This has been brought up before, although not directly relating to what passes and what doesn't. Here's my answer from that thread.

Also, neither Guinness nor Laguna Seca's site listed how they measured, so I'll assume it's at 1 meter, since that's the standard.

Since decibels change on a logarithmic scale that requires double the power for a 3 dB increase and half the power for a 3 dB decrease, then 1/8 of an adult German shepherd will produce 91 dB and be legal to run at Laguna Seca.

Math, bitches.
