How does NOISE effect us in everyday life?

When unwanted sound created by human beings hits our ears and disturbs the environment, noise pollution is created. Chiefly, noise pollution comes from barking dogs, loud music, vehicles, aircraft and rail transport, air-conditioners, factories, amplified music and construction work.
Sources of noise: All transportation systems create noise pollution. With residences created adjacent to factories, they experience noise pollution and its adverse effects. Besides transportation noise, noise can come from factory appliances, power tools and audio entertainment systems.
Measures of noise: Noise pollution is measured in decibels. When noise is at 45 decibels, no human being can sleep, and at 120 decibels the ear is in pain and hearing begins to be damaged at 85 decibels.
Effects of noise pollution
Human health: Noise pollution disturbs our health and behavior in a number of ways including deafness causing lack of sleep, irritability, indigestion, heartburn, high blood pressure, ulcers, and heart disease. Just one noise explosion from a passing truck drastically alters our endocrinal, neurological, and cardiovascular functions in many individuals. If this is prolonged or frequent, the physiological disturbances become chronic and contribute to mental illness.
Annoyance: Sometimes, even low levels of noise are irritating and can be frustrating, and high volumes can be annoying. Natural sounds are less irritating than those we find uncontrollable but intermittent sounds such as a tap dripping water can be more irritating than the sound of falling rain.

Here Are A Few Examples Of Sounds Effects on Education and Healthcare

Noise Levels In Education

Cognitive development is impaired when homes or schools are near sources of noise such as highways and airports.

Noise affects learning, reading, problem solving, motivation, school performance, and social and emotional development.

Children who live in noisy environments have been shown to have elevated blood pressures and elevated levels of stress-induced hormones.

 American National Standards Institute calls for a maximum ambient noise level of 35 dB.

 Many classrooms currently do not meet the recommendations of this standard, but at least one state, Connecticut, has already adopted the use of ANSI S12.60 for its schools.

Noise Levels In Healthcare

Excessive noise, and its effect on rest, are high on the list of complaints made by patients on post-discharge patient satisfaction surveys.

Excessive noise in health care settings can induce headaches, cause irritability, prolong wound healing and increase sensitivity to pain.

Noise levels in hospitals are twice what they were a few decades ago. They're approaching the level of harm, and they're definitely at the level of stress.

Health care is noisier than ever. Worldwide, the sound levels inside hospitals average 72 decibels during the day and 60 decibels at night — far exceeding the standard of 40 decibels or less, set by the World Health Organization.

 Did you know ... ? Tapping on the top of an incubator is equivalent to the sounds of heavy traffic during rush hour!

In her 1859 book "Notes on Nursing," Florence Nightingale railed against unnecessary noise, calling it "the most cruel absence of care."
