Hearing loss symptoms: A ringing sound may be indicative of the condition

The cochlea is lined with numerous sound-sensing hair cells that turn sound waves into electrical signals.

The hearing nerve sends these electrical signals to the brain, which interprets them and recognises them as sound.

When a person has hearing damage, the number of electrical signals sent to the brain decreases.

Research has shown that the brain then tries to “fill in the gaps”, which is a major cause of tinnitus.
