Low noise screens
A low noise screen compensates for its lower height (up to around 1 m) by increased proximity to the noise it is screening. The effect can be substantial in some cases1, but there are practical issues like maintenance and traffic safety to consider. Like high screens, low screens can be combined with creative solutions that incorporate water and vegetation to form part of an urban design solution.
