| Major
sources |
Methods
of pollution |
| Road
traffic |
- increasing community reliance on road
transportation, and a reluctance to accept partial solutions involving
greater use of public transport
- land use planning has not been well
integrated with transport planning, allowing residential developments
and major transport corridors to occur in close proximity without appropriate
buffer zones or treatment to buildings
- increasing community reliance on road
transportation, and a reluctance to accept partial solutions involving
greater use of public transport
- land use planning has not been well
integrated with transport planning, allowing residential developments
and major transport corridors to occur in close proximity without appropriate
buffer zones or treatment to buildings
- traffic on many existing roads through
built up areas has increased well beyond expectations prevailing
during planning or constructions of the roadways
- inconsiderate
drivers speeding at the same time honking uncontrollably for no
apparent reason, which terms this drivers as road bullies
|
| Air
traffic |
- military
air force training with war planes and fighters flying at inappropriate
late hours at low flying altitude in close proximity to residential
areas
- increased numbers of commercial flights
over the years to accommodate the increasing demand to the number of
passengers throughout the world
- flight
path taken through densely populated area causing disturbances and
interfere with the tranquility of the environment
|
| Rail
traffic |
- construction of rail infrastructure
involves in drilling and other heavy machineries which emits loud and
deafening noises
- maintenance of rail infrastructure needs
to be checked and done in order to ensure the safety of the rail
involves the replacements of old platforms, trains and foundation
using heavy machineries emitting loud noises
- operation of trains increasing everyday,
especially during festivities in which it is operational for 24 hours
- use of petrol and diesel engines in
poorer countries than the quieter electric train and also older
version of rolling stock
- unsuitable
stopping pattern and topography which can lead to localized problem
where the noise concentration is high in a particular area
|
| Neighborhood
and domestic noise |
-
close
proximity of home with each other without a good sound barrier often
results in neighbors to endure the noises made
-
outdoors
which includes barking dogs repeatedly during nighttime where the
whole neighborhood is calm
-
lawn
mowing, car alarms and other social gathering at the lawn creating
noises
|
| Incompatible
land use |
- improper determination of land zoning
where heavy industrial sites are not separated from residential areas
by light industries, resulting in noise disturbances in the
residential area
- frequent
changing land uses over many decades have resulted in unacceptable
noise level for some areas and uses
|
| Industrial
noises |
- heavy machineries mechanisms during
combustions produces deafening sounds
- mining and dredging also results in
increase noise level involved
- extractions
of pure metals in coke ovens under high pressure
- electrical
components manufacturing and fertilizer
plants
