It is stressed that criteria should be established in simple basic units and dBA values are recommended. By far the most common single source of annoyance is that of road transportation noise and this aspect has been covered in specific detail. Methods of predicting vehicle noise from the engine design and operating parameters are shown and some measures for noise reduction are discussed.
