Item Data from: Auditory enhancement under forward masking in normal-hearing and hearing-impaired listeners(2019-11-25) Kreft, Heather A; Oxenham, Andrew J; plumx002@umn.edu; Kreft, Heather A; University of Minnesota Auditory Perception and Cognition LabA target within a spectrally notched masker can be enhanced by a preceding copy of the masker. Enhancement can also increase the effectiveness of the target as a forward masker. Enhancement has been reported in hearing-impaired listeners under simultaneous but not forward masking. However, previous studies of enhancement under forward masking did not fully assess the potential effect of differences in sensation level or spectral resolution between the normal-hearing and hearing-impaired listeners. This study measured enhancement via forward masking in hearing-impaired and age-matched normal-hearing listeners with different spectral notches in the masker, to account for potential differences in frequency selectivity, and with levels equated by adding a background masking noise to equate both sensation level and sound pressure level or by reducing the sound pressure level of the stimuli to equate sensation level.Item Data from: Head and eye movements of normal hearing and hearing impaired participants during three-party conversations(2021-03-04) Lu, Hao; McKinney, Martin F; Zhang, Tao; Oxenham, Andrew J; luxx0489@umn.edu; Lu, Hao; University of Minnesota Auditory Perception and Cognition LaboratoryThe data includes head movement, eye gaze movement and speech segment recorded from 10 young normal-hearing listeners, 10 older normal-hearing listeners and 10 older hearing-impaired listeners during a 3-party group conversation. Each conversation lasts about 25 minutes while different level of background noise were played including no noise, 50 dB, 60 dB and 70 dB SPL noise. The data was released as the supplemental material of the paper [insert paper info] and other researchers working on gaze-guided hearing aids can test their model on it.
