ASA - ANSI/ASA S12.42 - AMERICAN NATIONAL STANDARD METHODS FOR THE MEASUREMENT OF INSERTION LOSS OF HEARING PROTECTION DEVICES IN CONTINUOUS OR IMPULSIVE NOISE USING MICROPHONE-IN-REAL-EAR OR ACOUSTIC TEST FIXTURE PROCEDURES Organization: ASA
Date: 2010-01-01
Description: This standard provides methods for the measurement of the insertion loss of hearing protection devices in specified continuous and impulsive noise environments. The microphone-in-real-ear (MIRE) method utilizes human test subjects and may be used for hearing protectors that enclose the ears and make supra-aural or circumaural contact with the head, whereas the acoustical test fixture (ATF) method employs an inanimate fixture and can be used for any hearing protection device.

BSI - BS 6344-2 - INDUSTRIAL HEARING PROTECTORS PART 2: EAR PLUGS Organization: BSI
Date: 1988-09-30
Description: Requirements for materials, construction, assumed protection, sizing and marking and the provision of user instructions for ear plugs, excepting those ear plugs incorporating a semi-rigid interconnection, a communication facility or those in which the acoustic performance is claimed to be dependant upon amplitude.
ASA - ANSI/ASA S12.6 - AMERICAN NATIONAL STANDARD METHODS FOR MEASURING THE REAL-EAR ATTENUATION OF HEARING PROTECTORS Organization: ASA
Date: 2016-06-16
Description: The methods consist of psychophysical tests conducted on groups of human subjects to determine real-ear attenuation at threshold. Two methods are provided, differing in their subject selection, training, hearing protector fitting procedures, and experimenter involvement, but corresponding in all electroacoustic and psychophysical aspects.
DS/EN ISO 4869-3 - ACOUSTICS - HEARING PROTECTORS - PART 3: MEASUREMENT OF INSERTION LOSS OF EAR-MUFF TYPE PROTECTORS USING AN ACOUSTIC TEST FIXTURE Organization: DS
Date: 2007-07-27
Description: Performance data obtained by this method are not intended to be quoted as representing the real-ear sound attenuation of an ear-muff, nor the protection provided by the ear-muff.For the testing of certain ear-muffs (such as those attached to safety helmets, or those with contoured earcups or ear-cushions, or supra-aural ear-muffs), the procedure described in this part of ISO 4869 might need to be modified.
NBN - EN ISO 4869-3 - ACOUSTICS - HEARING PROTECTORS - PART 3: MEASUREMENT OF INSERTION LOSS OF EAR-MUFF TYPE PROTECTORS USING AN ACOUSTIC TEST FIXTURE (ISO 4869-3:2007) Organization: NBN
Date: 2007-10-25
Description: Performance data obtained by this method are not intended to be quoted as representing the real-ear sound attenuation of an ear-muff, nor the protection provided by the ear-muff.
