little

He ran his fingers slowly back and forth along the length of it, stroking it lovingly, and the shiny paper wrapper made little sharp crackly noises in the quiet room.

In the sentence, is the noise was made or heard? Otherwise, that means it hardly made noise?
I learned that 'little' tend to imply 'almost nothing', but I'm not sure.

The wrapper made noise, and presumably he (or an undefined narrator or reader) heard the noise, but the sentence really doesn't unambiguously say anything about the latter.

Thank you Mxsmanic.

I'm still unsure, though.
What do you think that the writer is trying to say? Is the writer tryting to say 'there was sharply crackly noises in the quiet room' or 'the noises were too quiet to be noticed even in the noiseless room'?

Sounds like an erotic story to me LOL

It's hard to say what the author intended, since he or she doesn't explicitly say what his intentions were. All you really know is that the wrapper made noises, and that the noises were little, sharp, and crackly.
