CHAPTER 48. NOISE AND VIBRATION CONTROL
tsvibra.irBecause sound travels effectively in the same or opposite direction of airflow, downstream and upstream paths are often equally important. This chapter provides basic sound and vibration principles and data needed by HVAC system designers. Many of the equations associated with sound and vibration control for HVAC may be found in Chapter 8 of the
