Question

why does the air is the sound of the bell slow down when sucked through the glass?​

Answer 1

Answer:

No, we don't hear any sound when the bell jar is completely evacuated because all the air is sucked out and there is no medium for the sound to travel inside the jar, which makes it unable to reach the walls of the bell jar so that it can travel through the solid walls of the jar.
