English: Illustrations of sounds used during angular position discrimination – passive listening. Binaural recording of a click and click echoes made in EB's ears in the anechoic chamber, while he made clicks in the presence of a position marker located 150 cm 10° to the right of straight ahead. In the experiment sounds were presented via MR compatible headphones (Sensimetrics, Malden, MA, USA, Model S-14). To illustrate the sounds that participants heard through these headphones during the experiments, sample sounds have been passed through a 10 kHz low-pass filter. NOTE: We advise to use in-ear stereo headphones to listen to sound sample.
