the sound of alarm. Now if the air inside the vessel is removed completely how will the loudness of alarm get affected by the same person​

Answer 1

The loudness of the sound will decrease as the air is removed slowly from the plastic bottle. ... The sound cannot travel through vacuum and we cannot hear the sound of the alarm clock at all.
