Noise reduction and sound deadening NVH
#16
I finally got around to playing with these settings. Started by turning off the "ESE" (aka the fake engine sounds) and went for a spin. To be honest, I heard absolutely no difference. Next I turned off the ANC and tried again (ESE still off). This time I was able to notice a slight difference, but very slight. The one thing that most stood out to me was I did a full throttle acceleration from stop, the engine did sound a bit more GGggRRRrrrrrr racy especially winding past 5000rpm @ full boost. However when I reached a tad too far over the speed limit I eased up substantially on the gas and heard a (for lack of a better term) wind down noise that I'd never heard before. I know on older cars with turbos when you back off the throttle quickly after coming off of full boost the car will noisily vent the excess pressure to atmosphere but on modern cars it will recycle the air back into the intake. Perhaps this is what I heard and why ANC is apparently only offered on the NX350. I turned the ANC back on for another drive and it did seem to eliminate these noises, but I will continue to experiment to gain more experience with the settings. I'm going to run with the ESE off for a little while to get used to it off, and then turn it back on at some point in the future to see if I can notice any change going back the other way. We'll see. I'm actually still getting used to my NX again, was away for a week on biz in Cincinatti and was driving a Camry hybrid while there. Drove a lot like the Camry Hybrid I once had except Wow, so much more efficient. I used to break out all the hyper mileage techniques to get that car over 40mpg, but this new one was easily getting over 60mpg (indicated anyway). Even when I drove it aggressively, I could not get the tank ave under 57mpg. It also reminded me how firm the NX suspension is in comparison, but while that Camry was generally smoother, it did not track as nice especially on sweeping highway curves. Also sucked having just FWD, annoying
I also took the opportunity to change my lane change flashes to 4, always found 3 not quite enough. Turned on the close and lock walk away function using the kick sensor instead of the button. Could be handy. I also played with the "control engine torque" to smooth out suspension (or words to that effect) but too soon to notice much difference. Maybe if some extra spare time lands in my lap I'll try to record differences with these settings on and off under same conditions to play back and see if there truly is much of a difference or not.
