2018 Refresh - sound deadening or insulation on back of glovebox
I gave an honest 10 minutes of searching to find a thread I though existed, relating to the 2018 refresh changes. I had not luck...
I wanted to share that yesterday afternoon I changed my cabin air filter and noticed the back of my glove box or glovebox (whatever it's called) has sound insulation. I know many people are always trying to quiet their cabins and this was an interesting find. I would imagine Honda found a significant decibel reduction and decided this was worth the additional costs. This was not on my 2015.
I will add a photo later. Previously I was not thinking this might make a good post so I didn't snap a pic.
edited with picture:
Sorry for not removing the entire box... I had a short lunch break today and didn't have much time to mess with the car. This view is straight in with the box dropped down. 2nd pic is better.
Looking from the passenger door.

Can you post a picture so we can see what type it is?
I have looked back in that cavity and I did not presume that insulation on the glovebox itself would have any effect - because the whole area back there is so much bigger - so if it does that's interesting.

Honda stated that they improved the sound insulation for 2018, but I don't recall that they ever went into any detail as to what they did, other than mentioning switching to a more sound deadening windshield. I know there were complaints about road and wind noise in earlier models but in driving my 2018 around I have no issues at all with noise.
Incidentally. latest Consumers Reports magazine (Dec 2018) is out and they have an article on "Cars You Can Count On" based on latest data. Of the 10 most reliable cars they list, Honda only has one model listed - the Honda Fit. Toyota has 5 vehicles in that top ten list.

I agree, but it covers the entire exposed side and covers it very closely. I wonder if a generic decibel meter on my phone could tell a difference.. Cheap science may investigate this afternoon.

Maybe since it is Friday I can get some time in the garage to see if I can bring more science to this. Currently I am shocked with how easily this decibel measuring app changes it's reading. I don't have a way to know it's calibration, but it seems to be crazy sensitive. This app is called: "Decibel X: dB, dBA Noise Meter"
I ran out in the parking lot to my car and wanted to see what would happen.
I did 20 second averages. Phone held exactly the same way and in the exact same spot, just above the shifter. Air on mixed, vents pointed straight out.
Car off....................................... 54.8dB
Car running................................ 66.5dB 385% more sound pressure than non running
Car running w/blower on full......... 72.5dB 200% more sound pressure than no blower fan
Car running w/blower on full and glove box open as if getting ready to remove the filter... 73.2dB 8% more sound pressure than the blower fan on full
My real world feeling inside the car is that this made zero difference between opening and closing the glove box all the way. The online calculators are saying that it's an 8% increase in noise pressure when I expose the blower motor unit.
To give this any validity, I would need to say I am using something beside an iPhone APP, although the reviews are awesome. Also I am guessing I need to repeat the test maybe 10 times and look for consistency.
Thanks all.

i dont like all the brite work , i did the piece around the shifter when i changed the collar on the boot , have to redo it though , but it still looks better

I had made a DIY on it:
Cabin Air Filter replacement
I took a peek and it doesn't look too hard to fab something in there to replicate the OEM sound dampening.
