How does hearing loss occur?
Hearing loss can have many causes, including:
- Exposure to loud environments
- Physical damage such as a perforated eardrum or damage to the nerve endings inside the cochlea
- Abnormalities in the structure of the ear itself.
How can I help prevent hearing loss?
The easiest way to prevent hearing loss is to avoid unprotected exposure to loud noises, which can damage the nerve endings inside the cochlea.
Exposure to even moderately loud noise over a period of time can be damaging, and studies show that prolonged exposure to sounds at or above 90dB can damage your hearing. Sounds at this volume aren’t limited to industrial environments; they can be made by every day things like vacuum cleaners, lawnmowers, chainsaws or loud music.
In order to protect your hearing, wear earplugs whenever your surroundings are so loud that you have to raise your voice to be heard.
