Road Traffic Noise - Factors modifying its relation to annoyance and cardiovascular disease
Traffic noise causes annoyance and sleep disturbance and has been linked with several other adverse effects on life quality and health, including increased risk of hypertension and myocardial infarction. Conservative estimates assume that at least one million healthy life years are lost every year …

Road traffic noise barrier design : measurements and models concerning multiple-walls and augmented earth mounds
… programme is concerned with the design of road traffic noise barriers, in particular, the use of multiple-walls on the ground and on top of earth mound type barriers.</p> <p>As part of this research, a comprehensive up-to-date review of the research carried out on noise barriers was …

Application of cepstrum techniques and a guard tube to the measurement of the normal incident sound power absorption coefficient of road surfaces in-situ
… plane wave sound power absorption coefficient of road surfaces in-situ. Road traffic noise has been identified as the greatest noise pollutant in the industrialised world with the tyre/road interaction being the major source of noise for traffic speeds in excess of 50 km/hr. Open pore bitumen …

Sonic Crystal Noise Barriers
An alternative road traffic noise barrier using an array of periodically arranged vertical cylinders known as a Sonic Crystal (SC) is investigated. As a result of multiple (Bragg) scattering, SCs exhibit a selective sound attenuation in frequency bands called band gaps or stop bands related to the …

Tranquillity by design - Architectural and landscape interventions to improve the soundscape quality in urban areas exposed to aircraft noise
The noise emissions from aircraft negatively impact the quality of life for those in areas around airports. Excess noise levels can cause stress-related complaints, leading to adverse health effects. Although newer aircraft are significantly quieter than older models, aircraft noise pollution …
