It doesn't sound like that. It sounds like a solenoid or something it being triggered. There are always exactly three knocks, and they are always spaced exactly apart by the same amount of time regardless of engine RPM.

It's quiet enough that if you had the radio on, and/or were already driving fast enough for engine/road noise, you probably wouldn't hear it.

And I just had an oil change within the past month.
