__Materials__ -  A GLX sound measuring reader - A microphone for the beciblles to be picked up with - A jack stand, a clip, and a squaring frame to elevate and hold the microphone in place -  An assortment of cars __Procedure__ - Find a economy, sports, and sedan car from 8 car companies -Find if the vehicle has single or dual exhaust system  -  If the vehicle is a single exhaust system then the GLX will be placed 1.5 feet away from the tail pipe. If it is a dual exhaust then place the GLX in the middle and 1.5 feet back from the car  -  Rev the engine at the following increments as the car allows, idle, 2000 rpm’s, 4000 rpm’s. Record readings for the average rpm level that the GLX noted -  Record findings in a chart and then compare with other findings of that same class of car - Then repeat doing the same procedure but from the middle and 1.5 feet back of the front of the car

=__Notes__=

- Could not do 6000 rpm's and 8000 rpm's because most cars were electric limited at 4000 rpm's. 11-21-09 - Did not follow the procedure for placing the microphone. Instead of placing it in the middle it was placed in front of the tail pipe unless the car and dual then the microphone was placed in the middle of the car. 11-21-09 - Added another test, the front of the car. Same distance and in the middle of the car. This was done for more results and better measurements. 11-21-09 - The Chrystler 300 was ele. limited at 2500 rpms so readings were only recorded at idle 2000 rpms and 2500 rpms 12-29-09 [] [] [|15932595|80551969] [] [] [] [] [] [] http://www.chrysler.com/en/lineup/
