Chaos: An Interdisciplinary Journal of Nonlinear Science, 2002
Synchronized chaotic systems are highly vulnerable to noise added to the synchronizing signal. It was previously shown that chaotic circuits could be built that were less sensitive to this type of noise. In this work, simple chaotic maps are demonstrated that are also less sensitive to added noise.

Participatory sensing allows for a person-centric approach to gathering environmental measurement data with, in principle, high gran- ularity in space and time. Here we report on a citizen science experiment for noise mapping a 1 km2 area in the city of Antwerp using NoiseTube, a participatory sensing framework for monitoring ambient noise.

Image noise-informative map for noise standard deviation estimation
2011 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2011The problem of automatic detection of image areas that can be reliably selected for accurate estimation of additive noise standard deviation (STD), irrespectively to processed image properties, is considered in this paper. For getting accurate estimate of either texture or noise parameters involved, we distinguish two complementary image informative ...

The Role of the Noise Maps for the Noise Management in the Cities
Applied Mechanics and Materials, 2015The paper presents the application of noise maps in cities to reduce the traffic noise level on the streets. The division of noise maps, noise indicators for the evaluation of these maps as well as software systems used for creating noise maps are described in this paper.

The application of noise maps for traffic noise reduction
Noise Control Engineering Journal, 2011Using a computer model, a traffic noise map was prepared for a 1-km section of one of the most frequently travelled roads in Istanbul. Calculations were carried out in grid intervals of 10 m at 4 m above ground level. Field measurements were also conducted for the same region. The traffic noise map and noise level measurements are compared. Predictions

Noise reduction for progressive photon mapping
ACM SIGGRAPH 2012 Posters on - SIGGRAPH '12, 2012We present an adaptive noise reduction technique for progressive photon mapping, which preserves the consistency of the original algorithm. Although progressive photon mapping converges to the correct result in the limit, the image produced after a finite number of samples can suffer from both bias and noise [Hachisuka et al. 2010].

Mapping of Noise by Using Gis in ŞAnliurfa
Environmental Monitoring and Assessment, 2006Traffic noise results from highways where the most important source of noise in cities. This noise has the properties of linear source. Constitution of noise maps has become compulsory to see the regions that are influenced from the noise, and to put forward the future environmental approaches. During the mapping of the noise, generally two fundamental

3D noise mapping in urban areas
International Journal of Geographical Information Science, 2008Noise mapping is the process of determining and visualizing noise impact on the environment in order to support environmental policies. Currently most noise impact studies are based on a 2D approach. The 3D output of noise simulation software is processed and visualized in 2D and combined with 2D topographical and other data, such as population ...

Mapping the noise in a Greek general hospital
Science of The Total Environment, 2019Sound pressure levels were monitored in a general hospital, in Greece, at ten indoor locations and at three outdoor locations, in the yard of the building. The selected indoor locations are representative of distinct activities that are common in every hospital, such as the emergency department, patient wards and several supporting services, like ...

THE MILAN AGGLOMERATION STRATEGIC NOISE MAP
8th European Conference on Noise Control 2009, 2008The aim of this paper is to describe the procedure used for the Milan agglomeration Strategic Noise Mapping, as defined by Environmental Noise Directive (2002/49/EC). City of Milan is a complex case study because of the presence of a plurality of sources: road traffic, railway traffic (also tram traffic) and aircraft noise (Linate airport).
