Based on the background that I have studying acoustics scientifically at the collegiate level...this is not a fair comparison.
For one...sound is not "just" sound. Remember the hapless mayor in Ohio who proposed moving deaf people to neighborhoods near the airport? The folks that are hard of hearing reminded everyone that they can still FEEL sound even if they can't HEAR sound.
Feeling sound is important here: the compression waves provided by drum kits (or at a greater extreme, gunshots) are a significant force....way more powerful than a force that can be generated by the human voice, or tossing ordinary household objects around. People will hear and feel the drum kit more, and for greater distances. The drum kit looked as if it were miked...which would enhance the effect even more.
People will hear and feel the drum kit more, and for greater distances than they would an ordinary television (By ordinary television, I mean a television with the stock 10 or so watt speakers....and not the 2000 watt home theater surround sound.) In addition, everyone recognized the drum kit as a sound that shouldn't be there.
That looked like a decent middle class complex...one where televisions would be commonplace. That did not sound like a sound that shouldn't be there. That could have been an audio clip from CSI Miami, Netflix, a TV commercial for an upcoming movie, the 11pm news, something from youtube or facebook.
I listened to the clip 3 times. I did not hear anything that said "MURDER" instead of "MEDIA." :idunno:
