Hearing alert to convertible owners

Convertible owners who regularly drive with the top down are at risk of damaging their hearing, a new study suggests.

Scientists at the Saint Louis University School of Medicine in the US said these drivers exposed themselves to noises which were above the recommended limit of 85dB.

They said that the volume generated by travelling at 70mph is similar to that produced at the dance floor of a nightclub.

To avoid such noise affecting their hearing, they advised convertible owners to use earplugs or raise the roof for longer journeys.

Dr Anthony Mikulec, of the Saint Louis University School of Medicine, said: "We are recommending that drivers be advised to drive with the top closed when travelling for extended periods at speeds exceeding 52mph.

"Long duration driving at high speeds with the top open will increase the risk of hearing damage."
