Validation of large scale noise exposure modelling by long-term measurements

open access: yesNoise Mapping, 2017
Large scale noise exposure modelling is used in epidemiological research projects as well as for noise mapping and strategic action planning. Such calculations should always be accompanied by an assessment of uncertainty, on the one hand to check for ...

Multidimensional Speckle Noise Model [PDF]

open access: yesEURASIP Journal on Advances in Signal Processing, 2005
One of the main problems of SAR imagery is the presence of speckle noise, originated by the inherent coherent nature of this type of systems. For one-dimensional SAR systems it has been demonstrated that speckle can be considered as a multiplicative noise term.

Quantum model of spin noise [PDF]

open access: yesJournal of Magnetic Resonance, 2015
Any ensemble of quantum particles exhibits statistical fluctuations known as spin noise. Here, we provide a description of spin noise in the language of open quantum systems. The description unifies the signatures of spin noise under both strong and weak measurements.

Noise landing charges and passengers' choice of airport. [PDF]

open access: yes, 1995
This study demonstrates how aircraft noise can be translated into a form of landing charge. The objectives of the thesis were to develop noise landi'ng charges for six of the major airports in England and to determine what the implication it has on ...

Acoustic mitigation of noise in ports: an original methodology for the identification of intervention priorities

open access: yesNoise Mapping, 2022
The paper presents an original methodology for the identification of intervention priorities through a tailored priority index IP in areas that are highly-exposed to port noise. The methodology is applied to a case study developed in the framework of the
