that first sentence is clearly incorrect.
i have little doubt the LS is quieter than a Model S when at speed however.

The only reasons sounds are a little more amplified in the cabin of my car is... there's no engine noise to contend with! The cabin is isolated from the road so cabin noises are bit more amplified and bounce around with no engine noises to buffer it. I've driven an LS460 and 500, a few S Class, owned several V6 Camrys, and you can always hear the engine no matter how much they isolate it, or use different sound cancelling techniques. Those cars may use better sound dampening materials, but you can't hide the sound of an engine and transmission. The only way to make them quieter... turn the engine off, put them in neutral, and roll them down a steep hill.

BTW @bitkahuna for creating this thread

Driving both an LS and as a passenger in a Model S, the LS definitely uses better sound deadening, so road noise itself is less, but overall the Model S has almost zero drivetrain noise. You can always hear the LS's engine. Because of lots of glass in the model S, sounds inside tend to seem louder than they are, but overall it's quieter because no engine sounds!

Thats actually not true. Sound is not sound, and a sound pressure reading doesn't tell you automatically what your ear perceives as louder. Sound has different frequencies and amplitude, and your ears are more sensitive to some than others regardless of the sound pressure. So, its certainly possible for you to perceive one space as being quieter even though the sound pressure reading is higher.

No engine is an advantage sure.....unless that subjectively sounds worse to someone and that's why it's kinda of useless to be subjective.

Both my wife's Ioniq and my Polestar are so quiet at hwy speeds we had to adjust to it being so quiet. The only reason the Model S may be louder at hwy speeds is because it has 19" and 20" wheels that are lower profile (less sidewall), is not as insulated to road sounds, and lack of engine noise gives a perception that the noise is louder than it really is. For sure the Model S at full WOT is quieter than an LS at full WOT. That said, I'm not taking anything away from the LS, it's an extremely well built competent car that's well insulated from NVH, and the engine is pretty much as quiet as an engine can get

The LS does excellent noise cancelling, the Polestar doesn't do any. In the LS I can still hear the engine, although barely. The Polestar's suspension for sure is louder. I don't know, it's hard to say. Maybe you are right
