Noise annoyance not sufficiently reduced

Target

4.5 By 2020, noise annoyance will be reduced by 10% from the 1999 level. By the same year the number of people exposed to indoor noise levels exceeding 38 dB will be reduced by 30% from the 2005 level.

Indicator

Total noise annoyance measured by the noise annoyance index for all sources measured, especially industry, motor sport and shooting ranges

Are we moving in the right direction? Published by the Norwegian Environment Agency

In 2006, the Norwegian Parliament adopted a target concerning a 10 per cent reduction in noise annoyance by 2020. The target is related to the part of the population in Norway that was exposed to noise in 1999. Statistics Norway has estimated the development from 1999 to 2014 for this part of the population. Due to reductions in noise from railways, industry and aviation there was a decrease in noise annoyance of 9 % during this period.

This indicator does not take into account those who have moved into noise-exposed areas or areas that have had a significant increase in noise levels after 1999. Thus, the indicator does not accurately reflect the number of people exposed to noise in Norway today.

Less noise from railways, industry and aviation

Reduced traffic, quieter trains and rail grinding are major causes for the reduction in noise from railways. Less noise annoyance from aviation is related to less noisy aircrafts as well as changes in procedures for landing and take-off at some airports.

Road traffic - the largest source of noise pollution

Road traffic is the major source of noise pollution in Norway. More traffic contributes to increased noise from road traffic, but improvements in engine and tire technology helps to curb the rise in noise annoyance.
