Noise sensitive volume?

[palincal]

I was driving on a freeway with several long particularly rough patches of pavement. Every time I hit the rough patch my radio volume went up. The volume goes back to normal as soon as the pavement got smooth. I don't remember reading abt noise sensitive or speed sensitive automatic volume control. I guess there was some mention in the demo DVD abt the Bose system doing some active noise cancellation. Am I dreaming? I will try the same freeway again tomorrow.

we do have auto volume adjustment, but I thought it was connected to speed, not noise.

I actually believe it is the noise levels the system picks up. I too have noticed this when noise levels increase inside the cabin.

Hmmm, interesting. The manual talks about "speed sensitive" volume adjustment but nothing about ambient noise.

Depends on what stereo option you have. The non bose 5.1 system has the speed sensitive volume and the bose 5.1 system has the Bose Audio Pilot which senses the interior noise and adjusts volume up to match.

Ahh, yes! That totally makes sense due to the mic the 14 speaker Bose system uses! I was thinking about that too!

I know I have AudioPilot, but I have never been able to hear a difference.

I'm prety sure it doesn't work

Are you seeing it more with radio, DVD, Sat, AUX.

I'd love to get it to work just once so I know I got what i paid for.

[palincal]

I was listening to a CD when I noticed increase in volume. I tried out the same freeway patch again and the volume went up as soon as cabin noise increased. Now I am very sure it works.

[yosM45]

I played a CD today, and drove on some rough roads, and nothing.

I'm sure it doesn't work. It should be this difficult. Pretty upset about this.

has anyone else been able to make it happen?

[striz923]

hate to ask the obvious, but are you sure you have the Bose system? I think that is a key.

[yosM45]

Yes I have the bose system.

i'm sitting here whistling, banging on metal, clapping, yelling, driving on rough roads.

I never hear the volume go up.

I just finished opening the steering column, just to make sure the mic was plugged in properly.

it was.

I'm pretty frustrated. does everyone else hear the volumn change all the time?

When I am driving down the road at 55 mph and I go into the settings and turn off AudioPilot, I hear it get quieter, and louder again when I turn it on. That said, I can't tell when it is changing, but I would think it shouldn't be noticable when it is gradually changing anyway; an old 90's model Impala's compensation would be noticable, but that is because it was based solely on speed and not environmental noise.

I tested my M45 too see if this autopilot thing worked, and i didnt notice any different when driving on the highway...i wonder whats wrong?

[rsg123]

I notice it working occasionally on the freeway when the I go from a newly paved road to a rough one that is due for repair. Make sure AudioPilot is enabled in your settings if you never notice it. The M is a very quiet car so many of you might never notice this feature working. I had a Nissan Armada with this feature and I always noticed it working because it is such a loud vehicle. The tire noise was so pronounced that the volume would increase every time I got up to speed after stopping.

[dvan]

My audiopilot is turned on, looks like im having the same issues as yosm45...

[rsg123]

You guys just need to find a very smooth to very rough highway transition. If the roads are fairly good in your area you might never notice the feature working.I'm kind of puzzled as to your disappointment that you can't notice Audiopilot working...you have a quiet luxury car. You should be happy.

Ive tested it under the conditions you suggest and there is no difference. I'm not disappointed it doesn't work, in fact I would prob turn it off once I noticed it most likely. Plus, if i want to change the volume I have a thumb thats 0.1 inches away from the volume buttons on the wheel! Its just good to know that if you have a feature, it works regardless if you actually use it. I'm quite happy with my M

[yosM45]

I noticed it a couple times since the original post.

I was driving on a very rough not yet paved road. I turned it off and I heard the volume go down.

If it incredibly faint.

[jazzy m45]

I've noticed the feature, but the way that I noticed it the most is when I was at a stoplight and I rolled the windows down. The amount of noise generated by the traffic going across in front of me was enough for the system to automatically raise the volume in the car. The "ambient" noise is what triggered it, so I don't think that clapping, etc., will trigger it. Anyway, the difference in sound is with what I would describe as the "ambient" noise in the music (not your lows and not the voice of the artist, but the actual music).

