Noise pollution
Effects
-
-
Excessive adrenalin in blood stream, which is reposnible for high blood
Muscle contraction that leads to nervous breakdowns, tension, etc.
Change in hormone levels , which increases heart rate, digestive spasms.
Affects work efficiency, behaviour.
Can damage the heart brain, kidneys, liver and causes emotional disturbance
Hearing impairment that diminishes part of the auditory system. Can lead to chronic damage to the inner ear
-
affects optical system, pupillary dilation, impairment of nght vision, decrease in rate of colour perception
-
Solutions
Noise barriers - over 3,000 km of noise barriers have been installed alongside European rail networks. They are even more widely used alongside roads in Austria, France, Poland, etc.
Break blocks for trains - decibel reduction 8-10db; A complete ban on noisy cast iron blocks is due to take place in Germany, Netherlands and Switzerland by 2020
Building insulation - 10-15 db - it is unclear how widely acoustical architectural planning is used.
-
Changing driving styles - 5-7 db. - quiter driving could be incorporated into existing campaigns promoting eco-driving to save fuel and reduce air pollution
Quit road surfaces - 3-7 db - low-noise surfaces are used in Denmark, the UK, etc. It implies using crumb rubber from end-of-life tyres, following a circular economy approach
-
Land-use planning and design - computer models can predict noise exposure and identify areas unsuitable for development.
-
Traffic management - 1-4 db. - these strategies are widely used across Europe. In Paris and Valencia there is restricted access for heavy good vehicles
