It would also redirect the sound fore & aft rather than let it spread...

Back in the 80's, I decided to try skydiving...Static line, Para-Commander, 4000 feet...Terrifying, but the biggest surprise was the total silence as you drift down...Nothing for the sounds to bounce off of...Nothing...I could see the Cessna circling, the guys on the ground, another skydiver drifting down...I tried shouting, even my own voice was muted...Quite an acoustical experience...
