Hi,
This is almost surely a wheel bearing. Everything you described points towards this and even when in a turn it gets quieter. This is due to loading and unloading the weight of the vehicle on the bearing. When you shift the weight onto the worn bearing it quiets down. So you can drive down the road and swerve back and forth to see which side makes it go away and then that is the side to start with.
Also, if you want to get a recording of this, I can listen to it which will help confirm this because they do make a distinct noise. Thanks
