Auditory Cognitive Neuroscience Experience Lab Room 207 The Laboratory goal is to develop a complete model of how listeners extract information from auditory signals to complete a given task. In order to better understand the workings of the auditory cognitive system, we employ a number of methods including behavioral/perceptual, neuroscience, and computational modeling. The lab’s current major focus is on how listeners adapt their perception to accommodate for variability in the auditory signal (e.g., normal talker variations, foreign accent, Dysarthric speech, spectrally-reduced speech such as that created by cochlear implants, temporally-smeared speech such as that created by bad room acoustics and some hearing aid processing, as well as speech in noise). The ACNE Laboratory consists of a suite of rooms including the lab manager’s office, graduate student offices, common space/meeting room, and a laboratory that is equipped for speech production and general perception experiments. The common space/meeting room is available to all members of the ACNE Lab for small meetings and gatherings. The space includes a conference table, white board, and 32 inch flat screen monitor for presentations.

Lab Room Room 207D The laboratory room has three individual computers with flat-screen monitors and high-end (Sennheiser HD 280 Silver 64Ω stereo) headphones. These individual stations are controlled by a master experimental computer that can manipulate and monitor each station in parallel. Sounds can be presented using high-end computer sound cards or through Tucker-Davis Technology (TDT) Systems II or III. This set up allows for up to three individuals to be run in an experiment at one time. The laboratory also has an AKG C 1000 S Condenser Microphone and a complete Kay Computer Speech Laboratory (Model 4400) for recording and analyzing speech acoustics. Separate workstations are available to ACNE members for digital sound creation/processing, data analysis, and computational modeling. These workstations consist of high-end PCs loaded with MATLAB, SPSS, Adobe Audition, PRAAT, and ALVIN.
