In a second experiment, the illusory stimulus was looped continuously in headphones while participants identified its perceived path of motion to test properties of perceptual switching, locking, and biases. These results show that this illusion is effectively quadri-stable. Participants perceived all four illusory motion percepts, and could not distinguish the illusion from the unambiguous stimuli. When asked to rate their confidence in perceiving each sound’s motion, participants reported equal confidence for the illusory and unambiguous stimuli. Here we demonstrate how human listeners experience this illusory phenomenon by comparing ambiguous and unambiguous stimuli for each of the four possible motion percepts.
The sound can be perceived as traveling transversely from front to back or back to front, or “bouncing” to remain exclusively in front of or behind the observer. Here, we introduce a novel quadri-stable illusion, the Transverse-and-Bounce Auditory Illusion, which combines front-back confusion with changes in volume levels of a nonspatial sound to create ambiguous percepts of an object approaching and withdrawing from the listener. However, the human auditory system has unequally distributed spatial resolution, including difficulty distinguishing sounds in front vs. One way we estimate the motion of an auditory object moving towards or away from us is from changes in volume intensity. Pretty awesome! Unlike the other videos, this one is best when used with speakers, rather than headphones.In addition to vision, audition plays an important role in sound localization in our world. Princeton invention delivers 3D sound from ordinary laptop speakersĮdgar Choueiri, a professor of mechanical and aerospace engineering at Princeton University, has developed a way to play three dimensional sound recordings from a standard stereo laptop speakers. This is a similar example of binaural 3D audio as the hair cut, and whilst getting a virtual shoe shine might not be the most exciting thing in the world, the potential for this technology is pretty amazing.ĥ. 3D Shoeshine (Binaural - Wear Headphones) Close your eyes and you can almost feel the barber’s breath on the back of your head.Ĥ. This is one of the most famous examples of 3D sound effects using stereo headphones. Whilst we might not be thrilled at the idea of a Grateful Dead fan coughing to the back of our head, it could be pretty cool for auditoriums with particular acoustics.ģ. Virtual Barber Shop Hair Cut - 3D Sound This interesting use of binaural technology – where two microphones are placed in the ears of a dummy head – replicates the experience of being in the audience during a live musical performance. This audio-only play utilises binaural 3D sound to tell a creepy story that places you in the centre of the action, using nothing more than a standard headphone. Thanks to a clever recording technique known as binaural recording, that places two microphones inside a dummy head where the ears are, you can get immersive surround sound on any pair of stereo headphones.ġ. The Interrogation Chamber - Amazing Binaural 3D Sound Play You don’t need expensive 7.1 virtual surround sound headphones to experience 3D sound.
