I've heard that sound travels better in water than it does in air. That why submarine can hear each other at such long distances. I was wondering what people thought about the impact of a radio playing in an aluminum boat might have on fishing. It seems like the aluminum would transfer the sound waves pretty efficiently into the water. Let's assume that the fish don't have a preference for country,rock,R&B, or sports. I'm curious about the affect of the sound waves themselves. Trains on railroad bridges don't seem to have all that much of an affect on the bite if they are already biteing.
