Ocean Acoustic Observatory Federation Acoustics
2015/8/5
The Ocean Acoustic Observatory Federation (OAOF) includes several laboratories and universities: the Institute of Geophysics and Planetary Physics (IGPP) and the Marine Physical Laboratory (MPL) at th...
Sounds in the Sea: From Ocean Acoustics to Acoustical Oceanography
Acoustical Oceanography Ocean Acoustics
2015/7/23
My review copy came with the following note attached:
Dear Reviewers of Sounds in the Sea:
Some of us have the audacity to believe that ocean exploration is more important to mankind than space exp...
Building on Fisheries Acoustics for Marine Ecosystem Surveys
Marine Ecosystem Surveys Fisheries
2015/7/20
The National Oceanic and Atmospheric Administration Marine Fisheries Service endeavors to manage fish stocks with an ecosystem perspective. This objective requires an understanding of the effects of t...
The Tibetan singing bowl: acoustics and fluid dynamics
Tibetan singing bowl acoustics fluid dynamics
2011/7/7
We present the results of an experimental investigation of the acoustics and fluid dynamics of Tibetan singing bowls. Their acoustic behavior is rationalized in terms of the related dynamics of standi...
Exterior cloaking with active sources in two dimensional acoustics
Active cloaking Acoustic waves Helmholtz equation Green’s formula
2010/12/3
We cloak a region from a known incident wave by surrounding the region with three or more devices that cancel out the field in the cloaked region without significantly radiating waves. Since very litt...
Tomographic Maps of the Ocean Mesoscale. Part 1：Pure Acoustics
Tomographic Maps Ocean Mesoscale Pure Acoustics
2009/1/15
A field test of ocean acoustic tomography was conducted in 1981 for a two month period in a 300 km square at 26°N, 70°W in the North Atlantic (just south of the MODE region). Nine acoustic deep-sea mo...
The inverse problem of finding the refraction coefficient of a shallow ocean from the observation of the extra Cauchy data for the acoustic field at the surface of the ocean is studied. Uniqueness the...
This article investigates as to how the Indian Drums are able to produce harmonics. In particular, it looks at the density distribution on an Indian Drum, the Tabla, and shows that it is the form of t...
