I added sound deading to the front and rear speaker grill. You still hear the sound but closer to my Tesla speaker volume.

have you removed the cap , put the insulation and reinstalled the cap?

I had to pull away some of the front and rear bumper cover to access the speakers. I found a cup that had the same diameter as the speaker grill. Used it to draw a circle on the sound deadening then with scissors cut it out. Used my hand and gloves to rub the sound material over the speaker. Used a heat gun to soften the material.

thank you, is sound deadening material sticky? never used this before

I used 80 mil thick film. It is sticky on one side. You can use any sound deadening to cover the speaker. I ordered this film from Amazon. I painted the bottom black to hide it. You should be able to find black film on Amazon.

This was my thought.. I'm going to try and will see how easy that cap will come off... Got sheet of 3M08840....

I was not able to pull the grill off. Did not want to damage the grill so I covered it.

To be honest, that noise is way too loud when driving in town. I did call GM about that and they told me there's alot of complaint about it. Today they received a notice that they are actually working on finding à solution for it and that we all can expect something soon. Maybe a recall or an update to fix this issue.

This was the right way to fix it. Thank you for contacting GM for us. The pedestrian protection is important especially for blind walkers in the city and should be simple for GM to lower the volume to the legal requirement.

when I am in a drive thru it is simple to put the Blazer ev into park and back to drive so it did not bother me too much. Way easier than my 2019 Volt was.

The sound level is going to be a pretty low priority on GM's list if GM ever changes it at all. IMO cover it and you will love the car that much more. I never think about the sound level anymore but you do still hear it outside the car. Not disabled but adjusted.

Industry standardizing on a sound would be a good idea. Stop these crazy sounds and switch to recognized sound like an engine. Now what exhaust sound do you get? That will be a debated topic.

@MYSS I used 3M08840 and cut it to fit the speaker.. Used 2 layers. Thank you for your informative post on how to accomplish this. Was very easy to do, only had to remove about 6-7 screws from right front underpan..Do not hear it in the car anymore, but outside it is audible..
Did not do the rear.. Not sure if I going to or not.. Doesn't bother me mearly as much as the front one did..

Thank you!

Link to Napa for the sheet of insulation for anyone interested...

The grill is not only snapped on, it's glued on as well.. Definate no go on removing without breaking it...

Thanks for the link and steps. This is by far the best option. Took me about 15min. You don't need to remove completely the protective panel. I took out about 10 screws to bend it a bit and have access to the speaker. The deadening material sticks really well and now we hear absolutely nothing inside the cabin. Of course if you compare an EV to a Camaro 1968 it makes very little sound. But when comparing to current gas cars, the BlazerEV is a lot more noisy than any brand new gas cars. But having the reverse speaker is a great idea and should also be in gas cars.

Thank you so much mamoMsports!! I have a equinox ev and it's identical as the blazer ev set up. Couldnt find any info on equinox. On the 2 bolt euvs I had u could just pull a fuse (there waz only the pfaf on 1 fuse). I really hate that noise and I honestly don't think it makes any difference, except sounding really weird and getting strange looks from people. At low speeds there is not much difference between newer ICE vehicles and evs

Everyone on this forum should call the EV Concierge line (1-833-382-4389) to complain about the noise!

It's better than the "demonic angel choir" noise the Toyota hybrids make. Teslas sound like UFOs. I think it would be neat if GM allowed customizing the sound by letting us pick from a list.

As I suggested in a similar previous thread on this topic: You run the risk of liability if you have a incident and it is determined that you have modified this system and its reduced effectiveness is determined to have contributed to the outcome. Just food for thought!

I have a new Chevy Blazer EV and this sound is very annoying especially when I pull into my garage and it is still in drive.
This is a federal regulation It's the law: Electric cars must make noise after September 2019 .
Liability is the thing on my mind if I tinker with the fuses and disable it. I will be very worried if I hit someone in the neighborhood, especially a kid, and the blame goes on tinkering with the car to disable it. Society must be able to adapt to a new technology without these federal regulations. I bought it because it is supposed to be quit.

Have had car for just over a week and this is the most annoying thing. Love the car. Got to dial down the volume. So, do I try to fix or hope Chevy does? Any pictures of panel that needs to be removed?

 

[Mattev]

See further up in the thread. There are some pretty good instructions I used. You will see openings in the bottom panels where the front and rear speakers are. Once you have them off you push in on one side of the plug and pull the tab on the other. No more awful sound. Btw chevy will never fix this.

You would think the 'noisemaker' would be variable volume. As loud as it is now at max speed it is required, and when you are driving at a crawl in a parking lot, it would only need to be heard 15-20 feet away, not halfway across the parking lot.
Also, some Japanese ICE cars are basically silent when driving in a parking lot. Why aren't they required to have a 'noisemaker' on them? Are EVs more dangerous?
