Sound isolation in construction systems separating occupied spaces in all types of buildings is a necessity. This guideline calls for improved acoustical analysis of assemblies, components and installation methods, and a more detailed inspection process beyond the minimum requirements traditionally found in building codes.
ICC G2-2010 provides recommendations such as:
- Two grades of acoustical performance: Acceptable and Preferred performance levels for air-borne and structure borne noise. Both recommendations exceed the current code minimum.
- Specific design and evaluation techniques for managing potential degradation of acoustical performance in sound-rated assemblies caused by flanking paths and sound leaks.
From the Introduction
The principal purpose of the ICC Guideline series is to provide a state-of-the-art volume of knowledge that will contribute to the public health, safety, and general welfare in the built environment Guideline projects are established based on market relevancy, demand, and the realization that existing technical information, regulations, or standards, if any, do not adequately address the subject or that such existing technical information needs to be enhanced clarified and made more user friendly ICC Guidelines are in-depth, topic specific technical publications that have global relevancy and may be used inter nationally. They are different from codes or standards in that they will generally use nonmandatory language.
Development of the ICC Guideline series was approved by the ICC Board of Directors in September of 2008 ICC Policy GP 33-08 governs the development of ICC guidelines and can be viewed on the ICC website at www.iccsafe.org. ICC Guidelines are developed with the establishment of a Guideline Development Committee (GDC). The GDC is made up of a diverse stake- holder population and the participants are focused on ensuring high-quality and timely technical information for the built environment’s usage. Upon the GDC reaching consensus the final draft is posted for a “Public Comment” period for 30 days. The GDC considers all public comments, revises the public comment draft as appropriate and sends its recommendations to ICC for publication. ICC Guidelines are not required to be updated on a specific cycle, however, they will be reviewed periodically and may be updated through a GDC-established process as needed based on changing trends, technology or relevant technical information.
