Using global optimization methods for three-dimensional localization and quantification of incoherent acoustic sources [PDF]
JASA Express Letters, 2022 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.
PLoS Computational Biology, 2010 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
SPIE Proceedings, 2017 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.

Characterization of In-Pipe Acoustic Wave for Water Leak Detection [PDF]
, 2011 This paper presents experimental observations on the characteristics of the acoustic signal propagation and attenuation inside water-filled pipes. An acoustic source (exciter) is mounted on the internal pipe wall, at a fixed location, and produces a ...
