SAN FRANCISCO – Ray Dolby, who pioneered noise-reducing and surround-sound audio technologies which are fundamental to the music and film industries, has died aged 80, the company which bears his name announced Thursday. Dolby had suffered from Alzheimer's Disease for a number of years, and was diagnosed with acute leukemia last July, it said, adding that the Oscar-winning scientist died at home in San Francisco. "Today we lost a friend, mentor and true visionary," said Kevin Yeaman, President and CEO of Dolby Laboratories, the company which the young Dolby created in 1965.
