Sboxin Posted September 12, 2017 Share Posted September 12, 2017 Just for clarification - - Where is the Noise limit posted/written for Thunderhill for NASA Nationals West ? I am having difficulty finding this information. And, could someone tell me exactly how they measure the car sound level - distance, location, equipment ? We will be able to comply with the sound level requirements - but it helps to have all the information ahead of time. Thank you, Regards, Link to comment Share on other sites More sharing options...

Thank you, Regards, I believe that there is a sound measurement shack on the right hand side of the car on the main straight after the exit of turn 15, and that the distance may be 50', but to be certain of that plus any further details, contact the track. - Jim Link to comment Share on other sites More sharing options...

We will be able to comply with the sound level requirements - but it helps to have all the information ahead of time. Thank you, Regards, Thanks Jim, I talked with the T-Hill GM and he provided excellent information about their 103 dbA sound level compliance checking - Yes, the testing equipment is 50' on the outside (paddock side) of the turn 15 coming onto the Start/Finish straight - there is a microphone outside and a person inside the booth/shack checking cars for compliance. It is OK to use directional exhaust pipes - HOWEVER, the course flag station workers will also be listening for loud exhaust on the inside of the track and may Black flag a car if they think it does not comply with the 103 dbA level . . . (???) . . . it sounds like T-Hill is serious about the 103 dbA compliance . . . which really isn't too restrictive except for some of us 108 dbA cars - and 5 dbA is a lot of energy reduction . . . We have a muffler to meet a 96 dbA level and will be using that for the NASA Nationals . . . Regards, Link to comment Share on other sites More sharing options...
