The National Deaf Children's Society has released research today which shows that more than three quarters of young people have no idea how to communicate with someone with hearing loss.
The survey of 1,000 UK teenagers also found that more than a quarter would probably not make the effort to talk to a deaf person of the same age, even though two thirds of teenagers said that making new friends is important to them.
Scott from Telford is partially deaf.
He's 16, and goes to mainstream school with hearing children.
He wears hearing aids which mean that although loud noises can be a problem, he can hear reasonably well.
Despite this, his deafness has caused some difficulties with other pupils in the past.
