Why would a front-end whirring noise at low speeds happen, wheel bearing?

[JoshuaA]

I’ve got a 2015 Honda Accord that’s started making a faint, high-pitched whirring noise from the front end when I’m coasting at low speeds. It disappears if I touch the brakes or accelerate. I’m worried it might be an early sign of a wheel bearing going bad, but I’ve also heard warped rotors can cause a similar sound.

I had something like that in my old car. It was a faint high-pitched whine when coasting, and it mostly vanished when I touched the brakes. Turned out to be a failing wheel bearing on mine. Replaced and noise gone.

Warped rotors usually give a pulsing feel or a grabbing sensation when you brake, not a whistle while coasting. So that line of thinking might be off here, but I'm not certain.

One time I chased a similar sound and found a loose heat shield by the front wheel; it would rub slightly and vanish under braking. A quick wiggle test finally confirmed it.

Could it be a loose heat shield or something rubbing on the rotor? Those can be quiet most of the time and only show up when coasting.
