  • HVAC Systems: Noise and Vibration Control Principles

    Credits: 3 PDH

    PDH Course Description:

    This course examines the engineering principles and practical methods used to identify, analyze, and mitigate noise and vibration in HVAC systems. It provides a technical overview of the sources of sound and mechanical vibration in heating, ventilation, and air conditioning equipment, and introduces proven control strategies including isolation, damping, absorption, and acoustic shielding. 

    The course explores both airborne and structure-borne pathways of sound transmission, the influence of ductwork and support structure design, and how to meet applicable noise control standards in residential, commercial, and industrial applications. Emphasis is placed on engineering design considerations for quiet, efficient, and code-compliant HVAC system installations.

    Topics:

    Upon completion of this course, participants will be able to:

    • Identify the primary sources of noise and vibration in HVAC systems.
    • Distinguish between airborne and structure-borne transmission mechanisms.
    • Understand fundamental acoustic and vibration principles as applied to mechanical systems.
    • Evaluate methods for isolating and reducing vibration at the source.
    • Apply strategies for attenuating duct-borne noise and resonances.
    • Select appropriate materials and mounting configurations to mitigate unwanted system noise.
    • Analyze the impact of equipment placement and building structure on sound propagation.
    • Understand applicable standards and regulations for noise levels in building environments.
