Without going into too much detail, what is the difference between sound Amplitude & sound Intensity?

Question

Put as basic as possible without any form of maths, what would the answer be, apart from them having different names.

Answer 1

Intensity of any sinusoidal variation goes like amplitude squared. (So on a log scale, intensity is twice amplitude).

In sound, amplitude measures the actual pressure variation. Intensity measures the energy (which goes like pressure diff squared).

So if you know one, you know the other.

Answer 2

imagine two speaker a small one and a really huge one.
both can make sound with the same amplitude.( the conus moves 1 millimeter for both)

the intensity of the sound of the huge speaker is more, it is easier to shutdown the small speaker than the huge speaker
