    Dimmer switch in the kitchen gave up switching, so I've replaced it. New one hums

    Why? Dodgy switch or what else?

    Previous one was [as near as] silent, not at all noticeable even when right next thing - I never noticed anything. New one, though, audible from several feet away.

    IIRC there are at least 2 types of dimmer switch. One sort hums. The other one whistles. (I may have made the last bit up).

    Your previous dimmer was probably MOSFET or IGBT controlled, which cost more, but are reasonably quiet.
