Hearing loss can't always be prevented, sometimes it's just due to the nature of aging. However, hearing loss due to loud noise exposure (nose induced hearing loss- NIHL) is completely avoidable.
There are few tips to avoid noise-induced hearing loss.
Generally, a noise is probably loud enough to damage your hearing if:
Noise levels are measured in decibels (dB): the higher the number, the louder the noise. Any sound over 85dB can be harmful, especially if you're exposed to it for a long duration.
Example of sound that over 85 dB :
Listening to loud music through earphones and headphones is one of the biggest dangers to your hearing in this era.
To help avoid damaging your hearing:
By turning down the volume a little bit can make a big difference to your risk of hearing damage.
To protect your hearing during loud activities and events (such as at nightclubs, gigs or sports/shooting events):
If you're exposed to loud noises through your work, please communicate with your human resources (HR) department or superior.
Your employer is obliged to make changes to reduce your exposure to loud noise – for example, by:
Make sure you wear any hearing protection you're given.
Get a hearing test as soon as possible if you're worried you might be losing your hearing. The earlier hearing loss is picked up, the earlier something can be done about it.
You might also want to consider having regular hearing checks (once a year, say) if you're at a higher risk of noise-induced hearing loss – for example, if you're a musician or work in noisy environments.
