Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Sound works and binaural beat audio of a half hour duration will be assessed for their ability to affect anxiety in emergency department patients. Soundworks include musical and non-musical sound compositions. These may take the form of sounds derived from nature or urban environments and electro-acoustic instruments. Binaural beats or binaural tones are auditory processing artifacts, or apparent sounds. They are perceived in the brain independent of physical stimuli. Two sounds that are similar but slightly different in frequency will beat to produce two new frequencies, the sum and the difference of the original two sounds. These interventions will be applied to participants as electronic files audible through headphones. The interventions are given to participants after they have received medical assessment. This will occur at a point in time after initial assessment by the triage nurse (up to four hours in some cases). All patients will be located in a emergency cubicle.

Comparator / control treatment
1) CONTROL GROUP 1: Live ambient sound of the test environment of half an hour duration. Ambient sound will be audible without headphones.
2) CONTROL GROUP 2: Simulated ambient sound of the emergency department of half an hour duration and delivered through headphones. This will be delivered to participants after medical assessment is complete; this timepoint is identical to that for experimental interventions.

Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Patients will be consented by a clinician. Baseline measurements will then be recorded after which a sealed envelope containing the group to which the participant will be allocated will be opened. This allocation will be codified so that the researcher and participant are blinded to the group allocation until allocation is complete.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
computer generated block randomisation sequence
Masking / blinding
Open (masking not used)
