Road traffic noise in agglomerations: How high are reduction potentials?

Heavy traffic on road in Hamburg; Photo: Matthias Hintzsche © UBARoad traffic in agglomerations is a major source of noise. It is also the area with the highest potential to reduce noise levels. Success in implementation of the noise action planning as required by the EU Environmental Noise Directive will depend largely on making use of the synergies of various different traffic and environmental protection plans. A study done on behalf of UBA has quantified the reduction potentials based on the example of the Hamburg agglomeration.

Long-term exposure to aircraft noise is recipe for illness

PassagierflugzeugPeople exposed to high levels of night-time aircraft noise often have higher blood pressure levels that those living in quieter residential areas. This is a finding from an international study in which the Federal Environment Agency participated. An increase in night-time aircraft noise by 10 decibels [dB(A)] within a noise level range between 30 and 60 [dB(A)] already raises the risk of hypertension in men and women by about 14 percent.

Many passenger cars as loud as 25 years ago

traffic jamAlthough noise limit values have been tightened repeatedly during the past few decades, many passenger cars are still as loud today as they were 25 years ago.  A practical test commissioned by the Federal Environment Agency revealed that while manufacturers made significant progress during this time period in the area of motor vehicle propulsion noise alone, today’s tires are hardly quieter on the road than 25 years ago.

Noise-based landing charges in effect at airports   

Passenger airplane at terminalAviation noise can be reduced by introducing landing charges based on aircraft noise emissions.  A study carried out by Öko-Institut on behalf of the Federal Environment Agency makes practicable recommendations for an effective system of noise-based landing charges that should be taken up in future.
