Automotive tire facility noise characteristics

The environmental noise influence of facilities that change, replace or repair tires has notable acoustic characteristics, including the sound from air impact wrenches. Air impact wrenches are a ubiquitous tool at such facilities, where they are used to remove and replace the nuts that hold wheels on cars and trucks. The sound is commonly emitted through open doorways. Tire facility sound data was evaluated for impulsive characteristics using procedures described in the newest version of ISO 1996-3. The dynamic nature of air impact wrench sound also allowed the ISO 1996-3 approach to be evaluated.
