the sound of ringing cellphone decrease on sucking air from tumbler ​because

As there is no medium(air, water) for the sound to travel the sound of the Ringing cellphone gets decreased

Step By Step Explanation :D

What is Sound:

• Sound is a type of energy made by vibrations.
• When any object vibrates, it causes movement in the air particles.
• This movement, called sound waves, keeps going until the particles run out of energy.

How does sound travel:

• sound waves travel at 343 m/s through the air and faster through liquids and solids
• The waves transfer energy from the source of the sound, e.g. a drum, to its surroundings.

What happens when there is no air:

During the propagation of sound, the particles of the medium receive these vibrations and transfer them to the surrounding particles, allowing sound to travel In a vacuum, there are no particles that can transfer and carry vibrations, so sound cannot travel. The most well-known example of a near-vacuum is outer space.
