Toward Noise Modelling in Urban Areas
2008 Second Asia International Conference on Modelling & Simulation (AMS), 2008Noise field measurements are the only precise method of estimating environment pollution. They are long-term and expensive and are not applicable in case of prediction of conditions caused by the new intervention in space. Independent of the bases of available data, which are sometimes very limited, and of the choice of calculation method for reliable ...

Compressive noise radar for urban sensing
2014 IEEE 8th Sensor Array and Multichannel Signal Processing Workshop (SAM), 2014Ultra-wideband (UWB) noise-like transmit waveforms are ideally suited for implementing compressive radar range-profile imaging systems. Due to useful properties such as robustness to interference, simplicity of hardware design, and high range resolution, UWB noise radar has been successfully applied to urban-sensing scenarios.

Urban indices as environmental noise indicators
Computers, Environment and Urban Systems, 2011Abstract The objective of this paper is to analyze the noise levels of an urban area by treating them as a function of several features resulting from block shapes and urban indices in a residential neighborhood of a medium sized Brazilian city. Inside this area a sample of 40 reference points was chosen for data collection and their noise levels ...

Evaluation of Noise Pollution in Urban Parks
Environmental Monitoring and Assessment, 2006The present study provides an evaluation of noise pollution in six Urban Parks located in the city of Curitiba, Brazil. Equivalent noise levels (L(eq)) were measured in 303 points (each point measured during 3 min) spread throughout the Parks. Measured values were confronted with local legislation (Law 10625) allowed limits, and the Parks were thus ...

Investigation and analysis of urban noise for sustainability
Proceedings of Meetings on Acoustics, 2008The concept of urban sustainability involves complex issues such as civil services, social participation, resilience, productivity, health, and development into a multilevel approach of environmental, social, and productivity sectors. Viewing environmental noise as part of urban dynamics is essential.

Noise belongs to the severest environmental impairments in towns, with road traffic being the most annoying noise source. The reduction of these impairments and the precaution against new noise impacts is an important task of the communities. However, many of the potential abatement measures are not in the responsibility of the communities.

Noise in the Urban Environment
Journal of the Urban Planning and Development Division, 1975Noise has so permeated and increased in urban environments, that to counter it for the sake of public health, governments and municipalities are limiting the output of the various sources. All means of transportation are being noise regulated, and some progress has already been made; but transportation is the city's circulatory system, and how its net ...

Birds and Anthropogenic Noise: Are Urban Songs Adaptive?
The American Naturalist, 2010In cities with intense low-frequency traffic noise, birds have been observed to sing louder and at a higher pitch. Several studies argue that higher song pitch is an adaptation to reduce masking from noise, and it has even been suggested that the song divergence between urban and nonurban songs might lead to reproductive isolation.

Current levels of noise in an urban environment
Applied Ergonomics, 1973In 1961, the International Organization for Standardization prescribed upper tolerance limits for noise generated out-of-doors in residential districts. Between 1963 and 1970, vehicular traffic in the UK increased in volume by approximately 40%. This paper describes studies made throughout 1971 in which both peak and ambient noise-levels prevailing ...
