My Car Radio Is Louder Than Yours

If car racing is not for you, you can always compete for who has the loudest and most expensive car audio system.  From April through September contestants congregate at the Columbus Motor Speedway for a race of the biggest and baddest sound systems.  Levels of 140 to 160 decibel are the goal, writes the Columbus Dispatch. Pain begins at 125 dB, 140 dB are considered the highest recommended exposure, even with hearing protection. The race has four different sanctioning bodies. One of them, the Mobile Electronics Competition Association, sanctions 112 events in 18 states. from The Truth About Cars http://www.thetruthaboutcars.com
