Honorary Academic
In: Psychology » Faculty of Science

Biography

Dr. Kei Kobayashi received his Ph.D (Speech enhancement for hearing loss) from Sophia University after working for 10 years in Sony headquarters Japan. He has a plenty of engineering experience from software/hardware design, project management, to manufacturing for consumer electronics projects such as digital hearing aids, infrared headphones, speakers, integrated remotes and computer OS. At 2005, he moved to NZ and joined in the University as research fellow in audiology, acoustics and currently in psychology (speech and hearing). His research interest is psychoacoustics, speech processing and acoustics. He is especially interested in developing its assistive listening technology / instruments for hearing loss. In his private time, he is supporting well-being for hard of hearing communities in Asia-Pacific countries. He has profound hearing loss since 6 month old and his hearing aid use and engineering expertise allows an appreciation of hearing loss and its challenge to improve quality of life for the community.
