Environmental footprint of aircraft noise exposure at Cape Town International Airport
Airport ; Cape Town ; Geographical information system ; Man-environment relations ; Noise ; Nuisance ; South Africa ; Vulnerability
The paper provides a background sketch to the development of Cape Town International Airport and the noise control framework. It provides a brief overview of noise measurement and the way in which GIS is employed to determine the noise footprint
and manifestations of human exposure and also to establish the potential noise exposure of variously defined sensitive land use categories and vulnerable population groups in the noise-affected area. - (AJC)

A questionnaire survey was carried out among the residents of Debrecen (E-Hungary), according to which, it can be referred to as a noisy town of Hungary. Disturbances caused by road traffic, being the foremost source of noise, are evident throughout
, especially along the main transport routes. The duration of noise nuisance experienced in residential areas is considerable combined with the noise at workplaces and in the street. The effects of perceived noise nuisance on the quality of life is represented
by occasional or regular (not necessarily frequent) sleep disturbances, primarily among the residents living near roads with heavy traffic. Based on the results of the survey, by applying a noise complaint index, the spatial pattern of the level of noise
nuisance was drawn along with a cognitive noise map revealing the noisiest locations within the town. - (AM)

Using spectral analysis to detect sensor noise and correct turbulence intensity and shear stress estimates from EMCM flow records
This paper demonstrates the usefulness of spectral analysis to detect and characterize narrow-band noise components in turbulent flow records. Statistical principles underlying the use of spectral analysis for noise detection are briefly reviewed
. Examples of u and v velocity spectra and cospectra are then presented from actual EMCM velocity records from flume and field deployments that were found to be contaminated by such noises. The sensivity of the shear stress estimates to even minor noise
Measurement of bedload gravel transport: the calibration of a self-generated noise system

Self-generated noise (SGN) is a passive acoustic technique for the measurement of bedload transport through the acoustic detection of intergranular collisions using a submerged hydrophone system. SGN is of interest because of the possibilities
Contribution à la valorisation de l’eau dans les espaces urbains durables : l’exemple de Hà Nội (Việt Nam)
Hà Nội
important dans la planification et le développement durable de la ville. Hà Nội est une ville vietnamienne née de l’eau. Avec plus de mille ans d'histoire, les espaces en eaux ont toujours été disponibles et visibles, le linéaire bleu constituant la trame
Hà Nội. Cette thèse permet de clarifier le rôle et la valorisation de l'eau dans la formation et le développement de la ville de Hà Nội, de démontrer l'importance de l'eau dans la gestion et de la planification urbaine au Việt Nam en général et à Hà
Nội en particulier et enfin de proposer des scénarios urbains qui peuvent intégrer davantage de surfaces en eau dans le cadre d’une urbanisation durable. En outre, l'étude a également confirmé l’hypothèse selon laquelle l’eau est en mesure de

In the ascertainment of disturbing environmental influences the noise-maps may give an important contribution. Beginning with the practical application of noise-maps, the A. formulates 7 questions concerning the necessary informational planning
of noise-maps. This fundamental idea is followed by an informative survey of hitherto used forms of representing the spreading and distribution of the soundlevel on maps, hereby 7 chief types are discernible. The A. proposes four map-sheets, which should
be textually explained and illustrated with cartographic examples. In this way the elaboration and practical use of noise-maps is recommended.
