There is a particular noise I hear on quite a few songs and I can't figure out exactly what's going on, but here's an example.

Can be heard at around 0:04 as an example, it occurs many times in the song. I'm not sure if it's a harmonic or what.. but the guitar is strummed as if it were just muted notes.

Any help would be appreciate thanks

Muted strings on the natural harmonics' positions. I'd say around 3rd fret.
