Acoustic source localization with environmental uncertainty
Dosso, Stan E.; School of Earth and Ocean Sciences, University of Victoria, Victoria, BC V8W 3P6, Canada - Wilmut, Michael J.; School of Earth and Ocean Sciences, University of Victoria, Victoria, BC V8W 3P6, Canada

Formato:	info:eu-repo/semantics/article, info:eu-repo/semantics/publishedVersion, Conference Proceedings, Actes de congrès
Enlaces:	A nonlinear Bayesian formulation is applied to study uncertainty in ocean acoustic source localization due to uncertainty in the knowledge of ocean environmental properties. Localization uncertainty is quantified in terms of probability ambiguity surfaces (PAS), which consists of joint marginal…

On estimating sound power from a few single point measurements
Richarz, Werner; Pinchin Environmental, 5749 Coopers Ave, Mississauga, Ont. L4Z 1R5

Formato:	info:eu-repo/semantics/article, info:eu-repo/semantics/publishedVersion, Conference Proceedings, Actes de congrès
Enlaces:	The features of sound pressure measurements over reflective ground for compact source radiating broad-band noise, are described. The nature of a sound field generated by a broad-band source located above a reflecting surface, is also described. The mean-square sound is…

Infrasound from wind turbines - Fact, fiction or deception
Leventhall, Geoff; Noise and Vibration Consultant, 150 Craddocks Avenue, Ashtead Surrey KT21 1NL, United Kingdom

Formato:	info:eu-repo/semantics/article, info:eu-repo/semantics/publishedVersion, ,
Enlaces:	Infrasound is discussed in terms of what it actually is, how the media has dealt with it and what those with limited knowledge say about it. The perception of infrasound occcurs at levels higher than the levels produced by wind…

Changes to iso standards and their effects on machinery noise declarations
Keith, Stephen E.; Healthy Environments and Consumer Safety Branch, Environmental and Radiation Health Sciences Directorate, Consumer and Clinical Radiation Protection Bureau, 775 Brookfield Rd. 6301B, Ottawa, ON KlA lCl, Canada - BIy, Stephen H. P.; Healthy Environments and Consumer Safety Branch, Environmental and Radiation Health Sciences Directorate, Consumer and Clinical Radiation Protection Bureau, 775 Brookfield Rd. 6301B, Ottawa, ON KlA lCl, Canada

Formato:	info:eu-repo/semantics/article, info:eu-repo/semantics/publishedVersion, Conference Proceedings, Actes de congrès
Enlaces:	The article describes recent improvements in the basic ISO standards for measurement of machinery noise and how they can affect the ease of determination, or the reliability, of machinery noise declarations. Improvements to the ISO standards could be incorporated into…

Objets sonores: une représentation bio-inspirée, hiérarchique, parcimonieuse à très grandes dimensions utilisable en reconnaissance, Objets sonores: une représentation bio-inspirée, hiérarchique, parcimonieuse à très grandes dimensions utilisable en reconnaissance
Brodeur, Simon - Rouat, Jean; Groupe de recherche en Neuroscience Computationelle et Traitement Intelligent des Signaux (NECOTIS) Département génie électrique et génie informatique, Université de Sherbrooke, Sherbrooke QC Canada J1K 2R1

Formato:	info:eu-repo/semantics/article, info:eu-repo/semantics/publishedVersion, ,
Enlaces:	The emphasis is put on the hierarchical structure, independence and sparseness aspects of auditory signalrepresentations in high-dimensional spaces, so as to define the components of auditory objects. The conceptof an auditory object and its neural representation is introduced. An illustrative…
