For example, the motors used for camera gimbals where the movement is only a few degrees per second.
The subject of noise is seldom mentioned and I've only seen one video where it's clearly demonstrated.
Are slow speed closed loop motors inherently noisy
I cannot answer that accurately. It is highly dependent on the motor type. Brush motors are generally more noisy. Tell us what motors you are concerned about. Closed loop does not make it more noisy.
Making a 2Hz rotating platform for a LIDAR sensor such as the TFmini.
I've seen posts where users of stabilized phone/camera holders sometimes complain about noise problems.
My application is going to be indoors and rotating continuously so any control loop induced noise (like that in the video) is a show stopper.
90% of motor noise is because of poor mounting design that allows a motor to vibrate the mounting system.

Are we talking about electrical noise which I had assumed or are we talking about mechanical noise?
The video is all about acoustic noise.
Sorry I do not watch videos.
