The data presented here was collected for the study described in:
Zobel, B. H., Wagner, A., Sanders, L. D., & Başkent, D. (2019). Spatial release from informational masking declines with age: Evidence from a detection task in a virtual separation paradigm. The Journal of the Acoustical Society of America, 146(1), 548–566. https://doi.org/10.1121/1.5118240
"Twenty-two younger (18-34 years) and 22 older (60-80 years) adults with age-typical hearing completed a yes/no target-detection task with low-pass filtered noise-vocoded speech designed to reduce non-spatial segregation cues and control for hearing loss. Participants detected a target voice among two-talker masking babble while a virtual spatial separation paradigm [Freyman, Helfer, McCall, & Clifton, 1999] was used to isolate informational masking release."
