Ultrasonics, 2014
In this article different techniques for localizing acoustic sources are described and the advantages/disadvantages of these techniques are discussed. Some source localization techniques are restricted to isotropic structures while other methods can be applied to anisotropic structures as well. Some techniques require precise knowledge of the direction

Acoustic source localization using the acoustic ENSBox
Proceedings of the 6th international conference on Information processing in sensor networks - IPSN '07, 2007Field biologists use animal sounds to discover the presence of individuals and to study their behavior. The recent development of new deployable acoustic sensor platforms presents opportunities to develop automated tools for bio-acoustic field research.

Acoustic localization in an ostariophysian fish
Experientia, 1977Under approximate free field conditions acoustic localization could be demonstrated in an ostariophysian fish, the ide (Leuciscus idus). The efficient vibration links of both succuli with the unpaired swimbladder (via the Weberian ossicles) do apparently not prclude directional hearing in this important group of freshwater fish.

Observability of acoustical and optical localization
Physical Review Letters, 1987Description quantitative de la localisation d'ondes acoustiques et optiques; expression de la longueur de localisation en termes de parametres experimentalement accessibles (densite et taille des elements diffusants, vitesse du son ou de la lumiere, frequence).

Acoustic Localization without Synchronization
2017 IEEE 31st International Conference on Advanced Information Networking and Applications (AINA), 2017In this paper, we design and implement an asynchronous multi-device acoustic localization system. Although the relative position and distance can be useful to many applications such as drone swarming, not much research has been conducted on the field.

Localizing Acoustic Objects on a Single Phone
IEEE/ACM Transactions on Networking, 2021Finding a small object (e.g., earbuds, keys or a wallet) in an indoor environment (e.g., in a house or an office) can be frustrating. In this paper, we propose an innovative system, called HyperEar , to localize such an object using only a single smartphone, based on enhanced time-difference-of-arrival (TDoA) measurements over acoustic signals issued ...

Localization of acoustic waves
Physical Review B, 1985The localization of sound waves moving in a random array of hard scatterers is studied for both two- and three-dimensional systems using a diagrammatic technique. For d=2 acoustic waves are found to be localized for all frequencies with the localization length growing exponentially for both high and low frequencies.

Localization in Virtual Acoustic Displays
Presence: Teleoperators and Virtual Environments, 1992This paper discusses the development of a particular spatial display medium, the virtual acoustic display. Although the technology can stand alone, it is envisioned ultimately to be a component of a larger multisensory environment and will no doubt find its greatest utility in that context.

Method of detecting localization of acoustic image and acoustic image localizing system
The Journal of the Acoustical Society of America, 1996A method of detecting localization of an acoustic image, in which an acoustic impulse is emitted from a sound source to a dummy of a human head, an acoustic sensor is provided to a portion of the dummy's ears, and the response waveform is received by the acoustic sensor.

Dynamic localization of acoustic waves in superlattices
Physical Review Letters, 1993The absorption and change in velocity of acoustic wave interacting with electrons in a superlattice irradiated by an infrared laser field are investigated. Near the roots of the equation s 0 /4d=|J 0 (eFd/Ω)| (24 and d are the miniband width and period of the superlattice, F and Ω are amplitude and frequency of the laser field, and so is the sound ...
