The tube is ~80db (depending on line) so you're not going to hear it anyway.

but, if I was mayor, I would be getting the transport police to have a word with phones on speakers.

Sorry I don't mean you're lying.

I mean it depends on the line. Old northernline == 80db.

Elizabeth line, much quieter, so you're gonna hear it more
