Lead researcher Dr Malcom Buchanan, an ENT specialist and a keen golfer, said: "Our results show that thin-faced titanium drivers may produce sufficient sound to induce temporary or even permanent cochlear damage in susceptible individuals."
He said golfers should be careful when playing with these thin-faced clubs as they make a lot more noise, and suggested they could wear earplugs for protection.
Crystal Rolfe, an audiologist for the RNID, said: "Exposure to loud impulse sounds over time can cause damage. It is a short, sharp burst of very loud peak sound with this type of golf club.
"Earplugs would offer some protection and if someone was playing regularly with these types of club they might consider wearing them. But this is only one individual case so we need more research."
Dr Martin Strangwood, an expert in sports equipment engineering at the University of Birmingham, said manufacturers engineered the sound of the club to get a "good" sound for the player.
