The forward momentum of a kite creates a low pressure area behind the sail. The low pressure area meets the high pressure area near the trailing edge and this causes the trailing edge to flap. A leach line can tighten the leading edge so it does not flap. Some kite fliers like to loosen the leach line, not to make a loud sound but because the flapping slows the kite down. This is usually done in competition to maintain the speed of the kite.

tcope,

I believe you meant that the leach line tensions the "trailing edge" of the kite.

kite_pilot,

The leach line works best if there is a slight amount of curve in the leading edge, from the upper spreader to the wing tip, which curve allows for a uniform tension of the sail to the trailing edge.  Without the slight curve in the leading edge, a tensioned leach line would cause the trailing edge to curve towards the front of the kite, introducing unwanted camber to the sail at this location.
