[Lone Ranger]

I don't think it matters that much, although I wouldn't blast it for the rest of the fishermen to hear. Since water is about 5 times denser than air, anything that transmits sound directly into the water will impact the fishing. E.g. dropping or scraping a tackle box on the bottom of an aluminum boat or banging an anchor against the side of the boat. Sound waves from talking or playing music I don't think will be directed back into the water and to the fish.
