I just watched the new Accord review from Throttle House and the new Accord cabin noise and they actually make it quieter. Last gen was 70dB and the new one is around 62 63 dB and i am curious what our Avalon has, i tried to find information but none so far

There was a thread about this before. Like someone mentioned, it would be a meaningless measurement unless it was done with comparable factors, such as the same instrument to measure noise, the same road, same age tires, same wind conditions, etc. And even if it was the same road, it could get repaved later on, invalidating any comparisons to previous measurements, that's what happened to Alex on Autos (see their disclaimer message on top).

Can't help with the numbers, but we just purchased a lightly used 2020 Limited. To the ears, it was noticeably quieter in both wind and road noise than a Cadillac CT5, Toyota Highlander, Nissan Maxima, Genesis G80 and G90, and Kia Telluride. It was not as quiet or smooth as a Cadillac CT6 (no longer in production) but I was concerned about the Cadillac reliability and repair costs. The Avalon gets more road noise at and above 75mph, but overall we are very satisfied. It would have been very cool to test all these with a real instrument, but my tired old ears knew when they were pleased in the cabin.

About a year ago and out of curiosity I downloaded a decibel meter app on my phone and tested my ride at the time, a 2011 Cadillac DTS Premium (this was after I had test driven a 2019 Avalon hybrid and was considering a purchase.) My non scientific test was done on a newly paved stretch of Highway 1 in sunny weather on new Michelin Defender tires at 65 mph. A few days later while taking a second test drive of the 2019 Avalon hybrid I drove the same stretch on the same lane, used the same app, similar time of day/weather, car had a new set of Hankook tires doing 65 mph and discovered that the Avalon was slightly quieter based on my readings. This didn't surprise me as that had been my impression after the first test drive. I ran no other tests using the meter, bought the Avalon, and have since developed the impression that on rougher/older highway pavement the Avalon may be slightly louder than the DTS was. Regardless, I'm very happy with my car, and though I loved my DTS I'd never go back; what an expensive habit THAT was.

Oh, and sorry, I didn't write down the meter readings so can't really say. My bad.

62-63 db?
That"s some concentrated BS. This is Bentley-Rolls territory and these number are untouchable for any mass produced cars.

I"m certain that old Road & Track magazine car tests measured the interior sound level. But, on the web, I found no one posts such a test result (and Road & Track magazine is nearly gone, certainly the current version is nothing like the magazine to which I subscribed for 40 years). I found this at an Autoweek test on the 2019 Limited. I don't recall reading about "noise-reducing glass". Those Honda numbers sound incredibly low, I think they have to be incorrect.

It’s very quiet in here too… with extra sound deadening material in the engine bay and noise-reducing glass

Here are some Rolls Royce and S-Class numbers for reference. There is no way the Honda is in that class.

At a 70mph cruise, the Phantom produces just 60dB of cabin noise, split fairly evenly between distant road noise and gentle wind rustle, with the engine almost inaudible except when it’s called upon to knuckle down. Both the Mulsanne we tested in 2011 and the S350 Bluetec we benchmarked in 2013 produced fully 3dB more (and remember, at that level, half a decibel of extra background hum is enough to be noticeable).

Well you can watch throttle house video, tires and roads make a difference, they test drove the car in California in good developed area so that helps. Also those numbers are just for them to show that the new gen is better than old gen.

I tried using a sound meter app on my phone and the Avalon got 70dB on decent road. Just number so who knows.
