Sound is essential to our daily lives, but NOISE is not.
Noise is generally unwanted sound, or sound which produces unpleasant effects and discomfort on the ears, e.g. vehicle horns, loudspeakers etc.
NOISE POLLUTION AFFECTS BOTH HEALTH AND BEHAVIOR.
Noise pollution can cause hypertension, cardiovascular issues, high stress levels, tinnitus, hearing problems, trouble communicating, sleeping disorder, and other harmful effects. Sadly noise also has a huge effect on pets – making them fearful and or more aggressive in households where there is constant noise.
CAUSES OF NOISE POLLUTION
1. Industrialization - big machines, compressors, generators, exhaust fans, grinding mills etc.
2. Poor Urban Planning – Leads to congested houses, large family’s sharing small spaces which lead to frequent fights over basic amenities, parking etc. – this noise pollution disrupts the environment and society.
3. Social Events: Noise is at its peak in most of the social events e.g. marriages, parties, pub, disco's or place of worship.
4. Transportation: Large numbers of vehicles on roads, Air planes/helicopters flying over houses, underground trains, all produce heavy noise.
5. Construction Activities - mining, construction of bridges, dams, buildings, stations, roads etc. takes place in almost every part of the world on an ongoing basis - too noisy.
6. Household- household gadgets such as mixers, grinders, pressure cooker, vacuum cleaners, washing machines, dryers, air conditioners, music sound systems, TV’s etc.
7. Household animal – constant barking.
Effects of Noise on Wildlife
Wildlife populations around the globe continue to diminish in size, due to the impacts of human encroachment and environmental pollution. Human-induced noise pollution is one of many factors contributing to the depletion of wildlife populations.
Studies performed indicate:
Hearing loss, due to high noise levels
loss of habitat and territory
loss of food supply
behavioural changes in mating predation and migration
changes in interspecies relationships
masking, which is the inability to hear important environmental cues and animal signals
increased heart rate and respiration and general stress reaction
Altered predator-prey balance, increased competition for food and shelter
