How quiet does my car or motorcycle have to be to run at AMP?
Arizona Motorsports Park has set a maximum limit of a 94.0 dB for any vehicle operating at AMP.
How do I know how loud my car or motorcycle is?
AMP is periodically holds “Sound Certification Days” for the purpose of testing vehicles. If your vehicle passes the sound test with a 94.0 dB or lower you will be issued a sound compliance sticker that shows that your vehicle has passed the noise requirement and is OK to run.
Why a 94.0 dB?
Doubling of sound pressure adds 3dB. For example: Two cars producing a 94.0 dB in the same place, at the same time, produce an overall sound emission of a (94 dB + 94 dB= 97 dB). Three cars produce a 99.5 dB and 4 cars would produce 100 dB. The 94.0 dB prevents the  TRACK sound meter limit being reached
What if I passed the 94.0 dB and then I changed my muffler system?
If your vehicle has drastically increased in noise from the approved 94 dB and it produces over a certain sound limit, you could cause the event to be shut down and render monetary fines for the organizer.
Is it possible that my vehicle could produce over the 94.0 dB at the event?
Yes. Each day atmospheric conditions change, this has an effect on vehicle sound emission. This will be taken into account on the day of the event.
What if my car is too noisy at an event and what are the consequences?
This car will be flagged off and not allowed to run.
Can I come to an event and run even if I don’t have my sound compliance sticker?
No vehicle will be allowed to run at AMP without a 94 dB sound compliance sticker. It will be at the event organizer’s option to test vehicles without stickers before the start of the day’s activities.
Is there an overall noise limit for the AMP facility?
Yes. The overall limit is a 99.0 dB for the track and a 92.0 dB on the driving pad. If these sound limits are exceeded 3 times during an event the event will be shut down and the event organizer will pay a fine for each exceedance.
Don’t the noisy jets from Luke AFB blow the AMP sound meter limit?
Yes they do however, AMP has data recording sound meters placed on the site that indicate if loud noises are from a jet or a car on the track.
Why is the event organizer allowed only 3 sound meter exceedances?
If AMP exceeds the overall noise limit for the facility 11 times in any 30 day period, a violation will occur with Maricopa County. This results in a substantial fine and the facility must shut down for thirty days. Allowing only 3 exceedances ensures that AMP will be operational for the next organizer that is scheduled to use the facility.
How does the event organizer pay for the use of the facility?
The event organizer will make a donation to an AMP selected charity for the use of the facility.
How many people can be allowed on site at any given time?

What is the organizer obligated to do?
The event organizer must hire Medical and Safety/Rescue personnel, hire an off-duty police officer if one is required and provide all workers and flaggers.
