Question

Are there different levels of acceptable noise for children and adults? Discuss how noise pollution can contribute to stress. Name other forms of pollution. What are the challenges that these forms of pollution pose for the human body?

Answer 1

• Continuous exposure to hazardous levels of noise tend to affect high frequencies regions of the cochlea first. Noise induces hearing loss gradually, imperceptibly, and often painlessly.

In children prolonged exposure to sounds louder than 85 dBA is injurious (85 dBA is tolerable for an occupational exposure). It should never exceed 120 dBA.

In adults, impulse noise exposure, peak sound pressures should never exceed 140 dB.

• Noise pollution can trigger body’s stress response, one of its major health effects is chronic stress and the high levels of stress hormones that go with it.

• Other forms of pollution-
• Air Pollution.
• Water Pollution.
• Soil Pollution.
• Light Pollution.
• Radioactive Pollution.
• Environmental Pollution.

• Effect on human body-

Air pollution- Effect of air pollution on human health vary widely depending on the nature of pollutants. An irritant pollutant cause respiratory problems and cardiovascular diseases.

Water pollution- Water pollution cause diseases such as Diarrhea, Cholera, Typhoid, Dysentery, and skin infections.

Light pollution- Light pollution disturbs the circadian rhythm of humans.

Radioactive pollution- Mutation at the genetic level are caused due to this pollution which causes disease that can be caused by exposure to radiation.

Environmental pollution- Environmental pollution causes physical effects on humans. It often causes long term neurodegenerative effects. Diseases like allergies, asthma, irritation of eyes and nasal passage blockage are also some of the health implications of this pollution.
