A simple video camcorder with audio capability could assist in answering this question.
I do however like the way this old phrase was used by great Canadian songwriter, Bruce Cockburn. He uses it to point out that people need more awareness of what the globalists are doing to our natural resources in the area of forestry. He is using the phrase as a symbolic jesture to bring attention to this issue.. Of course in this view, "does anybody hear", could easily be changed with "does anybody care".
