Using global optimization methods for three-dimensional localization and quantification of incoherent acoustic sources [PDF]
Complex acoustic systems typically present three-dimensional distributions of noise sources. Conventional acoustic imaging methods with planar microphone arrays are unsuitable for three-dimensional acoustic imaging, given the computational demands and ...

Spike-timing-based computation in sound localization.
Spike timing is precise in the auditory system and it has been argued that it conveys information about auditory stimuli, in particular about the location of a sound source.

MEMS directional acoustic sensor for locating sound sources
The conventional directional sound sensing systems employ an array of spatially separated microphones to achieve directional sensing. However, there are insects such as Ormia ochracea fly that can determine the direction of sound using a miniature hearing organ much smaller than the wavelength of sound it detects.

Acoustic Emission Test of Changlongshan Pumped Storage Power Station Steel Bifurcation Pipe [PDF]
The maximum test load of Changlongshan pumped storage power station steel bifurcation pipe is 10MPa. To ensure the safety of the water pressure test, acoustic emission is used to monitor the main welds of the crescent rib steel bifurcation and main cone.

Passive Acoustic Source Tracking Using Underwater Distributed Sensors
Passive acoustic source tracking using underwater distributed sensors has been a severe problem because of the complexity of the underwater channel and the limited resources of the sensors.
