You're probably thinking: "What, golfing can't damage my hearing!" Well, newer thin faced titanium driving clubs all produced greater sound levels than conventional stainless steel clubs. In a study published in the December 2008 Sport issue of the British Medical Journal, BMJ 2008;337:a2835, Dr. Malcolm Buchanan found that his patient experienced hearing loss after using the King Cobra LD driver. The King Cobra also wasn't the loudest driver. Their results showed that thin faced titanium drivers produce sufficiently loud sound to induce temporary, or even permanent hearing damage in susceptible individuals. Caution should be used by golfers who play regularly with thin faced titanium drivers to avoid damage to their hearing.
