Hmm. I can't hear any noise despite having good sound engineering ears, haha. For me, the cause sounds more like the voltage. As another user has already said, this can be heard with a dimmer, for example, if it regulates the voltage to a lamp that should not be dimmable with a conventional dimmer - such as Hue. However, as it is not really clear whether the problem could also be coming from the lamp, I would personally still try to replace the Hue lamp before you have to call an electrician.

There should not be a noise. It could happen if you are using the bulb in a lamp with a built in dimmer. Hue lights can only be used in lamps without dimmers.
