Currently there are many different laboratory-based tests of spatial release from masking (SRM) that use speech materials, however there is still disagreement as to the impacts of age and hearing loss on SRM. It is time, then, to take these tests out of the laboratory and begin testing larger numbers of listeners varying in age and hearing ability in order to provide the statistical power needed to answer the questions currently being asked. Unfortunately, most of the tests that have been developed are either open set, and thus require a tester to administer them, or require complex soundfield speaker arrays. Our laboratory has recently developed and verified an automated headphone-based test that can be presented in only five to ten minutes and that provides results that are predictive of results obtained in an anechoic chamber.
