ISO 11904-1:2002 specifies basic framework measurement methods for sound immissions 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 can be 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).

ISO 11904-1:2002 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.

ISO 11904-1:2002 is applicable in the frequency range from 20 Hz to 16 000 Hz.
