I noticed when I was younger that I can "hear" when I'm near a wall, or just generally get a sense of the size of space I'm in solely via sound, but it never occurred to me to make a "ping" to sense the resulting sound reflections! Super interesting - I will have to try this. Probably my prior spatial sense from hearing was based on really subtle background noise of either my own footsteps or just environmental sounds reflecting around, I guess? I always felt like I am "hearing the room I'm in" but never quite knew how else to describe the sensation, but knowing people quite literally make a clicking noise to echolocate suddenly makes it much more clear!

Comb filtering (https://youtu.be/Amj4UevyRfU?si=5pwjHKwAw6bdmG2x https://youtu.be/Amj4UevyRfU?si=5pwjHKwAw6bdmG2x) plays a role in this. I was listening to a podcast and realized I could hear the speaker turning pages under the microphone by the way it affected their voice in the microphone rather than the rustle of the page. It was pretty wild. I could ‘see’ it before i recognized what was going on.

  Thanks for the video, I wouldn’t have guessed it shows well on a video. Kinda off topic but I’m on a brand new phone (not logged in and no history) and the next video suggested by YouTube is a French fascist promoting (actual) nazis policies. Why would YouTube do that?! It has absolutely zero connection with audio topics. I just have my OS language set to French. That’s so worrying for the youth with being exposed to pure hate for no reason.

    At a guess, it attracts two audiences - people interested in the content, and people aghast at the content. Twice the pulling power?

I did that, too, but I took it a bit further, possibly as a product of not having vision for about a year as a toddler, other than "light" and "dark."
