This International Standard specifies a method for measuring the insertion loss of ear-muff type hearing protectors using an acoustic test fixture. The method may be used to investigate production spreads of performance as part of type approval or certification procedures, to investigate the change of performance with age, to ensure that ear-muff hearing protector samples submitted for subjective testing of attenuation according to ISO 4869-1 have performance typical of the type. The method specified in this International Standard shall not be used as the basic test for type approval. Performance data obtained by this method must not 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 earmuffs, the procedure described in this International Standard may have to be slightly modified.
