Sec 14-80a-1 through 14-80a10a
Should get the PDF file,"Maximum Permissible Noise Standards", on pages 164 to 166 is Section 14-80a-7a Measurements of Noise Emissions, which is the standard the DMV Inspectors should be using for testing , the test site diagram is on page 166. May or may not be a good idea, but depending how the inspection is going, ask the Inspector if they are follwing the standard mentioned above which is Sec 14-80a-1a to 14-80a-10a
The test site diagram, for the 35 mph test, must, I think but not sure, be a side reading as the test should be conducted as the vehicle approaches and drives by. Otherwise, from the rear or front the vehicle would be accelerating, not a constant 35 MPH
For the 35 MPH simulated test where they ask to accelerate the motor, might want to consider not exceeeding a RPM than the equivalent of 35 MPH in high gear. When I was racing the motor to a quick full throttle, really got some extrteme high readings as the RPM far exceeded the equivalent of 35 MPH.
Note: I have had problems copying the DMV link above, might not work. I do not have the software to copy the PDF file.
Car Chemistry and Vortex Cone both mentioned their hardware is most effective as close as possible to the primaries.
GOOD LUCK !!!!!!!
