Effectiveness of control measures (管制成效)line分享列印本頁

A. Ambient noise and traffic noise non-compliance rates:

According to EPA statistics from 2000 to 2009, the ambient noise non-compliance rate dropped from 40% to 12%. The traffic noise non-compliance rate dropped from 6% to 2%, clearly demonstrating the positive effects of noise control measures undertaken by the EPA and local EPBs. From 2010 to 2013, the non-compliance rate was reduced from 3.8% to 0.8% for ambient noise and from 0.6% to 0.2% for traffic noise.

B. Motor vehicle noise control: 

For the approval of new vehicle models, stricter motor vehicle noise level standards will be gradually implemented. In response to global trends in the noise control legal framework, drafts of Phase 5 and Phase 6 were announced in 2014 and are due to take effect in 2015 and 2017, respectively. Since 2010, the EPA has implemented yearly in-use vehicle noise campaigns and has strengthened in-use vehicles roadside investigations conducted jointly with local EPBs, police departments, and motor vehicles management authorities. From 2011-2013, a total of 2,787 vehicles were inspected and approximately 40% were non-compliant with stationary noise control standards.

C. Low frequency noise control:

Control of low frequency noise arising from business and recreational premises has been enforced since July 1, 2005. At the end of 2009, a total of 18,235 cases were inspected nation-wide. Non-compliance with low frequency noise level standards was found in 1,590 cases. The non-compliance rate for low frequency noise cases was 8.7%, about 2 times more than the non-compliance rate for overall noise level standards.

This indicates that low frequency noise indeed has had an adverse impact on people's lives and reinforces the importance of extending the scope of noise control standards to include low frequency noise.

In 2013, non-compliance with low frequency noise level standards was found in 291 cases, or 6.2% of 4,665 inspected cases.

Since low frequency noise is highly penetrable, it is more difficult to assess the level of nuisance that it causes. As a result, the EPA requires local EPBs to reinforce noise improvement plans.
