Dial knob in hotel bathroom

I saw this black dial knob in bathroom of multiple hotel rooms. It is numbered from 0-10.

Any idea what is the use of it?

It seems not a timer. It didn't tick back. Changing it didn't -apparently- change anything.

Best Answer

Usually this controls the volume of an auxiliary speaker placed in the bathroom ceiling, connected to the room’s television. Presumably a number of people continue to listen to their television programmes as they go about their bathroom activities, although the utility of this innovation is rather lost on me.

It appears to do nothing if the television is not on.

The speaker may no longer be connected to anything if the television has been replaced since the hotel was last renovated.
