We’re delighted to announce this week’s set of newly reaffirmed ASA Standards (ready for purchase in our ASA Standards storefront):

S3 Committee (Bioacoustics):

ASA/ANSI S3.13-1987 (R2024)
Mechanical Coupler for Measurement of Bone Vibrators

Abstract:
This standard specifies requirements for mechanical couplers used for calibrating bone-conduction audiometers and making measurements on bone vibrators and bone-conduction hearing aids. Specific design features are given for the mechanical coupler when driven by a vibrator with a prescribed plane circular tip area and applied with a specific static force. An appendix provides an example of a specific construction of a mechanical coupler.

 ASA/ANSI S3.45-2009 (R2024)
Procedures for Testing Basic Vestibular Function

Abstract:
This Standard defines procedures for performing and reporting a battery of tests for the evaluation of human vestibular function. Six different tests are specified. Stimuli are presented to evoke eye movement by a subject whose response is determined either by measurement of electrical signals generated by the eye movements or by image processing methods applied to video eye movements. The Standard specifies test procedures, measurements, data analysis, and data reporting requirements. These tests, including the data analysis and reporting procedures, are called the Basic Vestibular Function Test Battery. Test interpretation is not a part of this Standard.

S12 Committee (Noise):

ASA/ANSI S12.60/Part 1-2010 (R2024)
Performance Criteria, Design Requirements, and Guidelines for Schools – Part 1: Permanent Schools

Abstract:
This document is Part 1 of the ANSI/ASA S12.60 series and is applicable to classrooms and other learning spaces in permanent schools. Part 2 of the ANSI/ASA S12.60 series is applicable to relocatable classrooms and relocatable modular core learning spaces. This standard includes acoustical performance criteria, and design requirements for classrooms and other learning spaces. Annex A provides procedures for optional testing to determine conformance with the source background noise requirements and the noise isolation requirements of this standard. Annex B provides commentary information on various paragraphs of this standard. Annex C provides guidelines for controlling reverberation in classrooms.
