The present document provides a review of existing test methodologies to assess speech intelligibility@ quality and listening effort. It should be noted that most test methods (for quality or intelligibility) have been developed with normal hearing people and that there is a lack of data for hearing impaired people. Some clauses of the present document provide a review of existing methods or test results that take into account couplings between phones and listener's ears (acoustical coupling)@ and coupling between phones and hearing aids (inductive@ acoustical or via radio links). Different hearing impairments affecting the listening performance are also considered.
