yes...when we ring the bell in an evacuated bell we are not able to listen the ringing of the bell because there are no air molecules which can collide and produce vibrations.

It is true that,
In vaccum or evacuated system the ringing of bell cannot be heard.
It is so because sound needs a medium to travel which gets removed after evacuation.
