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.

Psychoacoustic modelling of rotor noise [PDF]

open access: yesThe Journal of the Acoustical Society of America, 2022
The aviation sector is rapidly evolving with more electric propulsion systems and a variety of new technologies of vertical take-off and landing manned and unmanned aerial vehicles. Community noise impact is one of the main barriers for the wider adoption of these new vehicles.

Shot-noise queueing models [PDF]

open access: yesQueueing Systems, 2021
AbstractWe provide a survey of so-called shot-noise queues: queueing models with the special feature that the server speed is proportional to the amount of work it faces. Several results are derived for the workload in anM/G/1 shot-noise queue and some of its variants.

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 ...

Urban noise model

open access: yesThe Journal of the Acoustical Society of America, 1974
A model has been developed for predicting median levels of traffic noise in a variety of local conditions. Sound sources are grouped into two categories: major thoroughfares with average daily traffic volume greater than 5000 vehicles are considered individually as line sources with uniform distribution of traffic and all other streets are grouped into
