The move is part of the charity's new corporate strategy, launched earlier this year, that aims to strengthen its work researching and campaigning on how hearing loss and damage can be prevented.
Both the executive director of fundraising John Trampleasure and the executive director of advocacy and policy Brian Lamb will leave their roles, while the charity recruits an MD of external engagement to oversee all its external comms work. All the changes are expected to take place by April 2010.
Lamb is moving to a new position within the organisation, to set up a cross-sector coalition to promote the value of hearing. He will be working with other voluntary organisations, central government bodies and private sector firms such as hearing aid manufacturers. He will also continue to run The Lamb Inquiry, which is backed by Schools Secretary Ed Balls, and researches the state of special education needs in the UK.
Meanwhile Trampleasure will join the World Society for the Protection of Animals as international director of fundraising, marketing and comms. He will be responsible for creating effective messaging across the globe and helping to support the organisation's 15 global offices.
Trampleasure replaces Amanda Seller, who joined the Office of the UN High Commissioner for Refugees in April.
