If you are talking on your phone, and before you hang up, you hear a click sound, and your friend is still on the phone, then someone was eavesdropping on your conversation and hung up.

Yes, sound energy is used when we make noise.
we answer this question by talking which is measured in decibel's and also just use your ear's.
Sound is caused by the vibration of the molecules in a medium. In most cases, this is air, but sometimes can be other materials (screaming underwater, metal on the traintracks). In the tin can phone, the string carries the vibration from one end to the other, where it vibrates the air and becomes normal sound again.
Sound travels through the air in the form of waves, which can reach your ears even if the source of the sound is not within your line of sight. This allows you to hear someone talking even if they are not visible to you.
the funny sound if it sounds like a couple beeps it means someone is calling on the other line
Just don't talk to him on the phone. Or have a secret code between to the two of you.
SOUND
The electrical energy is transformed back into sound waves by the speaker in the phone. These sound waves travel through the air to reach the listener's ear, where they are converted back into sound perception.
-phone means "sound"It has to do with sound or speaking. For example, a "telephone" is something that lets you transmit sound over long distances, while a "francophone" is someone who speaks French.
