# 3D sound reconstruction

3D sound reconstruction is the application of reconstruction techniques to 3D sound localization technology. [1]

## Acoustic location

Acoustic location is the use of sound to determine the distance and direction of its source or reflector.

## Cross section (geometry)

In geometry and science, a cross section is the non-empty intersection of a solid body in three-dimensional space with a plane, or the analog in higher-dimensional spaces.

## Dimension

In physics and mathematics, the dimension of a mathematical space (or object) is informally defined as the minimum number of coordinates needed to specify any point within it.

## Field (mathematics)

In mathematics, a field is a set on which addition, subtraction, multiplication, and division are defined, and behave as when they are applied to rational and real numbers.

## Head-related transfer function

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.

## Holography

Holography is the science and practice of making holograms.

## Laser Doppler vibrometer

A laser Doppler vibrometer (LDV) is a scientific instrument that is used to make non-contact vibration measurements of a surface.

## Medical imaging

Medical imaging is the technique and process of creating visual representations of the interior of a body for clinical analysis and medical intervention, as well as visual representation of the function of some organs or tissues (physiology).

## Military

A military or armed force is a professional organization formally authorized by a sovereign state to use lethal or deadly force and weapons to support the interests of the state.

## Reverberation

Reverberation, in psychoacoustics and acoustics, is a persistence of sound after the sound is produced.

## Signal reconstruction

In signal processing, reconstruction usually means the determination of an original continuous signal from a sequence of equally spaced samples.

## Sound

In physics, sound is a vibration that typically propagates as an audible wave of pressure, through a transmission medium such as a gas, liquid or solid.

## Sound intensity

Sound intensity level also known as acoustic intensity is defined as the power carried by sound waves per unit area in a direction perpendicular to that area.

## Sound pressure

Sound pressure or acoustic pressure is the local pressure deviation from the ambient (average or equilibrium) atmospheric pressure, caused by a sound wave.

## Three-dimensional space

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).

## Tomographic reconstruction

Tomographic reconstruction is a type of multidimensional inverse problem where the challenge is to yield an estimate of a specific system from a finite number of projections.

## Tomography

Tomography is imaging by sections or sectioning, through the use of any kind of penetrating wave.

## 3D sound localization

3D sound localization refers to an acoustic technology that is used to locate the source of a sound in a three-dimensional space.
