. In both analog and digital electronics, noise
is random unwanted perturbation to a wanted signal; it is called noise as a generalisation of the acoustic noise ("static") heard when listening to a weak radio
transmission with significant electrical noise. Signal noise is heard as acoustic noise if the signal is converted into sound (e.g., played through a loudspeaker
); it manifests as "snow
" on a television
or video
image.
A sound does not view itself as thought, as ought, as needing another sound for its elucidation, as etc.; it has not time for any consideration--it is occupied with the performance of its characteristics: before it has died away it must have made perfectly exact its frequency, its loudness, its length, its overtone structure, the precise morphology of these and of itself.
Music has no subject beyond the combinations of notes we hear, for music speaks not only by means of sounds, it speaks nothing but sound.
You know the sound of two hands clapping; tell me, what is the sound of one hand?
Could we not imagine that noise...is itself nothing more than the sum of a multitude of different sounds which are being heard simultaneously?
If a tree falls in a forest, and no-one is around to hear it, does it make a noise?
