Acoustics. Determination of sound immission from sound sources placed close to the ear. - Technique using a microphone in a real ear (MIRE technique) Ingestion-build-137917 BS 7883 gives recommendations for1 Scope 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
