#1989 BOSE AVIATION HEADSET SERIES#
Product improvements were introduced in 1995 with the Acoustic Noise Cancelling headset Series II, which was awarded “Product of the Year” by the Aircraft Owners and Pilots Association (AOPA). Air Force pilots flying the C-130 6 and other aircraft also have been outfitted with Bose active noise reduction headsets. Army on Abrams Tanks and Bradley Fighting Vehicles. The contract for the Performance Improved Combat Vehicle Crewman (PICVC) headset was renewed and these headsets are used by the U.S.
Air Force selected Bose Corporation to produce an Acoustic Noise Cancelling headset for flight helmets and, in 1993, the Combat Vehicle Crewman (CVC) headset went into production for the U.S. This product was designed for the aviation industry for communication in light aircraft and helicopters. In 1989, Bose Corporation introduced the first commercially available active noise reduction headset. Army and, in 1986, for the experimental Voyager aircraft, in a privately sponsored, non-stop around-the-world flight. Over the next several years, a series of prototypes were built for the U.S. ANR headphones typically use at least one microphone to detect unwanted ambient noise, and the headphone speaker produces sound waves of reverse phase to destructively interfere with the unwanted sound. This technology is known as active noise reduction (“ANR”), also known as active noise control.ĪNR is a technique to reduce unwanted noise by introducing a second sound source that destructively interferes with the unwanted noise. As knowledge increased, Bose engineers began to consider applications for the technology. Bose initiated a research program to work on this problem.Įarly research centered on building models to validate the concept and to allow study of the materials and transducers needed to make the system work. Bose formulated the basic concept and technology for a headphone that would not only reproduce speech and music with high fidelity, but also simultaneously act to significantly reduce unwanted cabin noise. Bose was trying out a 12.new set of airline-supplied headphones and found that the experience was a great disappointment to him, as the fidelity benefits of the new headphones, compared to the older pneumatic tube phones, were masked by significant audible cabin noise and by the distortion that resulted from increasing the headphone volume to overcome this noise. How it all began:During a 1978 flight to Boston returning from Zurich, Dr. patents and applications (22 patents and 14 pending applications). Bose’s current line of noise cancelling headphones, for example, embodies inventions protected by at least 36 U.S. While the legal suit as such may not be much interest to us, we thought the detailed narration of how noise cancelling technology was developed over the last half century, would interest our readers who are increasingly faced with a choice of noise cancelling headphone options:įor almost 50 years, Bose has made significant investment in the velopment, engineering, and design of proprietary technologies now implemented in its products, such as noise cancelling headphones. ANR headphones typically use at least one microphone to detect unwanted ambient noise.” The complaint provides a history of Bose’s work in developing active noise reduction (“ANR”), “a technique to reduce unwanted noise by introducing a second sound source that destructively interferes with the unwanted noise. It claims the patents were issued between 20, and include US Patent 6,717,537 for “Method and Apparatus for Minimizing Latency in Digital Signal Processing Systems” and US Patent 8,345,888 for “Digital High Frequency Phase Compensation.” July 28, 2014: An article in GigaOm last week alerted us to the fact that Audio electronics leaders, Bose has filed a complaint in a US federal court, claiming copyright infringement of its multiple patents in noise cancelling headphone technology, by Apple-owned Beats’ “Studio Wireless” and other brands.
