In 1978, Dr. Amar Bose - sound engineer, MIT professor and founder of Bose Corporation - was flying from USA to Switzerland when he was offered headphones by the airplane staff to listen to music on flight. But, in the constant drone of the airplane engines, and with no way to escape that drone, he could not enjoy the music. In fact, he could barely hear it. He fetched a paper napkin and began scribbling on it with his pen to see if it was possible to design headphones that could remove this noise. The company claims that the mathematical calculations that began in that flight, thousands of feet above the Atlantic Ocean, gave birth to a new era in the science of noise reduction and cancellation. Excited by his early calculations, as soon as Dr Bose returned from his trip to Europe he formed Noise Reduction Technology Group to work on this technology specifically. This, as they say, was history in the making.
