'This is something we have been campaigning for, and we want other manufacturers to do the same,' she said. 'We will be working out how to use this success as part of DLTM, to show other companies why Apple's move is important in the context of preventing hearing loss.'
Last Thursday the charity applauded Apple in a statement that also warned of 'much more work to be done'. DLTM aims to inform manufacturers and music lovers of the potential dangers of listening to portable music players too loudly.
'RNID is delighted that Apple has responded to DLTM by allowing iPod users to reduce the volume limits, and we would urge other manufacturers of personal music players to follow suit,' the statement added.
The downloadable update works on late generation iPods and iPod Nanos, and includes a 'combination lock' that allows parents to set the volume threshold for their children's devices.
DLTM has been running since 2003 and is targeted at 18 to 30-year-olds. Last autumn Barclays gave in-store backing to the campaign by selling pin badges (PRWeek, 28 October 2005).
