In this part of the database we collect results from psychoacoustic experiments run by the different labs involved in Two!Ears.
Coloration of a point source in Wave Field Synthesis¶
This database entry contains stimuli and results from the experiments described in [Wierstorf2014a]. In the experiment different WFS systems synthesising a point source were rated in terms of their perceived coloration compared to real point source. This was done for different audio material, namely pink noise, speech, and music and different listener positions. The results are summarised in Fig. 31 and available in the following database files:
experiments/sound_field_synthesis/coloration/human_label_center_positon_music.csv experiments/sound_field_synthesis/coloration/human_label_center_positon_noise.csv experiments/sound_field_synthesis/coloration/human_label_center_positon_speech.csv experiments/sound_field_synthesis/coloration/human_label_multiple_positions_music.csv experiments/sound_field_synthesis/coloration/human_label_multiple_positions_noise.csv experiments/sound_field_synthesis/coloration/human_label_multiple_positions_speech.csv
The corresponding stimuli are provided as BRS files that can be used together
with the Binaural simulator and the corresponding the corresponding scene description file
wfs_coloration.xml to reproduce the exact pink noise signals from the
test. The available BRS files are summarised in the
*.flist files that
simply provide listings of them.

For the following localisation experiments we provide again BRS files together with the rating results. The BRS files can be used together with the Binaural simulator on order to have the Two!Ears Auditory Model in the same situation as the listener including its ability to turn the head.
Localisation of a point source¶
In this experiment the localisation of a real point source realised by a loudspeaker was compared to the localisation of a binaural simulation of the same source using HRTFs or BRIRs. The results are published in [Wierstorf2012]. We do not provide the localisation results, but the head movements of the listener performed during the experiment together with the BRS files used for the binaural simulations of the point source.

Localisation of different source types in sound field synthesis¶
In this experiment listeners localised different synthesised sources using different sound field synthesis methods and loudspeaker setups. The experiment is described in [Wierstorf2014b]. Here, we are providing the BRS files that were used for binaural simulations of the different systems and listener positions during the experiment and the corresponding rating results of the listeners.
