Lorienne Jenstad, Ph.D., Aud(C) is an Associate Professor at UBC’s School of Audiology and Speech Sciences.  She completed her Ph.D. in Speech and Hearing Sciences at the University of Washington (Seattle). She received her Masters degree in Audiology in 1996 from the University of Western Ontario, where she subsequently worked for four years with Richard Seewald as a research audiologist. Lorienne’s research and teaching areas are amplification, auditory aging and clinical audiology.  Her research is currently funded by an NSERC Discovery Grant and a BC Network for Aging Research Seed Grant.

Research Interests

Hearing aid amplification, with particular focus on the following areas:

1) The effects of amplification signal processing on speech acoustics and speech intelligibility;
2) Determining the acoustic cues used in speech perception by older adults with hearing loss;
3) Determining candidacy for types of signal processing in hearing aids, particularly for older adults.
