I tried earplugs designed specifically for motorsports at one of the loudest races in the world - here's the verdict

For the past few years, I've been rather frequently attending car races, and I've discovered that an indispensable piece of equipment is a set of earplugs.

As a member of the media, I usually have some sort of access to the pit stops, where the race cars pull in to get tire changes and to be refueled. The noise they make, up close, it literally eardrum-obliterating.

But even if you don't get down close to the action, the type of intense racket that race cars generate can be very bad for your hearing.

In the past, I've usually made do with disposable foam earplug, which dampen the wail of screaming engines, but also muffle everything else.

Then a company called Etymotic, which makes a range of earphones and hearing-protection devices, offered to let me sample a pair of ER-20 XS high-definition earplugs designed specifically for motorsports.

I had a great test in mind for the product: the 24 Hours of Le Mans auto race, held every June southwest of Paris in the French countryside.

How'd they do? Read on to find out:
