BOSTON (AP) — The founder and chairman of the Massachusetts-based audio technology company Bose Corp. has died. Amar Bose was 83.

Bose’s death was announced Friday by company president Bob Maresca and the Massachusetts Institute of Technology, where Bose began his acoustics research and was on the faculty for more than 40 years. The cause of his death hasn’t been released.

Maresca says Bose was an “inspiration to Bose employees around the world.”

The company was founded in 1964. It’s based in the Boston suburb of Framingham and known for making radios and noise-canceling headphones.

Bose in 2011 gave MIT the majority of company stock in the form of non-voting shares whose dividends are used to support education and research. MIT doesn’t participate in management or governance of the company.

Bose was born in Philadelphia to parents from India.
