Exposure to Loud Noises is Harmful Both for Human Beings and Other Creatures

Exposure to loud noises is harmful both for human beings and other creatures. If affects no only the physical health of human beings but also their psychological health.

Any unwanted sound that is loud enough to be unpleasant or to cause disturbance or annoyance is termed as noise pollution. Noise is generated by many human activities, especially those related to urbanization and rapid growth of transport and industry.

Noise pollution is a unique kind of pollution for two reasons.

• Noise pollution lasts only for a short time: - this is unlike air or water pollution, where pollutants remain in the environment when no new pollutants are released into the atmosphere. Once the sound stops, noise pollution stops too.

• Noise pollution is a matter of individual perception: what one person might consider noise pollution, the other person might not.

*-A loud speaker or a public address system cannot be used at night (between 10 PM to 6 AM), except in closed premises, for example, auditoria, conferences and banquet halls.

*Wearing earmuffs or cotton plugs, covering your ears with your hands, or simply moving away from the source of noise can protect you from the impact of noise pollution.

Apple Inc.’s ubiquitous I pod is best know as an instrument of solitude-unless the user ignores standards of etiquette by turning up the volume so much that it disturbs fellow commuters, officemates or other innocent bystanders. Besides many people sing along loudly or have loud conversations while listening to their iPods and disturb those around them.

Noise pollution makes the entire ecosystem speak louder eventually! Because of human induced noise in a creature’s natural habitat, it has to `speak’ louder to communicate to other members of its species. This is a Lombard Vocal response. For example, scientists have found that the length of whales’ sounds is longer when submarine-detectors are on. So, when one species begins communicating louder than normal, other species too have to speak louder, to be heard!

Impact of noise pollution

Exposure to loud noises is harmful both for human beings and other creatures. If affects no only the physical health of human beings but also their psychological health.

Hearing loss

Continued exposure to loud speakers can cause hearing loss among human beings and animals.

Heart diseases and high blood pressure

Heart diseases and high blood pressure are now proven to be related to exposure to loud noises. In fact, noise from aircraft can raise blood pressure even while one is asleep! Noise pollution causes stress in animals too.

Other impacts on health

Loud noises can lead gastrointestinal problems, annoyance, hypertension, loss of concentration, insomnia, chronic headaches, fatigue, aggressive behavior, and reduced work efficiency.

Impact on environment

As human encroachment of virus animal habitats continues and as creatures flee noisy areas, their natural habitats shrink, pushing them towards extinction.
