Noise. The world [is] for hearing... audible... Life is full of noise: work noise, noise of man noise of beast. Noise bought, sold, or prohibited. Nothing essential happens in the absence of noise... by listening to noise we can better understand ...what hope we may have. [1]

To retrieve memories: deposit them, one by one in a public space [2]

Sounds I hear:

• elements, wind, water, thunder, wind through trees,
• bird song, people: speech, song, music
• breathing, rushing of blood, heartbeat, whisper, speak, declaim, shout, hum, sing, whistle, fart, gurgle, play a musical instrument, operate machinery, bump into things, walk around, tap, thump, ruffle, click fingers, rub forefingers.
• recorded sound. mains hum, computer fans, electronic interferences between these multiple sources,
• bells, explosions includes internal combustion engines, traffic, railways, air craft.

Noise is information for the moment:

• meaningless [3], or
• inducing nausea - a confusion of the height, depth and width
• unimportant or threatening

We hear against a background of noise, from chaos, not from silence.

The difference between sound and noise is one of value: suitability, response, recognition.
