So you have come to see what we have to show for ourselves, eh? Please read the following disclosure before listening to our team’s synthesized 3D audio, so you can better understand the quality of your experience:
The manner in which any one individual perceives a synthesized 3D sound image is entirely unique to that individual, much like a fingerprint. The unique anatomical structures of your ear that are involved in sound reception determines how the synapses of your brain process the information. Since no two individuals can be characterized to hear the exact same way, it is then possible to say that a synthesized audio spatialization can be optimized, in some manner, to cater to the unique user.
At this stage in the project, we are utilizing a generic database developed by the University of California that characterizes various subjects and their method of “hearing” based off the anatomical structures of the subjects’ ears. We have uploaded 5 different subjects’ “method of hearing” from this database. They were chosen mostly because they were the best match for the unique members of this team!
We hope one of the following samples will fit you well, (but certainly not perfectly). One of the larger goals of the 3D Stereo Navigation project will be to cater this experience to the unique user using qualitative and/or quantitative methods. As for the algorithms behind the synthesis, that is all us! If you aren’t impressed right now, wait another 4 months and come back and try again. We also hope to deliver an interactive 3D Audio experience by the end of next semester, so stay tuned!
Elevation perception is highly sensitive to the shape of your ear, so a “bad fit” subject will have confusing elevations! The 3D effect is still there, but since your brain knows where these common sounds “should” be coming from, you will sense right away if something feels “wrong.” Our brains are used to hearing certain familiar sounds from certain elevations, so when this perception is toyed with, it is very noticeable!
