I work from home a few hours a week, and when I'm in my bedroom on the computer, I hear all sorts of interesting things. You see, I live 60 steps away from a pub, and 70 from Parramatta Road.
The dominant sounds are traffic and birds, which I don't mind.
The less dominant, although more arresting sounds are:
people yelling (usually alcohol induced)
motorcycle clubs blowing up
people coughing, vomiting or spitting.
My neighbour seems to have some form of pneumonia or emphysema which sounds pretty bad. Our apartment blocks are about 1.5 metres away from each other, and the sound echoes between them.
There's also a car dealership round the corner, and the employees come out for a smoko near my window, and one of them has a habit of hoicking spit globs up just when I'm settling down to write something. Nice!
I'm pretty happy living in the city, and without the occassional aural ambush, I think I'd be unsettled.
What do you hear where you live?
