Sound pioneer Ray Dolby dies at age 80
Ray Dolby, the audio pioneer who founded Dolby Laboratories in 1965, revolutionized film and sound recording in developing the Dolby noise-reduction system, which removed the hiss from analog tape. He also invented digital surround sound, changing how music was listened at home.
After struggling with Alzheimer's disease and being diagnosed with leukemia last summer, Dolby passed away at home Thursday in San Francisco. He was 80.
Dolby Laboratories posted a tribute to its founder, along with a video detailing his contributions to the field of sound.
