COUNSEL FOR
Keep personal audio personal
Transport for NSW explicitly asks passengers to use headphones, keep the volume down and speak quietly on calls. The advice treats noise as a shared-space courtesy rather than a question of musical taste.
Headphones let one person enjoy media without asking a whole carriage, waiting room or café to participate. The expectation is easy to understand across languages and cultures.
A norm can remain proportionate: urgent calls, accessibility needs, emergencies and spaces deliberately designed for shared entertainment are obvious exceptions.
COUNSEL AGAINST
Not every sound is avoidable or inconsiderate
Some people use speaker audio because of hearing, dexterity or device limitations that are not visible. A rigid rule can turn ordinary accessibility needs into public confrontation.
Shared spaces already contain conversation, children, announcements and environmental noise. Singling out phone audio can reflect irritation or cultural preference more than measurable harm.
Headphones can also reduce awareness of safety announcements and surroundings. Courtesy should focus on volume, duration and context rather than requiring one device in every setting.
The judge’s direction
What the evidence can — and cannot — settle
The strongest global norm is modest: keep personal media and non-urgent calls quiet in enclosed shared spaces, usually by using headphones. Treat accessibility, safety and the purpose of the space as part of the evidence, not loopholes.
