THE ACOUSTICAL SOCIETY OF AMERICA STANDARDS PROGRAM

1. THE ACOUSTICAL SOCIETY OF AMERICA STANDARDS PROGRAM Paul D. Schomer, Chair ASACOS & Susan Blaeser, Standards Manager Updated Nov. 2007

2. Why Standardize? Some reasons are obvious - • Safety • Assure interoperability of parts • Benefit from “best in class” information • Strive for quality Some are less tangible - • Provide basis for government regulation • Promote product acceptance • Facilitate entry into new markets • Level the competitive field

3. Constituent Organizations of the ASA Standards Secretariat

4. ASACOSAcoustical Society of America Committee on Standards • ASACOS – Policy, finances and program oversight • Representative of each ASA Technical Committee • Chairs & Vice Chairs of Standards Committees • Ex Officio representatives from ASA, TAGs, etc. • Acts on behalf of ASA and makes recommendations to the Executive Council • Executive Committee – Acts for ASACOS when quick action is needed • Chair, Vice-Chair & Standards Manager • Steering Committee – Procedural matters • Executive Committee Members • Chairs of Committees

5. Accredited Standards Committees OperatingUnder ANSI Procedures • S1- Acoustics • S2- Mechanical Vibration and Shock • S3- Bioacoustics • S3/SC 1 Animal Bioacoustics • S12- Noise

6. S1, Acoustics • Acoustical terminology • Sound level meters • Microphones • Acoustical calibrators • Filters • Physical sound measurements • Noise dosimeters • Surface impedance measurement

7. S2, Mechanical Vibration and Shock • Calibration of shock and vibration transducers • Characteristics of resilient mounting • Mechanical vibration of rotating machines • Human exposure to vibration • Balancing

8. S3, Bioacoustics • Hearing aid specifications • Audiometry • Speech interference levels • Articulation index • Threshold of hearing--Audiometric Zero • Calculation of loudness levels

9. S3/SC 1, Animal Bioacoustics NEW • Effects of sound on animals (aquatic and terrestrial) • Instrumentation • Weighting • Terminology

10. Environmental noise measurement and assessment Sound power measurement Hearing conservation Factory noise measurement Noise from ships Liaison Groups (e.g., SAE, ASTM) motor vehicles, aircraft, construction equipment, power tools S12, Noise

11. ISO/IEC Technical Advisory Groups (TAGs)Operating Under ANSI Accredited Procedures • IEC/TC29 Electroacoustics • ISO/TC 43 Acoustics • ISO/TC 43/SC 1 Noise Continued on next slide.

12. ISO/IEC Technical Advisory Groups (TAGs)Operating Under ANSI Accredited Procedures (con’t.) • ISO/TC 108 Mechanical vibration, shock and condition monitoring • SC 2 Measurement and evaluation of mechanical vibration and shock as applied to machines, vehicles and structures • SC 3 Use and calibration of vibration and shock measuring instruments • SC 4 Human exposure to mechanical vibration and shock • SC 5 Condition monitoring and diagnostics of machines • SC 6 Vibration and shock generating systems

13. U.S. Technical Advisory Groups • Organizational members • Chair (vice chair or co-chair) • Provides pool of experts who may participate in ISO/IEC working groups • Establishes U.S. position on ISO/IEC matters more than 80 times per year • For each ISO/IEC ballot a “coordinator” is appointed • Comments solicited from TAG members • Coordinated comments and vote submitted through ANSI (USNC in IEC)

14. ISO Secretariats Administered by ASA • ISO/TC 108 Mechanical vibration, shock and condition monitoring • ISO/TC 108/SC 5 Condition monitoring and diagnostics of machines

15. Primary Documents • ANSI Approved Documents • American National Standards • Nationally Adopted International Standards • Other, e.g., Technical Reports • ISO/IEC Approved Documents • ISO/IEC Standards • Other, e.g., Technical Reports, Technical Specifications

16. Standards Committee & Subcommittee Membership Voting • Organizational Members • Companies • Societies, Trade Assoc. • Government agencies Non-voting • Individual Experts • Working Group Chairs • Working Group Members • Ad hoc Groups • Advisory Groups • Liaison Groups, e.g., SAE, ASTM

17. ANSI Standards Development Process • New Work Effort • Proposal • Ballot Approval • Allocate to existing or new WG • Working Group • Develop Draft Document • Ballot by S-Committee • Try to Reverse Negative Votes or Positions • Adopt • 30-day review • Re-ballot a substantially new document • Public review and comment • Develop Consensus--Much more than a plurality ~90 % • 5-year Review and Reaffirmation

18. ISO Standards Development Process • New Work Effort • Proposal • Ballot Approval-- TAG Vote • Allocate to existing or new WG • Working Group • Working Draft • Develop Committee Draft (CD-1, CD-2, etc.) • Ballot by member bodies to become a Draft International Standard (DIS)--TAG Vote • Committee • Ballot DIS to become Final DIS-- TAG Vote • Ballot FDIS to become a Standard-- TAG Vote • 67% of P-members voting; 75 % of votes • 5-year Review and Reaffirmation

19. Summary • National Standard (ANSI) • Ballot to the S-Committee (or Subcommittee) Members • International Standard (ISO/IEC) • Ballot to the TAG (determines U.S. position) • TAG Members • Liaison Groups • USA Representative • USA Document Coordinator • TAG Chair

20. Result • Impact of National and International Standards • Health and safety – e.g. Speech Interference • Public good – e.g. Classroom Acoustics • Measurement – e.g. Sound Power • Instruments – e.g., Sound Level Meter • Trade
