If fundamental principles of sound and vibration control areapplied in the design, installation, and use of HVAC&R systems, suitablelevels of noise and vibration can be achieved with a high probability of useracceptance. This chapter introduces these fundamental principles, includingcharacteristics of sound, basic definitions and terminology, human response tosound, acoustic design goals, and vibration isolation fundamentals. Chapter 48of the 2019 ASHRAE Handbook—HVACApplications and the references at the end of this chapter containtechnical discussions, tables, and design examples helpful to HVAC designers.
