Answer»

Hey friend!
The answer:-

No ,
If the air is removed from the vessel the person STANDING even closely cannot hear the sound .

●REASON ●
Because sound cannot travel through VACUUM it NEEDS a medium to travel. since all the air is removed from the vessel it becomes vacuum inside and hence the person cannot hear the sound of the alarm bell.


hope this HELPS
and if it does PLEASE mark as brainliest☺
