navion Posted July 15, 2008 Report Share Posted July 15, 2008 Ed I was going to ask whether some type of Bose noise cancelling was available. I have Bose noise cancelling headphones (version 2) and if you put them on in the car, ALL noise goes away, its surrealistic, total silence. Why hasn't this innovation been incorporated into the BOSE systems in our cars, are they afraid of potential legal action if someone gets hurt? I think it would be an amazing thing to have That would be cool!! ED is right thats what Acura uses. "The RL Active Noise Cancellation™ system (ANC) can reduce unwanted cabin noise by as much as 10dB, countering it with opposing sound frequencies from the audio system. It uses two microphones located in the ceiling to monitor for low-frequency noise in the cabin. When sound is detected, the ANC control unit passes an inverse waveform to the Bose® amplifier unit, where it is amplified to an inaudible volume that cancels the original sound. To further insulate your cabin from exterior disturbances, the RL's dash, floor, roof, fenders and hood are designed with highly effective noise-insulation materials." There should be a system containing mics and an amp to add to exsiting systems, to obtain the Noise cancellation. New Beechcraft Kingairs have an optional noise reduction system that works the same. I have never experienced it, but I understand that it makes quite a difference. As for the Bose headsets, I was wearing a pair of their aviation noise canceling headsets for the first time. The cancellation feature was turned off, I was flying a Piper Aztec twin and had just pulled the gear up. My friend, who owned the headset, reached over and turned the noise cancellation feature on. It scared the heck out of me! I thought that both engines had quit! It was truly amazing! I actually thought that it worked too good for pilots. A lot of times, you hear a problem before you see it on the gages. This noise cancellation was so good, that it blanked out almost everything except our conversation and the radios. Similarly, too much noise attenuation in a vehicle could be bad. Sirens & horns could be excessively muted. Britt Britt Link to comment Share on other sites More sharing options...
Ed Hall Posted July 15, 2008 Report Share Posted July 15, 2008 Ed I was going to ask whether some type of Bose noise cancelling was available.

Why hasn't this innovation been incorporated into the BOSE systems in our cars, are they afraid of potential legal action if someone gets hurt? I think it would be an amazing thing to have I've thought about this idea for a long time before even before Bose started mass producing their noise canceling headphones to the general public. My 82 diesel Suburban is extremely loud and fatiguing so I started thinking about this idea. But I have yet to see anyone make a system for their own car. So, if I'm driving this noisy beast at night, I'll often use my Bose headset to reduce fatigue from the extreme drone. Anyways, I did a search on the internet and found the following: http://www.digitalworldtokyo.com/index.php..._car_interiors/ http://www.whynot.net/ideas/2981 http://en.wikipedia.org/wiki/Active_noise_control http://techon.nikkeibp.co.jp/english/NEWS_...0080619/153489/ http://www.edmunds.com/insideline/do/News/articleId=104448 http://www.patentstorm.us/patents/5410604/description.html Link to comment Share on other sites More sharing options...
BodybyFisher Posted July 15, 2008 Report Share Posted July 15, 2008 Britt, like you noted, you could hear vocals but low frequency rumble is gone, air noise, road noise etc. Emergency sirens etc, come through just fine. I can't wait till this comes out, and when i get my next car, I am going to try to find an aftermarket solution. I wind the wind and road noise in the car on concrete roads to be annoying. Put my car on smooth tar like roads and its silent, put it on concrete and the noise is transmitted through the car.. THAT is the noise that BOSE gets rid of.. I would be curious to see the Acura system Pre-1995 - DTC codes OBD1 >> 1996 and newer - DTC codes OBD2 >> https://www.obd-codes.com/trouble_codes/gm/obd_codes.htm How to check for codes Caddyinfo How To Technical Archive >> http://www.caddyinfo.com/wordpress/cadillac-how-to-faq/ Cadillac History & Specifications Year by Year http://www.motorera.com/cadillac/index.htm Link to comment Share on other sites More sharing options...

thaghost87 Posted July 17, 2008 Report Share Posted July 17, 2008 One more qualification, it hooks up to my Bose system without a problem... What about that radio you showed me? It had everything except ANC. Then you said you found the steering wheel adaptar to hook up to your system so you can keep your controls. That doesnt sound like a bad option....

Not at all that is a great head unit, for those of us that don't have the Bose system. The only nagging thing that is in the back of my head is that some have said that if you replace the stock radio it creates other problems (codes, etc).

You could try keeping the factory unit in the trunk, i think thats what someone else posted in another post. thats what i might try. Link to comment Share on other sites More sharing options...
Cadillac Jim Posted July 17, 2008 Report Share Posted July 17, 2008 The radio shipped with the car has a computer module that is in the network with the rest of the modules. It has the VIN in it, and the IPM checks all the modules for proper VIN occasionally. If the radio VIN doesn't match, it sets a code and turns off the radio. This is true of all GM cars for some time now and probably most other makes. Anyone who sells and/or installs aftermarket radios will have workarounds. I suspect that all of them for GM cars involve keeping the OEM radio shipped with the car in-place. -- Click Here for CaddyInfo page on "How To" Read Your OBD Codes-- Click Here for my personal page to download my OBD code list as an Excel file, plus other Cadillac data -- See my CaddyInfo car blogs: 2011 CTS-V, 1997 ETC Yes, I was Jims_97_ETC before I changed cars.
