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 miniature or probe microphones inserted in the
ear canals of human subjects. The measured values are subsequently converted into corresponding free-field 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 microphone-in-real-ear technique (MIRE
technique).
This part of ISO 11904 is applicable to exposure from sources close to the ear, for example during equipment tests
or at the workplace by earphones or hearing protectors with audio communication facilities.
This part of ISO 11904 is applicable in the frequency range from 20 Hz to 16 000 Hz.
