“Visit to the Classroom” | Charles Hunt (1859)

With acoustic considerations a subtle characteristic of effectiveness in many classes of education facilities — classrooms, lecture hall, performance arts and athletic venues, etc.  — we follow action in the Acoustical Society of America (ASA) suite of ANSI-accredited standards.

ASA Standards Homepage

For example, building codes in the United States identify horizontal and vertical acoustic insulation between floors and between walls, respectively, as design considerations.  Section 1206.2 of the International Building Code deal with  horizontal and vertical wall sealant applications for “airborne sound” mitigation, for example.   Fire protection and mass notification systems that depend upon alarms actually being heard by the occupants underscore the importance of acoustic design.

Now come revisions to ASA’s Classroom Acoustic Standards; specifically:

ASA S12.60 Acoustical Performance Criteria, Design Requirements, and Guidelines for Schools, Part 2: Relocatable Classroom Factors.

This commenting opportunity is driven by ANSI’s required 5-year maintenance of this standard which is applicable to relocatable classrooms and other relocatable modular core learning spaces of small to moderate size. Includes siting requirements, acoustical performance criteria, and design requirements for relocatable classrooms. Annex A (informative) provides commentary information on this standard and Annex B (normative) provides procedures for determining compliance with the background sound requirements. Seeks to provide design flexibility without compromising the goal of obtaining adequate speech intelligibility for all students and teachers in classrooms and learning spaces within the scope of this standard.

Comments are due October 14th.

You may obtain an electronic copy from Caryn Mennigke at ASA: (631) 390-0215,  Send your comments to Caryn with a copy to

We are happy to walk through commenting opportunities on any consensus product any day at 11 AM Eastern time.  The ASA suite is also standing item on our monthly Arts & Entertainment Facility standards teleconference.  See our CALENDAR for the day of the next scheduled meeting; open to everyone.
