Observations of surf infrasound in Hawai‘i
[1] Comparison of ocean buoy measurements with infrasonic array data collected during the epic winter of 2002–2003 shows a clear relationship between breaking ocean wave height and infrasonic signal levels. In addition, infrasonic arrays allow the identification of distinct breaking zones along the shoreline. Our observations suggest that infrasonic measurements can be used in conjunction with ...
متن کاملInfrasound Emission from Wind Turbines
A critical survey of all known published measurement results of infrasound from wind turbines has been made. The survey indicates that wind turbines of contemporary design with an upwind rotor generate very faint infrasound with a level far below the threshold of perception even at a rather short distance. From considerations on propagation and transmission of infrasound it is concluded that in...
متن کاملSurf Based Large Scale Image Retrieval
Image matching is the primary and important process which is mainly used in target tracking, space exploration, 3D reconstruction, modification identification. The existing system is utilizes the Scale Invariant Feature Transform (SIFT) is used to identifying corresponding points becomes difficult in the case of changing illumination or two surfaces with a similar intensity. Image retrieval ref...
متن کاملEvaluation of infrasound signals from the shuttle Atlantis using a large seismic network.
Inclement weather in Florida forced the space shuttle "Atlantis" to land at Edwards Air Force Base in southern California on June 22, 2007, passing near three infrasound stations and several hundred seismic stations in northern Mexico, southern California, and Nevada. The high signal-to-noise ratio, broad receiver coverage, and Atlantis' positional information allow for the testing of infrasoun...
متن کاملInfrasound from Wind Turbines Could Affect Humans
Wind turbines generate low frequency sounds that affect the ear. The ear is superficially similar to a microphone, converting mechanical sound waves into electrical signals, but does this by complex physiologic processes. Serious misconceptions about low frequency sound and the ear have resulted from a failure to consider in detail how the ear works. Although the cells that provide hearing are ...
