English: Illustrations of sounds used during Outdoor Scenes Classification. Binaural recording of clicks and click echoes made in EB's ears in an outdoor setting, while he made clicks in the presence of lamp-post located in front of him (background sounds contain birds, leaves, etc.). 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.
