Take a jar fitted with a single holed stopper and having a sanction pump. Place an electric bell inside.Join it with a battery and switch it on. You hear the bell to ring.Now make vacuum inside by taking out air through the sanction pump.Switch on the bell again.You do not hear it .
Conclusion: Sound needs medium to propagate and hence cannot travel in vacuum.
