A closet recording, very low volume. The door was shut completely. If you use headphones, full-ear headphones, you'll feel the house absorb the sounds made by the kids and neighbors next door.
Something that provokes me to think more deeply into sound-as-image. If you ask someone to think of a sound, they can readily replay it in their head- if they're familiar with that sound. And one readily forms an image in their mind when provoked to think about a particular sound. If one asks another to think of a car horn, one will immediately form the image of a car or some such association.
It's not hard to grasp that a sound can create an image, and vice versa. All the senses are in symbiosis. To think otherwise, to delineate between the functions, is to fall prey to the Cartesian hoodwink.
