Sound localization is a listener's ability to identify the location or origin of a detected sound in direction and distance. The sound localization mechanisms of the mammalian auditory system have been extensively studied. The auditory system uses several cues for sound source localization, including time difference and level difference (or ...
Acoustic location is a method of determining the position of an object or sound source by using sound waves. Location can take place in gases (such as the atmosphere), liquids (such as water), and in solids (such as in the earth).
3D sound localization refers to an acoustic technology that is used to locate the source of a sound in a three-dimensional space.The source location is usually determined by the direction of the incoming sound waves (horizontal and vertical angles) and the distance between the source and sensors.
The location of a sound source is determined through three-dimensional sound localization using multiple microphone arrays, binaural hearing methods, and HRTF (head-related transfer function). After identifying the direction, other signal processing techniques are used to measure the impulse response over lengths of time to determine the ...
The ILD arises from the fact that, a sound coming from a source located to one side of the head will have a higher intensity, or be louder, at the ear nearest the sound source. One can therefore create the illusion of a sound source emanating from one side of the head merely by adjusting the relative level of the sounds that are fed to two ...
These were automatically sent to a control post where they were automatically collated and the location of the sound source calculated. Prototypes of the new system, HALO (Hostile Artillery LOcating) were used in Sarajevo in 1995. The production system, ASP (Advanced Sound Ranging Project), entered British service in about 2001.
The acoustic propagation paths as understood at the time, operating depths of submarines and ray tracing for sound velocity conditions as understood in the Atlantic determined that the sound source depth should be at 1,000 m (3,280.8 ft) to 1,050 m (3,444.9 ft) with a center frequency of 400 Hz.

In atmospheric sounding and noise pollution, ambient noise level (sometimes called background noise level, reference sound level, or room noise level) is the background sound pressure level at a given location, normally specified as a reference level to study a new intrusive sound source. [1] Ambient sound levels are often measured in order to ...
