Clause 7 covers the selection, care and use of HPDs. The Standard specifies procedures for estimating the effective A-weighted noise exposure level while wearing HPDs based on laboratory sound attenuation measurements. In addition, a procedure referred to as hearing protector fit testing (HPFT) that evaluates the individual workers’ attenuation using Field Attenuation Estimation Systems (FAES) is also specified.

1.2 Inclusions

The following types of HPDs are covered in this Standard:

a) earplugs;

b) earmuffs; and

c) acoustic helmets.

The sound attenuation testing and reporting requirements set forth in this Standard apply to:

a) general (passive) hearing protection devices;

b) the passive attenuation of electronic HPDs when the electronics are turned off; and

c) amplitude-sensitive (passive level-dependent) HPDs are at low levels. 

Note: Refer to Annex A for a comprehensive description of the different types and features of specialized HPDs.

1.3 Exclusions

This Standard does not address the testing and reporting requirements related to specialized attenuation measurements and/or HPD features such as:

a)    special methods and metrics related to impulsive noise reduction of HPDs (such as the impulsive peak insertion loss (IPIL);
b)    level dependency of sound-restoration (active level-dependent) when the electronics are turned on;

c) level dependency of amplitude-sensitive (passive level-dependent) HPDs at high levels; or
