The distribution of mass in the club head made it less likely to twist, making an off-center hit less likely, but it had a drawback: a loud noise when it struck the ball, piercing through the tranquility of a golf course. The club never grew popular among players, with many saying they disliked the noise. Researchers set out to find the cause of the offensive clang.
