green landscape solutions for noise As suburban sprawl continues and traffic demands increase everywhere, more homeowners are faced with an annoying byproduct: noise. But there are numerous ways ...
Noise control is a set of strategies to reduce noise pollution by reducing noise at its source, by inhibiting sound propagation using noise barriers or similar, or by the use of ear protection (earmuffs or earplugs). [20] Control at the source is the most cost-effective way of providing noise control.

The END gives a common approach intended to avoid, prevent or reduce the harmful effects of environmental noise. The main target is an integrated noise management. In the first step the competent authorities in the European member states had to produce strategic noise maps for major roads, railways, airports and agglomerations. The second step ...
