Reportedly, ear plug sales are on the rise at shops in the area, and an Irish company is marketing a one-minute therapy that promises to alleviate the temporary ringing in the ears brought on by exposure to the vuvuzela.
The company, Restored Hearing, said in a news release that that its therapy involves using a low hum that helps get the vibration-sensing hairs in the cochlea, or inner ear, back into their original positions.
It claimed that so far, the therapy has a 99 percent success rate.
Gladstone had his doubts: "I'm skeptical, because I'm not aware of any research that supports this."
Both hearing experts say that anyone who has been exposed to the intense vuvuzela sounds over an extended period of time should monitor any changes in their hearing.
"If anybody experiences ringing, muffled sounds or has trouble understanding people speaking they should see an audiologist within a reasonable period of time if these symptoms persist," said Gladstone.
"It's common to have ringing in the ears afterward, but if it doesn't resolve in more than 36 hours, they should definitely seek attention," said Weigand. "You only have two ears, and you should protect them," he added.
