This video actually has audio included of the action on a small piece of cloth (~1 inch circle) - I could not hear anything when it was drying.

I'm not sure that we can make an accurate judgement based on that because it's going to depend on the mic they used, audio codec, (and less relevantly), speaker setup and hearing of listener.
