All Audiology Instruments for testing hearing are manufacturerd to a ANSI ( American National Standards Institute) standard for hearing test instruments, There are also standards for spirometry and vision test equipment. Some of the standards are listed below. ** See note below
ANSI S 3.6,1996. rev 2004 for Audiometers.
Applies to all types, including Type 1,2,3and 4.
All related transducers including, earphones,insert phones, bone vibrators and speakers.
ANSI S4.43-1992
For bone vibrators and oscilators.
ANSI S3.1-1991
ANSI S3.1- 1999
For ambient noise levels for hearing test enclosures for diagnostic test facilities.
ANSI S3.39-1987
Aural / acoustic immitance and impedance standard.
Manufactures specifications
for Otoacoustic Emmisions, Autitory Brain Response systems, and Electro diagnostic instruments and accessories.Vision and PFT machines.
OSHA
ANSI S3.6-1969 for Audiometers * see note below
Ambient noise levels for test room enviroments for Hearing conservation programs
**NOTE: Although the audiometers manufactured today may meet the latest standard, most were designed and built to meet the current ANSI Standard at that time of design. Most service providers try to calibrate all equipment to the latest standard, however if it does not, they should then calibrate to the standard as stated by the manufacturer.
*NOTE: Audiometers used in hearing conservation programs are calibrated to the latest ANSI standard (2004)or ANSI 1996, Which exceeds the requirements for OSHA compliance. Bio acoustic simulators ( such as OSCAR and Bio-Betty ) are calibrated to manufactures specifications.
