NASCAR to quiet the cars?

The rumble of the cars on NASCAR tracks could grow quieter under a proposal reported Monday that would allow fans to more easily communicate during races. The proposal is among 15 to 20 changes currently being studied by NASCAR, according to The Sports Business Journal. The sounds emitted by the stock cars is one of the allures of NASCAR, but the constant roar of the cars --- which is usually around 100 decibels during races --- makes communication difficult and the use of ear plugs a must among many fans. Messages left with NASCAR representatives by USA TODAY Sports were not immediately returned Monday. Cutting down on the noise race cars emit would be a serious undertaking and changes to the exhaust system could become pricey.
