Prevention of Hearing Loss
You need to have a proper understanding of noise. For example, an extreme noise which is associated with a firecracker, experienced at close distance can lead to permanent hearing loss. Continuous exposure to machines and engines can slowly reduce your hearing power. If you are aware of the fact that you are going to be in between dangerous noise, wear earplugs. Don't purchase noisy appliances when there are other options available. Make sure that you never stick a hairpin and cotton swab in your ear to get rid of the earwax.
