Is it possible to reverse noise-induced hearing loss?

Continuous or one-time exposure to loud noise causes noise-induced hearing loss. It is also a type of sensorineural hearing loss. Prolonged exposure to noise damages the hair cells in the inner ear. Therefore, hair cells within the cochlea losses their ability to pick and transmit sound to the brain. Most of the time once the hair cells have been damaged, they are unable to restore again. Therefore, reverse noise-induced hearing loss is not possible. According to research by Stanford University of medicine hearing loss is reversible. The research leads to the development of surgical techniques and medication that could decrease the deafness and reverse it.

Losses are affected by noise-induced hearing loss, a recent CDC report states that in the US alone, approximately 25% of patients suffer from a noise-induced auditory impairment. So far, Frequency Therapists have acquired more than $ 30 million through their initial finance round to help reduce the number of sufferers.

According to the Frequency Therapeutics website, it has been estimated that approximately 1 billion people worldwide are suffering from hearing loss. Not only are Frequency Therapeutics exploiting a large scale market, but they are also working to solve a recurring pain point in the world market.


NIHL occurs due to exposure to the loud noise for a longer period of time. It damages the hair cell of the inner ear. .It is a type of sensorineural hearing loss. The unit of sound is Decibel dB. However, sounds greater than 85 decibels can cause hearing loss if exposure is longer.

Research on reverse noise-induced hearing loss –

Regeneration of hair cells – With some medication immediately after the blast, hearing damage is limited. This research will definitely overcome the degeneration of hair cells in the cochlea of the inner ear. Through this research probability of reversing the noise-induced hearing loss increases. Scientists are trying to achieve the goal and start the trial within ten years.

Researchers are looking for the solution which protects the hair cells of the inner ear from the damage. Basically, they are looking for the protective properties of the cells which help in reducing the damage.


Frequency Therapeutics has developed a method of treatment for noise-induced hearing loss, which uses progenitor cells, another advanced form of development for stem cells. Ancestor cells have been developed in more directed applications than stem cells which can be used for many different purposes.

The injection that Frequency Therapeutics has developed activates the use of these progenitor cells. Reprogramme inner year hair cells that detect fluctuations in air pressure and help to change into sound signals in the brain.


This hearing loss can be prevented with suitable methods. If you know how to protect the ear from noise. Some of the methods are

  • Enlist that sound which causes the damage to the hair cells of the inner ear.
  • Try to use earplug or protectives devices when exposing yourself in a nosy area.
  • Try to move away yourself from the noise, if you cannot control it.
  • Protect the ears of the infants because they are too sensitive.
  • Go for the hearing test on a regular basis.
