According to the survey by Royal National Institute for Deaf People (RNID), nearly half of those polled admitted that they had suffered pain in their ears from loud music.
More than 80 per cent agreed on feeling a ring in the ears or dullness of hearing after listening to loud music.
The charity questioned 2,700 people at music festivals across the country.
"These results issue a stark warning about the UK's future hearing health," the Telegraph quoted Emma Harrison, from the RNID, as saying.
"Volume levels at festivals can reach levels over 110 decibels - that's the same as a jet plane taking off.
"Repeated listening at this volume will cause premature hearing loss," she added.
Sound levels of more than 85 decibels are likely to damage hearing over time.
The charity suggests that the festival-goers take regular breaks from the loudest areas to protect their hearing.
