Okay, okay, all of that stuff is all well and good but does my 2022 Denali have the very cool quiet glass or not? 😁

I don't believe it came till the new body style. It is not that big of a deal.

Most of this went into CUV and SUV models with 4 cylinders. They tried to tame the noise in the cars to be like the V6 and V8 models.

They also used more insulation on some fire walls with noise cancellation.

But then Cadillac pumps in fake engine noise in the audio system because they isolated the engine so much and it is not a V8. No one is happy..

Here this may help........ or hurt. LOL!

How to Tell If You Have an Acoustic Windshield?

Your windshield may or may not be made of acoustic glass. Here is how you can tell and the difference it will make to your driving experience.

My 2023 Buick Envision Avenir has an acoustic windshield it’s stated right in the owners manual if need replaced to be sure it’s an acoustic one. My suv is exceptionally quiet inside and Bose stereo sounds great.

 

[eubie51964]

My next question is do I have acoustic glass in my 2022? I looked in my owner’s manual but I couldn’t find anything. I want some of that very cool quiet glass too! 😂 It’s a lot like some guns I own. One day I don’t know it exists, the next day I can’t live without it!

i think that's every gun i own.

How much is this "Sound and Vibration Package" lol

 

[Bassworship]

From the video supplied with a SUV with the accoustic glass and one without the difference was only 2db. To me that wouldn't make enough difference to even notice.

GMC Customer Care told me the Denali has an "additional sound and vibration package" INCLUDED that is not available on the AT4. Waiting for a reply now for more information and what this actually includes...

 

[Audi403]

From the video supplied with a SUV with the accoustic glass and one without the difference was only 2db. To me that wouldn't make enough difference to even notice.

From what I've read, 2dB is a noticeable difference. dB is a logarithmic scale. An increase of 10dB will appear to sound twice as loud.

For example, 70dB will sound 2x louder than 60dB.

It appears that all models include the acoustic glass, so no worries there.

 

[littleblazer]

For most human hearing... the threshold for a noticeable change in sound is around 2 dB. So it would be "noticeable" technically.

just think about all those people that had wind noise coming from their windshield and had the dealer "fix" it by having another company install a new windshield, my guess is all 3 parties didn't know about this "acoustic glass" so a regular "loud" glass was installed so now its louder in their truck.

 

[Ignitiondoc]

Some things to check: For the side glass, it may be laminated to help with noise. Roll down the window part way and look at the edge. You'll see the three layers with the plastic in the center; For all glass, you may see a notation within the information contained on the label.
Another acoustic technique for side glass is to simply make it thicker, although automakers tend to avoid this as glass is heavy enough already.

 

[Spotman]

I can confirm that the acoustics package is identical for all trim levels except the work truck. The only difference from the WT is the addition a hood and upper plenum insulator. From an acoustic standpoint, the windshields are identical for all trims, including the WT.

just think about all those people that had wind noise coming from their windshield and had the dealer "fix" it by having another company install a new windshield, my guess is all 3 parties didn't know about this "acoustic glass" so a regular "loud" glass was installed so now its louder in their truck.

Well, then they won't hear the wind noise, so problem solved. 😆

For warranty purposes, the dealer is required to get the proper windshield from GM. When we have replaced windshields under warranty, our parts department orders the glass from GM using the VIN, the glass is actually ships to the dealer directly from the glass manufacturer, and we sublet a local installer to do the replacement.
So, if the dealer is following the proper procedures, you should have the correct glass installed.

Very likely. GMC does a terrible job of advertising the specs of these vehicles. Toyota is including acoustic glass on only the premium models of the new Tacoma. It is clearly stated on the build tool.

 

[waterbilly45]

Wahoo! Praise GMC! Using hyperv6’s guidance and link it seems that I do indeed have the coveted acoustic glass windshield and side glass. Thank you, GMC gods for blessing me with silence. Now, the funny part is…. I’m seventy-one years old, been shooting since I was six (under my Dad’s supervision, of course), had many motorcycles, outboard boats, convertibles too, rock concerts, was a jet engine mechanic, operator at a liquid natural gas receiving terminal, operator at a nuclear power plant. Basically I check all off all of the boxes when filling out the paperwork for my hearing test. If I need to shave off a few decibels from my interior cab environment all I really need to do is turn off my hearing aids! 🤣

I reached out to two dealerships to inquire about the differences in cabin noise between the AT4 and the Denali. They both told me the only difference was the tires. I then reached out to GM Canada Customer Care directly, and they gave me a very different answer:

"The GMC Canyon AT4 and Denali trims share the same program architecture, but will have slightly different suspension tuning. The Denali trim has an additional noise and vibration package above the AT4 noise, vibration and harshness standard content that includes acoustic side glass and windshield.

We do suggest that you discuss tire choices with your preferred GMC dealership personnel as tire construction can influence the noise, ride and handling of a vehicle. It is also recommended that above all, you test drive both trim levels to determine which best suits your needs."

This is the first I've heard of the noise and vibration package which includes acoustic side glass and windshield. This is not listed anywhere in the specs on GMs website (that I've noticed). I haven’t heard this mentioned on the forum or any YouTube videos. Why wouldn't GM advertise this if it was a feature included on the Denali package? This would make me lean more towards the Denali trim. Now I'm confused and don't know who to believe.

Has anyone heard of this before?

I would bet there is only one part number for canyon Windshield, regardless of trim. I think it is BS! IMHO.

There is only one part for the front driver/passenger glass and windshield, they are all the same. I checked this after posting.

Waiting to hear back from GM Customer Care to enlighten me on what is actually included in this additional "noise and vibration" package, which is apparently only on the Denali.

I spoke with three dealerships and they all told me the same thing: they've never heard of this before.

 

[Spotman]

There are two different windshield part numbers, one for the HUD equipped trucks and one for all the others. They are essentially the same, but the HUD glass is held to a much tighter tolerance in the HUD zone to prevent distortion of the image.

Yes, but what I meant was that those part numbers are the same between all three trim levels.

 

[Colorado_Steve]

Hmmmm…..I own a Denali and I wonder if the package mentioned has more to do with the Driver Alert system. The Denali will alert you with an audible alarm and vibrate the seat (if enabled) whereas the other Canyon trims do not offer that function.
