Hyundai Ioniq EV Heater Noise

I recently heard an unusual sound while using the heater in my Hyundai Ioniq EV. A buzzing sound is present, and it becomes more noticeable as the fan speed or temperature settings are increased. Is this normal?

It's just the car's heater pump humming along. It's a normal sound, so don't worry about it.
