In-progress updates to ANSI S12.60 Part 1 pertaining to sound isolation

In early 2022, work began to update ANSI/ASA S12.60, Acoustical Performance Criteria, Design Requirements, and Guidelines for Schools, Part 1: Permanent Schools. The current version of this standard is from 2010. When the working group was polled for comments and requested changes for a new version of the standard, concerns regarding how the 2010 version handles building envelope sound isolation requirements were numerous. Ensuing discussions also revealed concerns with interior sound isolation language. The current progress of the working group’s actions regarding modifications to the standard’s sound isolation language will be discussed.
