If a pulsar is a million light years away, why do we, on earth, receive a crisp, single "pulse" sound?

The fact that it's 'fanning out' makes no difference to us, as we only detect the signals that fall right into our detectors. It's like a machine gun spraying bullets across a battlefield. It doesn't matter where the others go, it's the one that hits you that you feel.
