Professor Louis D. Braida is a principal investigator in the Research Laboratory of Electronics (RLE) at the Massachusetts Institute of Technology (MIT). He received the B.E.E from The Cooper Union in 1964, and the S.M. and Ph.D in electrical enginering from MIT in 1965 and 1969 respectively.
Professor Braida is internationally known for his research in the areas of intensity perception, the characterization of hearing impairments, and aids for the deaf. Using modern communication theory and computer-based techniques, he studies auditory behavior transcend sensory levels of traditional psychoacoustics. He has quantitatively analyzed such issues as the functional attributes of short-and long-term auditory memory and its relation to speech reception. Professor Braida has developed a theoretical model that describes auditory and visual cues so that when a speaker’s voice is heard and their face can be seen. This model has applications of intermodal integration: for example, the design can be used to improve hearing aids.
