The vibrations can travel through solids, liquids or gases. The speed of sound depends on the medium through which it is travelling. Sound cannot travel through a vacuum because there are no particles to carry the vibrations. The air is made up of many tiny particles. When sound is created, the air particles vibrate and collide with each other, causing the vibrations to pass between air particles.
The vibrating particles pass the sound through to a person's ear and vibrate the ear drum. Sound is caused by the simple but rapid mechanical vibrations of various elastic bodies.
These when moved or struck so as to vibrate, communicate the same kind of vibrations to the auditory nerve of the ear, and are then appreciated by the mind.
How does the sound travel? Sound vibrations travel in a wave pattern, and we call these vibrations sound waves. Sound waves move by vibrating objects and these objects vibrate other surrounding objects, carrying the sound along. Sound can move through the air, water, or solids, as long as there are particles to bounce off of. Is there sound on the moon? However, the Moon is in space, and space is mostly a vacuum there are always some atoms floating around, but they are VERY far apart and don't interact with one another.
Thus there is no sound on the Moon. Can sound travel through things? Most of the sounds we hear travel through the air, but sound waves can also move through water, wood, and metal. You can test this out for yourself. Everything that you can see has particles that can vibrate.
But if there's no particles, there's nothing to bump into, so sounds can't travel. Does the sun make noise? The surface of the Sun produces sound waves because the surface is convecting and this produces pressure waves that travel into the inner corona.
But yes, the surface does produce sound waves, but they have very low wavelengths measures in hundreds of miles! How fast does sound travel? The speed of sound is the distance travelled per unit time by a sound wave as it propagates through an elastic medium.
What is the human perception of sound intensity? Loudness is the human perception of sound intensity. It is frequently measured in dB which is a scale based on the human threshold of hearing which is given a measurement of 0 dB on up. The dBA scale mimics the human range of hearing by filtering those high and low frequencies people don't hear as well. Why does light travel so fast?
