The noise reminds me of a small plane as it rises higher in the sky. It is only evident while the car is in motion. I do not get an "engine light" signal or any other. This has been happening for several weeks. I keep the maintenance up-to-date. Mileage when this occurred about 100,000. Now at 102,000.
Thank you

    Have a mechanic to telescope your accessories on your engine
