Exploring the Link Between Hearing Loss and Tinnitus

Exploring the Link Between Hearing Loss and Tinnitus

Tinnitus is the perception of sounds that have no external source. Some causes of tinnitus are well-known – loud noises, ear infections etc – but in some cases the cause remains mysterious. In addition, while not everyone who experiences hearing loss will experience tinnitus, there does appear to be a strong connection between hearing loss and tinnitus.

The Link Between Hearing Loss and Tinnitus

It is estimated that as many as 90% of people who experience tinnitus also suffer from some degree of hearing loss. Researchers believe this indicates that damage to the auditory system may cause tinnitus. There are different kinds of damage that may cause this.

Damage to the Cochlea

The cochlea is the inner ear’s primary vehicle for detecting and interpreting sound vibrations. Damage to the cochlea can cause hearing loss and disrupt its ability to process sound vibrations properly, leading to a disruption in the way auditory signals are transmitted to the brain.

The brain may attempt to fill in or smooth out gaps or rough patches in the sound transmission creating what we experience as tinnitus. Some researchers theorize that tinnitus may be a side effect of the brain attempting to adapt to changes in auditory signals it receives as a result of hearing loss. 

Long-term exposure to loud noise, proximity to sudden traumatic sounds (explosions etc) and some medical conditions can cause damage to the cochlea and hearing loss

Damage to the Auditory Nerve

Damage and poorly developed Auditory Nerve due to trauma or other medical conditions may also lead to tinnitus in one or both ears. Hence tinnitus can be a first sign of something more sinister and it is worth assessing the auditory nerve and the function of the cochlea alongside standard hearing tests.
