Biggest audio hoaxes
I would love to have some kind of noise cancelling system for a listening room. A bit pie in the sky, but people have spent a lot for what seems a lot less plausible. https://www.eevblog.com/forum/chat/sound-cancelling-speakers-in-bedroom-for-traffic/ |
#2 are Bose noise canceling headphones. In this case it’s not that the technolgy doesn’t work, it does, but that the R&D was paid for by you, the US taxpayer, to the tune of over $100 M dollars. Bose received a DoD contract to develop noise canceling technology, and after failing to deliver any usable device or technology the DoD pulled the plug. The $100M written off. ************************************** Bose released their first noise cancelling aviation headset in 1989. They started selling headsets to the military in 1993. Selling them, not starting R&D, but selling. The military started ordering an improved version in 1997. Consumer noise cancelling by Bose was released in 2000. I think we found what the hoax is here. p.s. They employ 9,000 people and have sales of $3.5-4 billion. How much corporate, sales and income tax does that represent? |
