The study, by charity Deafness Research UK, claims there is a disturbing lack of knowledge of treatments available for the distressing condition.

More than half a million Scots are affected by noises in the head or ear which can vary from a low hum to noise levels equivalent to a jet engine.

They often cause anxiety, lack of sleep and depression.

The research shows three quarters of people in Scotland who sought help from the NHS for their tinnitus had not received any of the generally accepted treatments.

More than 40% were not even referred to a consultant by their GP.

Those GPs who were unwilling to refer their patients to a specialist also tended to be unsympathetic about symptoms.

Although guidelines issued to GPs say making negative remarks about tinnitus can worsen patients' symptoms, the research found three quarters of these people were told, "there is no cure, you'll have to live with it".

The findings were announced at a launch of the charity's campaign to educate tinnitus sufferers and health professionals about treatments.

Actor William Roache, who plays Ken Barlow in Coronation Street, has the condition, said "I find it appalling tinnitus sufferers are being so badly let down by NHS."
