Audi R10: Your Neighbors Would Love It!

Let's just say that you were able to sign a multi-million dollar check for an Audi R10 TDI race car. This particular car, know as the "quiet" race car would definitely annoy your nbeighbors based on the 105db (decibel) output it creates. That being said, an interesting article following the possibilities are is below.



Here are a few excerpts:

According to www.dangerousdecibels.org, “serious” hearing damage occurs around the 105 decibel mark, which happens to be the R10’s noise output estimate, according to Ulrich Baretzky, Audi’s boss of race and special engine development. Baretzky said Audi has never measured the R10’s actual noise level, yet the diesel’s predecessor-the gasoline-powered eight-cylinder R8-put out around 110 dB. His R10 estimate came from combined tests of the cars and his knowledge of the two engines. He simplified the reasons for the five dB difference.....

.....So how loud does that make the R10,? While our eardrums rupture at 150 dB (or a jet-airplane takeoff), the R10 and R8 both come in under the human-pain threshold of 120 dB (a thunderclap). The R10 can best be compared to a jackhammer or other power tool, while the R8 is more similar to an ambulance siren. The five-fold gap between the two cars might seem significant on paper, but does a jackhammer seem significantly quieter than an ambulance siren? This raises the question about the accuracy of R10 ear-witness fans. Would you use the words jackhammer and “whisper quiet” in the same sentence? Maybe if you were an ambulance driver. And that’s where Baretzky claims the difference lies. Sound is relevant.....

.....“I’m really fed up with the screaming engines around here for 24 hours,” Baretzky said. “You cannot talk anymore [because] you have a sore throat after a half an hour.”
