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

 

With acoustic considerations a technically subtle feature 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 comes revisions to ASA’s Classroom Acoustic Standards; specifically:

ASA S12.60 | Acoustical Performance Criteria, Design Requirements, and Guidelines for Schools

ASA S12.60 | Acoustic Standards for Physical Education Teaching Environments

These standards include acoustical performance criteria and design requirements for gymnasia and other physical education learning spaces. Annex A provides procedures for optional testing to determine conformance with the source background noise requirements and the reverberation time requirements of this standard. Annex B provides commentary information on various paragraphs of this standard. Annex C provides guidelines for controlling reverberation in gymnasia and other physical education spaces. Annex D provides guidelines for controlling background noise in gymnasia and other physical education spaces.

Comments are due July 22, 2019

Now comes a revision to ASA’s Standard S12.2 Criteria for Evaluating Room Noise which provides three primary methods for evaluating room noise: a survey method that employs the following:

  • An A-weighted sound level;
  • An engineering method that employs expanded noise criteria (NC) curves;
  • A method for evaluating low-frequency fluctuating noise using room noise criterion (RNC) curves.

Comments are due January 28th.

With acoustic considerations 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

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.  Two documents are of primary interest today.

ANSI/ASA S12.60-2010/Part 1 American National Standard Acoustical Performance Criteria, Design Requirements, and Guidelines for Schools,  Part 1: Permanent Schools.

ANSI/ASA S12.60-2009/Part 2 American National Standard Acoustical Performance Criteria, Design Requirements, and Guidelines for Schools,  Part 2: Relocatable Classroom Factors.

ASA also provides three informative booklets on classroom acoustics:

Classroom Acoustics – A resource for creating learning environments with desirable listening conditions

Classroom Acoustics II – Acoustical Barriers to Learning

Classroom Acoustics for Architects – A companion booklet for ANSI – S12.60

Both of these standards were re-affirmed in 2015 but, the ASA — like all ANSI accredited standards developers — administer technical committees that welcome data and recommendations at any time within the 5-year life cycle of an active standards.   At the moment we find that there are no open ballots.  We encourage stakeholders in the education facility industry to click in to the ASA Open Standards Committee Ballot Page for public commenting opportunities or communicate directly with the ASA standards staff at (631) 390-0215 or asastds@acousticalsociety.org.   

The ASA suite is a standing item on our monthly Arts & Entertainment standards teleconference; the next scheduled for December 18th, 11 AM Eastern time.   You are welcomed to join us with the login credentials at the upper right of our home page.  For an advance agenda, please email bella@standardsmichigan.com
