Posters urging passengers to use headphones are now being added to the Elizabeth line and will appear across other TfL services from the autumn.
It's taken a similar approach with its campaign against sexual harassment, with posters about behaviours like staring, touching and cat-calling being added to TfL's network in 2021.
Other transport operators are also thinking about how they tackle this kind of behaviour on their own networks.
C2C, which operates trains in the East of England, says it "welcome[s] discussions around improving passenger etiquette and reducing disruptive behaviour".
Meanwhile, Transport for Wales says it is "implementing new customer messaging to promote respectful and mindful behaviour".
Brighton & Hove Buses also says it's reviewing "how we encourage passengers to be more considerate to others when travelling on our buses".
Passengers told the BBC they welcome the decision to add posters about nuisance noise.
But some are sceptical that the posters and corresponding social media campaign will be enough to change people's behaviour.
Rachel agrees and says passengers often don't feel comfortable asking other people to turn their sound down. She thinks more staff are needed on public transport instead, to reprimand noisy passengers.
"I don't think the people that do this feel any guilt and responsibility," Rachel says.
