When a bell vibrates in air, it pushes air molecules out of the way which will make the vibrations "decay". If you strike a bell in vacuum, this loss mechanism will not be there so the bell will "ring" for longer (but nobody can hear it).

✅ No, you cannot hear any sounds in near-empty regions of vaccum. Sound travels through the vibration of atoms and molecules in a medium (such as air or water). In vaccum, where there is no air, sound has no way to travel.
