Noise is a term often used to refer to an unwanted sound. In science and engineering, noise is an undesirable component that obscures a wanted signal. However, in sound perception it can often be used to identify the source of a sound and is an important component of timbre perception (see below).
Banging sounds coming from the Titan search zone briefly raised hopes, before the rising submersible was confirmed to have been destroyed in a ‘catastrophic implosion’. What was the banging ...
