Researchers have recently made a breakthrough in the effort to understand the cause of noise-induced hearing loss. Nearly 15% of American adults experience some form of hearing loss, most of which is caused by prolonged exposure to loud noises. This discovery could be a key to learning how to protect hearing in other ways.
The Role of Zinc
The study conducted by researchers at the University of Pittsburgh revealed that during exposure to loud noise, excess zinc in the body concentrates around the ear’s inner ear hair cells. Usually, most zinc in the body is bound to proteins, but approximately 10% is free-floating. After traumatic levels of noise, the free-floating zinc becomes disregulated in the hair cells in the cochlea, disrupting communication between sensory cells in the inner ear. The findings of the study suggest that in the future, inner ear damage and hearing loss could be protected by targeting the excess zinc.
Protecting Your Hearing
While this research progresses, it’s still important to take steps to protect your hearing from exposure to loud noises. Consider the following to safeguard your hearing in the future:
- Limit noise exposure: Limit time in noisy environments. Or, when possible, take breaks in quieter areas during shows.
- Use hearing protection: Earplugs and other forms of hearing protection are effective at minimizing noise exposure during flights, concerts at Mars Music Hall, or while using loud tools.
- Monitor volume: Heed your personal device’s volume warnings and try to keep headphone volume low.
- Maintain a schedule of regular checkups: Getting your hearing checked regularly allows for timely intervention in the case of hearing loss.
This research is a step forward in understanding how noise-induced hearing loss occurs and opens new avenues for prevention and treatment. By recognizing the role of zinc in this process, scientists are closer to developing therapies that could one day protect people from hearing loss due to excessive noise. Until then, taking proactive steps to minimize noise exposure remains the best defense against hearing damage.
Additionally, if you’re experiencing hearing loss, hearing aids are a great tool to reconnect you with others and promote social well-being. To learn more about how you can benefit from hearing aids or to schedule a hearing test, contact North Alabama ENT Associates to schedule an appointment.
