A comparison was carried out between the new approach and the in situ method using microphones.
Students as avatars discussed the problem in Second Life using microphones.
In the last decade, some papers were published which introduce 2D sound source localization methods using just two microphones in indoor cases using TDE -and ILD-based methods simultaneously.
Figure 8 Setup of the proposed 3D sound source localization method using four microphones.
Valin et al.[14] proposed a localization and tracking of simultaneous moving sound sources method using eight microphones and this method is based on a frequency domain implementation of a steered beamformer along with a particle filter-based tracking algorithm.
We first compared various conventional methods using observed signals in the case of two sources and two microphones.
The reciprocity calibration method uses two microphones acoustically connected by a coupler, a cylindrical cavity closed at each end by the diaphragms of the transmitting and receiving microphones.
This means the actors use microphones.
To capture individual vocalisations in a group setting, we used microphones mounted directly on the birds (on-bird microphones), and hereby chose microphone transmitters (Sparrow System, Fisher, III, USA).
