Sound needs to travel through something, or you can't hear. Sonce there is nothing in space, sound can't travel.
a police siren!!
All movement causes sound.
Yes! A tree falling in the middle of a large forest still makes a sound, whether or not someone is there to hear it fall.
The sound you hear is just a tone meant to indicate that your call is going through. It is not the same as the one the recipient hears.
Someone who agrees that a sound is made could argue that sound is a physical phenomenon that occurs regardless of human perception. The tree falling creates vibrations in the air which would be interpreted as sound waves if there were an observer present. Someone who disagrees might argue that sound is a subjective experience that requires an observer to perceive it. Without a listener to interpret the vibrations as sound, the falling tree may not technically produce a "sound" in the absence of human perception.
they can hear sound in ears
