Hearing Loss from Noise Exposure

Noise Induced Hearing Loss


When an individual is exposed to loud sound, the inner ear can become permanently damaged. This is known as Noise Induced Hearing Loss (NIHL). The longer one is exposed to loud noise, the greater likelihood of permanently damaging one’s hearing. The louder the sound, the less time it takes to cause damage to the inner ear.


Risks for NIHL include but are not limited to:

  • Working in noisy environments, such as industrial factories, musician venues, warehouses, military bases, or transportation vehicles (trucks, airplanes, ambulances,

  • Participating in activities such as shooting firearms or attending concerts

  • Listening to music at an extremely loud volume level for extended periods of time


Signs that may indicate NIHL include: 

  • Gradual or sudden hearing loss

  • Difficulty understanding people, especially in noisy environments

  • Sensitivity to noise (hyperacusis)

  • Ringing/humming in the ears (tinnitus)

  • Perception that pitch is off

  • Changes in heart rate

  • Disturbed sleep

  • Cognition and learning disorders


How might you prevent NIHL?

Limit exposure to noise! Be sure to wear hearing protection devices such as earmuffs, earplugs or musician plugs. You may also consider using sound-isolating earphones when listening to music to decrease background noise and avoid needing to make the volume louder


A term that has been widely surfacing in the Audiology world is known as Hidden Hearing Loss. This term has been applied to cases in which the patient reports difficulty with speech in noise, tinnitus and hyperacusis, though tests reveal normal hearing. Exposure to loud sounds for extended periods of time can lead to functional deficits before hearing loss is displayed on hearing tests. Even if hearing is normal, these symptoms could be a precursor to hearing loss when exposed to loud sound!
