Depends on what you like.

Most racetracks are out in the countryside.

I would certainly call a screaming and swearing airhorn- blowing football match crowd of 50,000 people 'noise pollution' .

The cars are quieter due to the new power plants, and all racetracks have noise limits put on the cars, depending upon what class they are competing in. I don't see much harm in 2 or 3 days F1 volume for a couple of hours once a year though.
