Tinnitus is the perception of sounds in the ears or head that do not come from an outside source. It is a common condition, with similar prevalence rates in children young people and adults.

The NHS Joint Strategic Needs Assessment Guidance (2019) reports that:

  • 10% of the population will have tinnitus at some point
  • and it will be moderately annoying in 2.8% of the population; severely annoying in 1.6%; and disrupting a person's ability to live a normal life in 0.5%

Estimated that 3% of adults might require a clinical intervention for tinnitus. The expectation is that a similar number of children will need clinical intervention for tinnitus (1)

  • most cases are benign, but since there are serious and treatable causes, it should always be assessed thoroughly
    • generally, pulsatile tinnitus, unilateral tinnitus and tinnitus connected with other unilateral otologic symptoms are considered to be associated with more serious underlying disorder than bilateral tinnitus (3)

Tinnitus can be associated with difficulty in concentrating and listening, and for some people it can be extremely distressing and have a significant impact on their mental wellbeing, family, work and social life
