^Once it comes through the wall it STILL has to go through air to your ears- and we have 2 to tell the direction of sound. Ive had enough noisy neighbors to tell you its super obvious which wall its coming through.
Not that its a big deal lol- just a minor point.
Yeah, but even with that transfer through air and the fact we have 2 ears doesn't mean our auditory senses can't be fooled.
Example from experience:
My and my brother's shared room is in between the living room and the kitchen, with the bathroom being right next to the living room (from above, our apartment has a shape resembling a deformed letter E, with the vertical line being a bit longer due to bathroom).
A few days ago, my dad called me for something (IDK what for). From how it sounded to me, I thought for sure that he was either in the living room or the bathroom, but he wasn't in either of those. As it turns out, the sound came from the opposite direction - the kitchen.
