The campaign is due to launch later this year with an initial adspend of £1m. MPG will buy TV and print media for the campaign, aimed at encouraging people to recognise and address issues of hearing loss.
Sue Osborne, RNID campaigns co-director, said: "This is a crucial campaign for RNID, and we are convinced that MPG will make an excellent partner agency with the senior talent to bring our message to life."
She added that the challenge was to drive awareness of the issues and provoke action in those people who may benefit from modern hearing aid technology.
Mark Craze, MPG managing partner, said: "This is an exciting campaign with a really important message."
Last month, RNID hired Euro RSCG London to handle the creative for the account following a three-way pitch against Ogilvy & Mather and JWT. Media spend on the account could be up to £4m.
RNID is the largest hearing charity in the UK, representing 9m deaf and hard-of-hearing people.
