There are several possible reasons for the difference in testing results including meter quality and calibration, weather, nearby obstacles, training, and test procedures. The Ranger will be using a Type 1 sound meter, which is the most accurate type of sound meter. The sound meter must be calibrated before use. Also, your sound emissions will change through use and lack of maintenance. Oil can saturate the packing material in the muffler, reducing the sound level absorbing ability. Periodic maintenance is important to retain sound level control qualities.
