2007), and several companies now distribute termite acoustic detection instruments (Mankin 2011).
2012), it was of interest to consider the potential use of insect acoustic detection devices to help survey the magnitudes and locations of M.
Honolulu, HI, March 03, 2018 --(PR.com)-- IDS's New 3-D printable acoustic imaging and bathymetry technology has been selected for an innovation showcase at the upcoming US Navy Pacific Command's (USPACOM) Pacific Operations Science and Technology Conference (http://www.ndia.org/events/2017/3/6/2017-pacific-operational-science-and-technology-conference), IDS will conduct three technical presentations on operational space formation cube satellite chemical detection, identification, and imaging technology; acoustic detection identification, imaging and bathymetry technology; and crowd sourced littoral zone bathymetry technology.
The AVSs are practical and versatile acoustic measurement sensors, with applications in underwater acoustic detection. We provided an experimental investigation of five popular azimuth angle estimation methods, CAIM, WCAIM, CBF, MVDR, and MUSIC, upon a single AVS configuration.
Acoustic detection rates were higher than visual sighting rates; this is typical for joint visual/acoustic surveys, especially during poor sighting conditions (Thomas, Fisher, Ferm, & Holt, 1986; Fristrup & Clark, 1997; Norris, McDonald, & Barlow, 1999; Barlow & Taylor, 2005).
Long-range acoustic detection and localization of Blue Whale calls in the northeast Pacific Ocean.
Acoustic detection and classification of marine mammal calls require that animals produce sounds that 1) have sufficient amplitude to be detected in the presence of other sounds and 2) are species-unique to allow confident species identification.
The methods used for pipeline blockage detection usually including percussion sound method, pipeline strain method, hydraulic analysis method, mass-volume balance method, and acoustic detection method, through analyzing the acoustic signal which is based on acoustic detection method, have a lot of advantage [1], such as high sensitivity with no damage in pipeline equipment and high detecting speed.
Custom-built UAS could escape acoustic detection and would be virtually untraceable if it was recovered by authorities after a crash.
The researchers also attempted to use underwater acoustic detection technology to hear the calls of an unknown species of the beaked whale, but even after hours of tracking them, the team never saw the creatures.
