English: Illustrations of sounds used during Outdoor Scenes Classification. Control sound for Sound S12. This sound contains background sounds very similar to those in Sound S12, as the recording was also made in EB's ears in an outdoor setting while he stood in front of the lamp post. However, during the recording EB was silent. The click-like sounds in the audio file are Pseudo-clicks derived from EB's own clicks but placed in the same positions as the original clicks in Sound S12 (see Methods S1). Thus, the control sound is yoked to the Sound 12, but does not contain click-echoes. 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.
