Because the tube is hollow
You're reed on you're mouthpiece causes the sound that you hear from all woodwind instruments. =)
When you blow across the opening of a bottle, you create a vibrating column of air inside the bottle. This vibrating column of air produces sound waves, which we hear as a tone. The pitch of the sound is determined by the size and shape of the bottle.
When the bow is pulled across the strings, it causes them to vibrate. This in turn causes the air around the strings to vibrate, creating sound. This sound is amplified by resonating inside the violin body, it then travells out of the body loud enough for people to hear.
Blowing at an angle causes air to vibrate against the bottle's edge, creating sound waves inside the bottle. The bottle acts as a resonator, amplifying the sound waves produced by the vibrating air. This results in the audible sound that you hear.
They make the noise from there trunk they just blow and that makes the sound. They also make noises in their body cavities (infra sound) that we can not hear which is propagated through the ground.
All movement causes sound.
You blow a bubble and blow until it cannot go anymore. Hopefully you will hear a snapping sound (I am not exactly sure what you meant by snapping ur gum).
That is the normal sound of the pressure equalizing in the system.
you can hear someone in another room because sound travels. it is like waves that you can hear from a little bit far away. hae hae
Yes, sound is recognized by the brain through your ears. When you hear a sound, it enters the ear canal to the eardrum. The eardrum causes small bones to vibrate, which causes tiny hairs to send signals to the brain.
Blowing into an empty bottle creates sound because the column of air inside the bottle vibrates at a specific frequency. This vibration produces a sound wave that resonates within the bottle, creating the audible sound you hear.
Diffraction is the property of sound that allows you to hear sound waves around corners. It causes sound waves to bend and spread out when encountering obstacles, allowing sound to be heard even when it doesn't travel in a straight line.
