Jesus f****ing Christ, boys and girls, could we PULLEEEEZE make sure we are
all talking about the same things, just maybe, huh?

Mr. Lee, you are absolutely correct, the velocity of sound is indeed about
300 m/sec (342 m/sec at STP, to be a bit more precise), but that has absolutely
not one wit to do with skin effect. Common, the original writer was making
a statement about electrical propogation in a cable, and what that has to
do with acoustical propogation is simple to understand: nothing!
