amplitude or instantaneous?
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?
|-! 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
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)
