Dr. Litovsky’s research focuses on how people are able to hear in complex, noisy environments, and the contributions of the binaural auditory system (having two ears). The work has several main themes: 1) How we hear speech in noise (the “cocktail party” effect); 2) How we localize sounds; 3) How people with cochlear implants can operate in these conditions, and whether bilateral implants provide benefits beyond unilateral implants. Most of this research takes place at the Waisman Center, where she directs the Binaural Hearing and Speech Lab, working closely with children from the Waisman Center Early Childhood Progarm. She also collaborates with numerous clinics nation-wide that provide cochlear implants to children and adults.
This research is funded primarily by grants from the NIH-NIDCD (R01 DC03083, R01 DC008365, R01DC010494-02).
