Take St. Petersburg, Florida, where a recent Indy Car race was held, for example. The most pressing issue for many St. Pete residents was the sound. Indy cars are very loud and the raucous racing took place from 8:30 AM until about 5:00 PM each day. Depending on where residents live, decibel (dB) levels reached from 110 to 122. How loud is 122 dB? A typical conversation occurs at about 60 dB.
