I have a 'smart-socket' based B-7971 clock and have the boards set to 'fade' between digits - the noise is super audible - I guess I could/should change it to instant change to reduce the noise but it's only PIR triggered to is mostly off! For bedside clock I have an IN12/IN17 clock from PV Electronics ( https://www.pvelectronics.co.uk/index.php?main_page=product_info&cPath=1&products_id=1) which dims the tubes and colons at night. It works well for me.