I've also noticed that there's a difference between having the CenterPoint feature on and off. I've noticed that with the feature on, the system tries to simulate surround sound with everything (radio, CD, whatever), but with it off, it's more like a normal car system (but much better still, of course). With it off though, the normal decrease in bass from the sub as you raise the volume doesn't seem to be as big a drop-off as before. It's a big enough difference for me to switch it off when I want to listen to my music loud and leave it on when I'm just listening to some calm jazz. It has its own advantages and disadvantages. I definitely recommend that you try it different ways to figure out which configuration you want.

I bought a CPO 2012 M37X with the Bose Audio Pilot system, and I can tell you it does not work. Smooth road, rough road, loud tires, come to a stop - the volume never changes.

I had two FX35s before the M, and both had "speed-sensitive" volume controls. Very simple - go faster, it gets louder. Slow down, it gets softer. The M's volume never changes. Seems petty, but it's one of the features that, once you have it, you always want it. Like the back-up sensors, which were not available on the 2012 M. What? Really? On a $65,000 car? I had it in for service recently and asked one of the sales guys to show me how to set the speed-sensitive volume. Sure, he said. He obviously was embarrassed when he realized the car doesn't have that feature!

The car's under warranty, so I'm going to talk to the dealer about the Bose. Maybe my particular system is defective and can be replaced. But from the other posts, it sounds to me like this feature just doesn't work very well - if at all.

Pretty disappointed in these two aspects of the car. Otherwise, it's great. Fast, comfortable, better mileage than the FX, good looking.

Go into settings and then audio if I remember correctly. And it's not based off speed it's ambient sound that the mic picks up. Then again, i don't have 2012.

From 4-17 in the 2012 Infiniti M Owner's Manual:

BOSE® AudioPilot® (if so equipped):
When this item is turned to ON, Audio-Pilot® 2 Noise Compensation Technology monitors noise in the passenger compartment with a microphone and compensates for any unpleasant noise.

Ed Zachly, mate ! It "compenstaes" it does NOT change the volume. Supposedly, it works the way the Bose noise-cancelling headsets work. It emits a noise-cancelling frequency to reduce ambient noise and thereby making the music, etc sound cleaner to be heard better. That said, I have no clue it it really does it or if it's working. When in doubt, turn it up !

[SmoovC]

I think we are talking about two different technologies here.

Speed sensitive volume: the audio system's volume is increased with the vehicle speed. I believe there is a "sensitivity" setting on this?

AudioPilot: as I understand it, the system monitors cabin "noise" with two microphones; one by the sunroof switch, and one towards the rear on the headliner. When "noise" is detected, the system outputs an out of phase audio signal of the same frequency to cancel said noise.

So, as Larz stated; it does act like noise cancelling headphones in that regard.

[TDot]

It is not a noise canceling device or use phase cancelation. It doesn't adjust "volume" either in the simplest form. It adjusts eq based on the ambient noise to compensate for the noise, which is why theoretically you don't hear a tonal difference in the way it all sounds and the base, mids, highs sound relatively the same and why it's perceived to "raise the volume". This is why they market it as they do, because everyone/thing else does actual cancelation...they actually have something that is unque,

... stands corrected. Thanks for that info, mate! That really IS unique for a car system. However I still prefer the Mark Levinson system in the LS460 but that's subjective and varies with each listener's ear holes, LOL.

[TDot]

I still prefer the Mark Levinson system

Shhhhh, don't you dare say that here!! I will have to agree with you whole heatedly and that will start a $#!t storm here lol .

Ban Larz lol

[Larz]

I didn't mention anything about as LS460 and I have no idea how that happened! LOL
I think someone hacked into my Nico account and posted that bit about a Lexus! Thank God they didn't post unseemly pics of my wedding vegetables!

Yes, that is actually more correct, sir.
