Saved By Zero - 24 Hours of Electricross
When you take the OHV sound testing program often taught by Dr. Rob Harrison (the godfather of the SAE J1287 “20-inch” sound test for OHVs) he asks the class this question, “If a tree falls in the forest does it make a sound or a noise?”
If you have taken the class you know the answer -- which is -- yes, it makes a sound since sound is a scientific measurement, but not a noise since noise is based on human values or interpretation.
