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…

Diagnostic Ultrasound Imaging: Inside Out
Farhat, G.; Toronto Univ., Toronto, Canada

Formato:	info:eu-repo/semantics/article, info:eu-repo/semantics/publishedVersion, ,
Enlaces:	The book is about diagnostic ultrasound imaging authored by Dr. Thomas L. Zabo. Graduate students in medical physics and biomedical engineering with backgrounds in calculus, complex numbers and some knowledge on electric circuits would benefit from this book.

Extraction of the vocal tract area function by external stimulus, Extraction de la Fonction d'Aire du Conduit Vocal par Excitation Externe
Teffahi, Hocine; Univ. Sci./Technol. Houari B., Lab. Commun. Parlee/Traitement Sign., Fac. d'Electron. et d'Info., BP 32, El alia, Alger, Algeria - Guerin, Bernard; Inst. de Communication Parlée, INPGrenoble, 46 Avenue Félix Viallet, 38000, Grenoble, France - Djeradi, Amar; Univ. Sci./Technol. Houari B., Lab. Commun. Parlee/Traitement Sign., Fac. d'Electron. et d'Info., BP 32, El alia, Alger, Algeria

Formato:	info:eu-repo/semantics/article, info:eu-repo/semantics/publishedVersion, ,
Enlaces:	Knowledge of vocal tract area function is important for the understanding of phenomena occurring during speech production. We present here a new measurement method based on external excitation of the vocal tract with a known pseudo-random sequence, where the area…

Array element localization of a bottom moored hydrophone array
Barlee, Matthew; School of Earth and Ocean Sciences, University of Victoria, Victoria, BC V8W 3Y2, Canada - Dosso, Stan; School of Earth and Ocean Sciences, University of Victoria, Victoria, BC V8W 3Y2, Canada - Schey, Philip; Space Naval Warfare Center (SPAWAR), 53560 Hull Street, San Diego, CA 92152-5001, United States

Formato:	info:eu-repo/semantics/article, info:eu-repo/semantics/publishedVersion, ,
Enlaces:	In ocean acoustics, rapidly deployable, autonomous, bottom moored hydrophone arrays allow for quick, cost effective deployment, but result in poor knowledge of sensor positions. Because advanced array processing techniques, such as Matched Beam Processing, are highly sensitive to errors in…
