Ok this is a different noise that I have been hearing.
*** This is different than the high pitch balloon leak that happens during heavy accelleration that's described in this thread http://www.teslamotorsclub.com/showthread.php/9350-The-high-pitched-whine-during-acceleration ***
This sound is tied to the "gas pedal" aka the "go pedal/accelerator". it happens at any speed, slow or fast, from a stop or going 80mph - doesn't make a difference. This sound is constant, but only when pressing down on the accelerator. When you let go of the accelerator, it stops. Push down again, it starts. It's very very easy to hear at slow speeds (<25mph) because tire noise doesn't drown it out. Clearly it's not tied to the high power you'd get under heavy acceleration. This will happen even if your only using 5-10kW power as shown here. It doesn't really get louder if you were doing 30,40,50-100kW etc. It's just a faint whine that you hear constantly as long as your foot is on the accelerator. Ok I've said that like 5 times now. Here is the analysis below.
In the video there are 7 "blocks" where I push down on the accelerator for a second and then let go. I do this over and over (not that I would normally drive like that; I was only doing it to highlight that it is tied to the accelerator). If I were to put the car in cruise control, it would start and be constant the entire time. You can see in the bottom in the spectral frequency display the 7 blocks where I touch the accelerator and then let go. The last 3 are noticeably louder. That is because I was slowing down and there was less tire noise, but I still touched the accelerator for a second at this lower speed to highlight how much more distinct it is when going slower.
Anyone else have this "faint whine" sound that is in sync with pressing down on the MS accelerator? Again, this is *not* the loud balloon leak squeal under heavy acceleration...(I should probably make a capture with both just so ppl can hear the difference....next time )
