Exploiting ground effects for surface transport noise abatement

Exploiting ground effects for surface transport noise abatement

Abstract: Growing demand on transportation, road and railwaynetworks has increased the risk of annoyance from these sources and the need to optimise noise mitigation. The potential traffic noise reduction arising from use of acoustically-soft surfaces and artificial roughness (0.3 m high or less) is explored through laboratory experiments, outdoor measurements at short and medium ranges and pre...

Noise Abatement for Circular Saws

Sound propagation over soft ground without and with crops and potential for surface transport noise attenuation.

Growing demand on transportation, road, and railway networks has resulted in increased levels of annoyance from road traffic. Optimized use of green surfaces in combination with vegetation may be desirable as a method for reducing the noise impact of road traffic in urban and rural environments. Sound propagation over soft ground and through crops has been studied through outdoor measurements a...

Using natural means to reduce surface transport noise during propagation outdoors

This paper reviews ways of reducing surface transport noise by natural means. The noise abatement solutions of interest can be easily (visually) incorporated in the landscape or help with greening the (sub)urban environment. They include vegetated surfaces (applied to faces or tops of noise walls and on buildings’ façades and roofs), caged piles of stones (gabions), vegetation belts (tree belts...

Noise Abatement at Ben-Gurion International Airport

Ben-Gurion International Airport operates 24 hours at day for landing airplanes. The areas in vicinity of Ben-Gurion International Airport are very populated. The noise of the landing airplanes exceeds the common thresholds. This paper examines the current situation and suggests a possible solution.
