LS460L: one quiet cabin!
#31
A key measure is idle, and in the data provided that's where the LS 460 runs ahead of the pack. I do think though it depends on the tester, as the LS 430 was tested at 31.1 dB at idle in the front seat by Automotive Marketing Consultants, Inc. in 2002, the quietest on record.
The Toyota Hybrid and Lexus Hybrid are the kings in the "idle" department.

And the LS 600h L is supposedly going to be the quietest sedan in the world, if Lexus is correct! So watch out Prius!
It may also be my bias in wanting to point out where the LS excels. After all, the LS is about 8-10 dB more quiet than the S and 7 at idle; when it goes to the other measures, it is within 2-3, better or worse. At idle, closest is the RR at just 2.8 noiser than the LS. So when you look at the other measures, they are all exceptionally close, but the idle shows that the LS engine/soundproofing is truly quiet indeed, moreso than the S and 7 competition. When the engine is at speed, in the SWB according to Edmunds, it is about the same as the competitors.

got it man, i totally understand your point
although to me i think the running speed db is also very important. very true that wind and some other natural variables around could affect things, but another big factor is suspension setup, which could induce a lot of noise inside the cabin?

I agree, the suspension may be another big factor...maybe even the tires and wheel covers! I'd really like to know at what specific dB range, and what type of footprint the Lexus engineers aimed for when they decided to bring back a bit of the engine noise for the LS 460.
Also I would love to ride in an LS 600h L and compare with the LS 460...and empirically see if the 600h L captures the 'quietest in the world' crown.

Here's a story that proved to me just how quiet this car is. I had a guy I know install paint protection film on the front of our car; when he did the mirrors he remarked that I might get some wrinkles or bubbles since he had to WORK the material to make it conform to the side mirrors. About a day later I noticed a very slight whistling noise. At first I thought it was something I'd just missed, but after thinking about it I realized there was no way the car had been making this noise for the first 500 miles or so; it began the day after I'd had the film installed.
Checked the mirrors and -- sure enough -- the trailing edge of the film had small wrinkles in 2 or 3 spots. Bloody car is so aerodynamically clean -- and incredibly quiet -- that you can hear things that would be obsured in other cars...
