This part of ISO 11904 specifies basic framework measurement methods for sound immission from sound
sources placed close to the ear. These measurements are carried out with a manikin, equipped with ear
simulators including microphones. The measured values are subsequently converted into corresponding freefield
or diffuse-field levels. The results are given as free-field related or diffuse-field related equivalent
continuous A-weighted sound pressure levels. The technique is denoted the manikin technique.
This part of ISO 11904 is applicable to exposure to sound from sources close to the ear, for example during
equipment tests or at the workplace to sound from earphones or hearing protectors with audiocommunication
facilities.
This part of ISO 11904 is applicable in the frequency range from 20 Hz to 10 kHz. For frequencies above
10 kHz, ISO 11904-1 can be used.
