Hearing the sounds around you amplified 'equalizes' them, every sound takes on the same value, whether it is children running around or the sound of your own footsteps. All hierarchy is gone and at first this can be quite confusing. I was never aware how much hearing influences your spatial awareness.
Listening to your surroundings this way removes you from the sound-sources and submerges you in them at the same time.
The sound in the shopping centre contrasted with the sound in and around the estate. Walking up a stairwell the sound of the road next to it came in and out of focus. There were a lot fewer sounds directly generated by people, the only two I came across were a man working on his car and two boys playing football in a garden. Although most of the sounds I recorded were either manmade or industrial there was also birdsong, wind and rustling leaves.
