Biggest audio hoaxes

All those scams pale in comparison with by far with the two greatest perpetrated by Bose. #1 is the Bose 901 direct/ reflecting bogosity, all versions.
#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.

Years later, a new engineer happened across the basic research, took on the project anew, and the Bose noise canceling headphones were shortly on the market, based on the original taxpayer funded research. Bose has never reimbursed the government a single dime. Your tax dollars at work. 

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.

**************************************
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?

Not that we got it to work very well, but I have my name on a patent for an outdoor noise cancelling system for road noise.
