Entropy approach for mitigation of environmental aviation impact and airport capacity increase

The implementation of the operational procedures to reduce aircraft noise and engine emission in the airport vicinity was under consideration in the paper. Emphasis was put on optimal aircraft operational procedures for noise and emission reduction taking into account interrelations of aircraft noise and engine emission. The task of minimising of aircraft noise impact and engine emission ...

Case study - Use of the Nor848A acoustic camera on wind turbines

The acoustic camera system Nor848 is a powerful tool to investigate noise sources. In realtime you listen to a beamformed audio signal so that you can hear individual sources one by one. Immediately you can identify the strongest over all noise source in a multisource environment, and you can do the same analysis for single frequencies, 1/3 or 1/1 octave bands or any given frequency range. This ...

Required changes in emission standards for high-frequency noise in power systems

This paper discusses some recent developments that make the existing standards on the emission of high-frequency noise in power systems need to be reconsidered. It is shown that it is possible for an equipment to remain below the emission limits while at the same time the disturbance level increases beyond what was intended by the standard document. Further, the change from analog to digital ...

Case study - Nor848A Acoustic Camera Metro station in Taipei, Taiwan

After the construction of the elevated sky train, too high noise levels were appearing under the line and local communities were complaining. Therefore acoustic absorbing panels were mounted under the metro line at critical sites in order to reduce noise emission. To document the effect of the absorbers a Norsonic Nor848A 1.0 meter acoustic camera was setup for recording and reporting on the ...

Size, structure and distribution of transport subsidies in Europe

Transport contributes to several environmental problems such as climate change, air emissions and noise and is at the same time favoured by significant subsidies. An EEA report identifies European transport subsidies worth at least EUR 270 to 290 billion a year. Road transport receives EUR 125 billion in annual subsidies, most of it as infrastructure subsidies, assuming that taxes on road ...
