It is estimated up to 20% of people in Northern Ireland suffer from tinnitus - ringing or buzzing in the head or ears.
A recent survey revealed almost 9,000 people found the condition made their life unbearable and had a significant impact on their mental health.
RNID, the charity which represents deaf people, said it is a hidden, distressing condition.
While there is no cure, they want sufferers to have access to more professional help and support.
The charity's Claire Lavery said: "There's a range of therapies that can provide help for people - psychological approaches to tinnitus, cognative behavioural therapy for example.
"People can learn relaxation techniques, they can learn a lot from information about what it is causes tinnitus and how the ear works for example and they can buy products that can mask the sound."
