2. Acoustic location - Wikipedia

   en.wikipedia.org/wiki/Acoustic_location

   Acoustic source localization [4] is the task of locating a sound source given measurements of the sound field. The sound field can be described using physical quantities like sound pressure and particle velocity. By measuring these properties it is (indirectly) possible to obtain a source direction.

3. Sound localization - Wikipedia

   en.wikipedia.org/wiki/Sound_localization

   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 ...

4. 3D sound reconstruction - Wikipedia

   en.wikipedia.org/wiki/3d_sound_reconstruction

   The obtained data is applied to the 5-speaker three-dimensional sound system, as in the listening room technique. The system also convolves the head-related transfer function with the impulse response from the signal recorded by the microphones and the energy is adjusted per the original time frame of the sound signal, and an additional delay ...

5. 3D sound localization - Wikipedia

   en.wikipedia.org/wiki/3D_sound_localization

   A general way to implement 3d sound localization is to use the HRTF(Head-related transfer function). First, compute HRTFs for the 3D sound localization, by formulating two equations; one represents the signal of a given sound source and the other indicates the signal output from the robot head microphones for the sound transferred from the source.

6. Perceptual-based 3D sound localization - Wikipedia

   en.wikipedia.org/wiki/Perceptual-based_3D_sound...

   While the relationship between human perception of sound and various attributes of the sound field is not yet well understood, [2] DSP algorithms for sound localization are able to employ several mechanisms found in neural systems, including the interaural time difference (ITD, the difference in arrival time of a sound between two locations), the interaural intensity difference (IID, the ...

7. 3D audio effect - Wikipedia

   en.wikipedia.org/wiki/3D_audio_effect

   A sound is placed in the horizontal plane by processing the sound with recorded head-related impulse responses. Using head-related transfer functions and reverberation, the changes of sound on its way from the source (including reflections from walls and floors) to the listener's ear can be simulated. These effects include localization of sound ...
