noise emissions News

Speed constraints for aircraft are put in place, at some airports, to minimise noise pollution in local areas, however, such practices can be very fuel-inefficient. New research has now shown that relaxing departure speed limits could substantially reduce CO2 emissions, while maintaining acceptable noise levels. The aviation industry is a major contributor to emissions of greenhouse ...

Whilst living in cities, near airports or road and rail links, might prove useful for the commute, the noise levels can sometimes be too much to bear. A growing body of research reveals, transport noise can cause sleep disturbance, cardiovascular disease, elevated hormone levels, psychological problems and even premature death; studies on children have identified cognitive impairment, worsened ...

There is good news for anyone living near or under a flight path of one of the UK’s airports this week. A report out from the Airport Operators’ Association (AOA) shows that UK airports are reducing noise pollution and carbon emission despite growth in passenger numbers. The AOA was keen to publish the report in response to political and ...

As a major contributor to greenhouse gases, the transport sector figures high on the international climate change agenda. But for many living in cities, under flight paths or near major road and rail links, it's another of transport's by-products that causes most immediate harm: noise. Clearly, transport noise's long-term impacts fall a long way short of the apocalyptic projections for unabated ...

Air pollution is the world’s largest single environmental health risk. Unprecedented infrastructure activities, industrialization and heavy traffic are the main threats which increase the risk of respiratory and cardiovascular diseases. Noise-monitoring stations have been installed across the UAE to control the sound level in the cities. Restrictions were imposed on working hours and the ...

After a twenty-year wait, the European Commission has today proposed new standards to cut noise levels from cars, vans, buses and lorries. Reacting to the proposal, Nina Renshaw, deputy director at Transport and Environment, said: “While this proposal is a welcome move in the right direction, it should have gone farther and faster. The vast majority of cars for sale already meet step 1 of ...

IMMISmt is a real time monitoring system for air quality and noise. Based on online traffic data, measurements of air quality stations and weather data, IMMISmt calculates traffic induced emissions, background and total pollutant concentrations as well as noise levels within the streets as, e. g., hourly mean values. To do so, IMMISmt combines various models which are validated and widely used in ...

Traffic noise has suddenly moved up the EU agenda, with the Commission promising to cut noise from cars, vans, buses and lorries within five years. A proposal due later this year is expected to seek to reduce car noise by four decibels and lorry noise by three. The issue of noise has lagged behind EU efforts to cut air pollutant emissions, but a recent study suggesting that the benefits of ...
