Acoustic location is the use of sound to determine the distance and direction of its source or reflector.
Acoustical engineering (also known as acoustic engineering) is the branch of engineering dealing with sound and vibration.
Acoustics is the branch of physics that deals with the study of all mechanical waves in gases, liquids, and solids including topics such as vibration, sound, ultrasound and infrasound.
In computer science, the analysis of algorithms is the determination of the computational complexity of algorithms, that is the amount of time, storage and/or other resources necessary to execute them.
An audio signal is a representation of sound, typically as an electrical voltage for analog signals and a binary number for digital signals.
Beamforming or spatial filtering is a signal processing technique used in sensor arrays for directional signal transmission or reception.
Binaural recording is a method of recording sound that uses two microphones, arranged with the intent to create a 3-D stereo sound sensation for the listener of actually being in the room with the performers or instruments.
Bionics or Biologically inspired engineering is the application of biological methods and systems found in nature to the study and design of engineering systems and modern technology.
In signal processing, cross-correlation is a measure of similarity of two series as a function of the displacement of one relative to the other.
In statistics, an expectation–maximization (EM) algorithm is an iterative method to find maximum likelihood or maximum a posteriori (MAP) estimates of parameters in statistical models, where the model depends on unobserved latent variables.
A frog is any member of a diverse and largely carnivorous group of short-bodied, tailless amphibians composing the order Anura (Ancient Greek ἀν-, without + οὐρά, tail).
A head-related transfer function (HRTF) also sometimes known as the anatomical transfer function (ATF) is a response that characterizes how an ear receives a sound from a point in space.
A hearing aid is a device designed to improve hearing by making sound audible to a person with hearing loss.
High frequency (HF) is the ITU designation for the range of radio frequency electromagnetic waves (radio waves) between 3 and 30 megahertz (MHz).
The interaural time difference (or ITD) when concerning humans or animals, is the difference in arrival time of a sound between two ears.
Low frequency (low freq) or LF is the ITU designation for radio frequencies (RF) in the range of 30 kilohertz (kHz)–300 kHz.
Mammals are the vertebrates within the class Mammalia (from Latin mamma "breast"), a clade of endothermic amniotes distinguished from reptiles (including birds) by the possession of a neocortex (a region of the brain), hair, three middle ear bones, and mammary glands.
In statistics, maximum likelihood estimation (MLE) is a method of estimating the parameters of a statistical model, given observations.
A microphone array is any number of microphones operating in tandem.
Monaural or monophonic sound reproduction (often shortened to mono) is sound intended to be heard as if it were emanating from one position.
Multilateration (MLAT) is a surveillance technique based on the measurement of the difference in distance to two stations at known locations by broadcast signals at known times.
MUSIC (MUltiple SIgnal Classification) is an algorithm used for frequency estimation and emitter location.
Navigation is a field of study that focuses on the process of monitoring and controlling the movement of a craft or vehicle from one place to another.
The term neural network was traditionally used to refer to a network or circuit of neurons.
In the broadest definition, a sensor is a device, module, or subsystem whose purpose is to detect events or changes in its environment and send the information to other electronics, frequently a computer processor.
Signal processing concerns the analysis, synthesis, and modification of signals, which are broadly defined as functions conveying "information about the behavior or attributes of some phenomenon", such as sound, images, and biological measurements.
Sonar (originally an acronym for SOund Navigation And Ranging) is a technique that uses sound propagation (usually underwater, as in submarine navigation) to navigate, communicate with or detect objects on or under the surface of the water, such as other vessels.
Sound localization is a listener's ability to identify the location or origin of a detected sound in direction and distance.
Three-dimensional space (also: 3-space or, rarely, tri-dimensional space) is a geometric setting in which three values (called parameters) are required to determine the position of an element (i.e., point).
Two-dimensional space or bi-dimensional space is a geometric setting in which two values (called parameters) are required to determine the position of an element (i.e., point).
3D sound reconstruction is the application of reconstruction techniques to 3D sound localization technology.
