Intake noise is normal; it just shows you have "unrestricted" air flow that flows in such a way that it whistles.
Air leaks don't really affect the sound; they affect how the bike runs, so if you installed an air filter and the bike's reaction doesn't make sense, you might want to make sure you've sealed everything up right.
Personally, I like the "whistling" intake sound. Compliments the sound of the exhaust.
