SNCF confirmed the fine was valid and in accordance with noise regulations despite the lack of a national law banning loudspeaker calls. Security personnel at SNCF are empowered to issue such fines to maintain peace at public transport facilities. Public opinion on using loudspeakers in shared environments remains overwhelmingly negative, prompting different approaches worldwide to enforce noise regulations. Countries like the UK and Japan have specific policies or cultural norms aimed at reducing disturbances from mobile phone usage, indicating a global dialogue over public conduct amidst evolving communication technology.
