ASA Standards is the standards development program of the Acoustical Society of America (ASA). The program develops and publishes voluntary consensus standards in acoustics, mechanical vibration and shock, bioacoustics, animal bioacoustics, and noise.[1]
ASA administers Accredited Standards Committees (ASCs) that develop American National Standards and United States Technical Advisory Groups (US TAGs) for committees of the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC).[2]
History
[edit]ASA members participated in standards development during the early years of the Society.[3]
In 1932, the American Standards Association, a predecessor of the American National Standards Institute (ANSI), appointed ASA as sponsor of the Z24 committee on acoustical terminology and measurements.[3]
Z24 was replaced in 1957 by three standards committees: S1 on Acoustics, S2 on Mechanical Vibration and Shock, and S3 on Bioacoustics. S12 on Noise was established in 1981.[3]
National standards development
[edit]ASA provides the Secretariat for four Accredited Standards Committees and one subcommittee:[4]
- ASC S1 – Acoustics
- ASC S2 – Mechanical Vibration and Shock
- ASC S3 – Bioacoustics
- ASC S3/SC 1 – Animal Bioacoustics
- ASC S12 – Noise
The committees operate under procedures approved by ANSI and based on requirements for openness, balance, due process, and consensus.[4]
Working groups prepare and revise standards for consideration by the applicable consensus body. Standards approved through the consensus process may be submitted to ANSI for approval as American National Standards.[5]
The committees cover subjects including acoustical terminology and measurement, acoustical instrumentation, hearing and bioacoustics, noise measurement and control, mechanical vibration and shock, building acoustics, and animal bioacoustics.[6]
Some ASA standards are incorporated by reference into the Code of Federal Regulations. ANSI's Incorporated by Reference portal lists ASA standards covering subjects including personal noise dosimeters, acoustical calibrators, sound level meters, hearing protectors, hearing aids, and audiometers.[7]
International standardization
[edit]ASA administers US Technical Advisory Groups for ISO and IEC committees in acoustics, mechanical vibration and shock, and electroacoustics.[8]
The ASA-administered US TAGs are associated with:
- ISO/TC 43, Acoustics
- ISO/TC 43/SC 1, Noise
- ISO/TC 43/SC 3, Underwater acoustics
- ISO/TC 108, Mechanical vibration, shock and condition monitoring
- ISO/TC 108/SC 2, Measurement and evaluation of mechanical vibration and shock as applied to machines, vehicles and structures
- ISO/TC 108/SC 5, Condition monitoring and diagnostics of machine systems
- IEC/TC 29, Electroacoustics
US TAGs develop US positions on international standards proposals and ballots and coordinate US participation in the corresponding ISO and IEC committees.[5]
ISO/TC 108/SC 4, Human exposure to mechanical vibration and shock, was disbanded in 2026.[9]
ISO and IEC standards may also be adopted nationally as American National Standards through the applicable standards development process.[5]
Use in government and technical publications
[edit]ASA standards are referenced by government agencies and other organizations in regulations, guidance, and technical publications.
The National Institute for Occupational Safety and Health (NIOSH) includes ANSI/ASA standards in its personal protective equipment standards database, including standards addressing hearing protectors and vibration-reducing gloves.[10]
The Occupational Safety and Health Administration (OSHA) has referenced ANSI/ASA standards in guidance concerning hearing protection, including ANSI/ASA S12.6, Methods for Measuring the Real-Ear Attenuation of Hearing Protectors.[11]
Publications of the National Academies have also referenced ASA-published American National Standards in reports concerning hearing impairment and noise control.[12]
