Sound Walk

In the Stairwell:

Shoe squeaks

Lady talking

Echoes make it hard to tell how many people are inside the stairwell
Beeps and bangs from construction site can be heard, but they are "filtered" through the parking garage area which turns a lot of sounds into rumbles

Outside:

Two kinds of sounds really. Things that blend in to this overall sound and things that stand out. The construction equipment, the hum of car engines, birds, people walking, etc. all blend together.
Bus hisses, people dropping things at the construction site, unusually loud cars, etc. all stand out.

Littlefield:
Walking in there's this sort of relief to escape the loud hum of the street.

Replaced by a higher pitch blend of clinks and scrapes

Walking out there's another relief as we enter a quieter area.

Outside again:

Away from the street the sounds feel relaxed.

Less sound so there's less of a rumbled blend
