The RNID has launched an awareness-raising campaign that will use microphones to pick up sound in an area and display the levels on an advertising screen.
The adverts will carry slogans that will be updated regularly and will highlight the fact that hearing loss affects one in seven people in the UK.
The slogans include: "One in seven people would be happy to hear a dentist's drill"; "One in seven would love to hear that their partner's ex was a better lover"; and "One in seven would love to hear about the VAT increase".
The charity has not yet been able to secure any free media space in which to show the campaign.
The campaign, developed by advertising agency M&C Saatchi, has been set up to remind people how important their hearing is and to encourage them to have hearing checks and not to play loud music on MP3 players.
Jackie Ballard, chief executive of the RNID, said: "We are really excited about the campaign, which will help to communicate our message in a very visual and emotive way."
