Sound Recognition

I have a small written journal that i have written about specific sounds. I try to focus on a new sound everyday and how i react to it. Thought about the sorrounding of the sound or voice. I live in the projects,,,,you know the "ghetto". and most sounds that are frequently heard are the sounds of car stereo systems, teenagers loud profanity to each other and a special feature of loading trucks of "Stop & Shop". There is really no silence...though at times silent is a noise itself. But the sounds that I've notice is the sound of a humming fridge, the rarely heard hissing of a heated radiator. and if you are very quite the thumbing of your temples. At first i was focusing on loud noises but when i paid much more attention to sound, i began to hear things that most people doesnt' pay attention to. My favorite sound thus far is my son's laughter every morning.
