• NOISE CONTROL in Multi-Family 

    • Learning objectives outline for noise control
    • Two measurements of noise two ASTM standards

    - Sound Transmission Classification (STC) – Airborne Noise

    - Impact Insulation Classification (IIC) – Vibration Noise

    • General ways of improving noise
    • Understanding the ASTM E492 impact  noise
    • Examples – comparison of a 56 vs. a 57
    • Examples – comparison of a 54 vs. a 56
    • Noise control is accomplished in a system, One component isn’t the solution to controlling noise
    • Effects of each component
    • Spring is in the design
    • SPRINGS resilient channels
    • NOISE ANATOMY product effectiveness
    • Ceiling details and flanking
    • Proper isolation of ceiling (drawing/diagram)

    A – Short circuit resilient channels

    B – Resilient channel in contact with wall structure

    C – Gypsum ceiling in contact with wall structure

    D – Gypsum wall in contact with gypsum ceiling

    E – Gypsum wall in contact with subfloor

    • Short circuits in ceiling install  (drawing/diagram)


    An Architect Developer Partnership

    • Things to consider in a new project
    • Other considerations
    • Look to experts
    • Qualities of a good sound mat
    • Mass of gypsum concrete
    • Joist assembly alternatives


    Entangled Net SYSTEMS

    • Systems from 0.25” to 1.75” in thickness
    • Entangled nets are…
    • Selecting the sound mat (budget, midrange, top-of-the-line)


    Entangled Net SYSTEMS – Drawings of Gypsum 

    Concrete and Entangled Net

    • Choosing a fabric: regular or moisture control
    • 4.0-inch Perimeter Isolation


    Learning Objectives

    • Understanding noise and measuring results
    • Idea’s on how to design for quiet living in multi-family
    • The components of entangled net sound systems
