Ringing in the Ears
Sound waves cause vibration or pressure on small structures in the ear. This creates signals that are sent to the brain. Damage to this system may cause signals to go to the brain when sound is not present. It may be caused by one or more of the following:
- Damage to inner ear hair cells
- Damage to the inner ear from being around loud sounds—this may last only a few minutes
- Ear bone changes such as stiffening of bones in the middle ear
- Ear wax build-up
- Age-related hearing loss
- Damage to ear drum or nerves
Pulsatile tinnitus is caused by the flow of blood. It happens with each heartbeat.
Different health problems can cause tinnitus or make it or worse. An exact cause may not be found.
Things that may increase your chances of tinnitus are:
- Work or activity that has loud noises
- Wax or an object in the ear canal
