Loud noise or sound causes loss of hearing acuity / partial deafness. This is permanent and cannot be cured. The effect on those who have suffered a substantial amount of hearing loss is dramatic. They find it difficult to understand what other people are saying. Others have to speak loudly or shout to be heard, and this causes frustration, embarrassment and annoyance. It means that the TV has to be turned up loud and this can cause annoyance and arguments with others in the family, plus annoyance to neighbours.
It also spoils enjoyment of music.
Loud noise also causes permanent tinnitus, which is a ringing, buzzing or rushing sound in the ears that is always there and never goes away. Many people find this unpleasant and annoying. Tinnitus can make it difficult for people to get to sleep because it is most noticeable in a quiet environment. There is no cure for hearing loss or tinnitus caused by exposure to loud noise / sound. Hearing aids can help, but they do not normally provide the full quality of hearing that was enjoyed prior to damage by loud noise. Also, people find hearing aids a nuisance to wear. Many people are embarrassed about wearing them - some are too embarrassed to wear them and struggle on without them.
Common sources of loud noise include discos, concerts, live bands and some other forms of amplified music or speech. For people who work in factories, industrial machines are another major cause of loud noise.
Noise can also cause nuisance. This occurs at much lower sound levels than noise that causes hearing damage. It can keep people awake at night, disturb concentration, spoil enjoyment of music, television and ruin the peace and quiet. Very common causes of noise nuisance include dogs barking, neighbours’ music, parties, loud speech and laughter, and fans or air conditioning units at offices, shops and industrial factories.
