the short-time effect of listening to music and detachment from environmental noise on the severity of bronchiolitis in hospitalized children.

  • Study Type: Interventional
  • Study Design
    • Allocation: Randomized
    • Intervention Model: Parallel Assignment
    • Primary Purpose: Treatment
    • Masking: Triple (Participant, Care Provider, Investigator)
  • Study Primary Completion Date: February 28, 2019

Detailed Description

MP3 player devices were uploaded with 3 different pieces: 1) sonata for 2 pianos in D major, K.488 by Mozart (2) instrumental music ("To the Point", by Dean Evenson & Tom Barabas) and (3) silence. All music or silence pieces were identical in length (24 minutes in accordance to the duration of the sonata). Music fragments were played using headphones suitable and approved for use in children – GSI (Grason-Standler) Insert Earphone TIP-50 (50 ohm) (Grason Standler Inc. Madison, WI, USA). Sound frequency and volume were adjusted to the age appropriate values33 Children were randomly divided into 3 groups according to the type of intervention. Randomization, numbering of the MP3 players and coding of the content were done by a research coordinator not involved in evaluation of the patients nor in analysis of the results.


  • Behavioral: Mozart
    • Music composed by Mozart, a musical piece 24 minutes long.
  • Behavioral: Instrumental music
    • Instrumental music , a musical piece 24 minutes long
  • Behavioral: Silence
    • Silence, a piece 24 minutes long.

Arms, Groups and Cohorts

  • Active Comparator: Sonata for 2 pianos in D major, K.488 by Mozart
    • An Mp3 player, upload with music by Mozart. Music was played using headphones suitable and approved for use in children.
  • Active Comparator: Instrumental music (“To the Point”, by Dean Evenson & Tom Barabas)
    • An Mp3 player, upload with instrumental music. Music was played using headphones suitable and approved for use in children.
  • Active Comparator: Silence
    • An Mp3 player, upload with silence. Silence was played using headphones suitable and approved for use in children.

Clinical Trial Outcome Measures

Primary Measures

  • Change in disease severity
    • Time Frame: Evaluation was done before music playing and immediately after the end of the music session (At 0 minutes time, and at a maximum time of 24 minutes from the beginning of intervention – which is the length of the musical piece).
    • Evaluated by Modified Tal Score (Respiratory rate, O2 saturation, use of accessory respiratory muscles, breath sounds: wheezing)
