amplitude or instantaneous?
[edit]this article plays fast and loose with the concepts of instantaneous particle displacement vs particle displacement amplitude. Is "δ" really supposed to be used for both? is there a recommended way to differentiate the two?
c=speed of sound?
[edit]|- ! c | m/s || Speed of sound |-
Isn't that supposed to be speed of light? Thγmφ (talk) 04:09, 19 January 2010 (UTC)
- In a Humpty-dumpty way, it means whatever you want it to mean. It meant one thing to Albert Einstein: in acoustics it means another thing. How many different things can be represented by letters in scientific equations ? How many letters are there, even counting capitals and Greek ?

ISO 80000 standards
[edit]ISO 80000 standards recommend using δ for sound particle displacement, not ξ. — Preceding unsigned comment added by 2604:2000:C5B1:4200:3C3A:EA8C:4A49:18D3 (talk) 14:15, 2 August 2015 (UTC)
