Music to Decrease Pain and Anxiety During Head CTs Performed at the PEds ED

Inclusion Criteria: * We sampled all children up to ages 3 years who present to the PED during the hours that the research assistant was present to collect data. Exclusion Criteria: * All children requiring trauma room care were excluded because they were not able to move to the study's examination room after triage (their care will be completed in the trauma room). Children with hearing deficit and those who are unable to move to the designated examination room for other reasons including needing oxygen and cardiopulmonary monitoring were excluded as well. The patients were also excluded if we were unable to track their results or chart at final review of patient data.
