Sound is a vibration of air molecules, at a frequency we can hear. The air is set into vibration by something else that is vibrating; the vocal chords, the violin string, the drum diaphragm, the falling water, the falling tree.
The source of energy for sound waves are vibrations.john vena
That depends, for sound waves typically travel through molecules in the air or really any other median.
Water. Sound is a vibration of molecules, and in air, the molecules are further apart than in water, so the sound wave needs less energy to move each particle away from the source.
The movement of energy through a fluid by the movement of its molecules is known as convection. To observe convection place a heat source by a glass of liquid and observe the changes in temperature inside the liquid from convection.

The source of all sound waves is vibration.
When a wave travels through water, it causes the water molecules to move in a circular motion in the direction of the wave propagation. This circular motion transfers energy from molecule to molecule as the wave passes by, eventually carrying the water molecules along with it. This is how water molecules are transported from the source of the vibration by the wave.
First you have to locate the source of the vibration before you can fix it.

the source of energy causing the wave is vibration.
The purpose of vibration analysis software is to identify the type and possibly the source of vibration. Frequency analysis of a machine's vibration, for example, may lead to the detection of faults.
The effect of soundproofing -- any means of reducing the sound pressure with respect to a given sound source and receptor -- on particles depends on the state of the particles. Soundproofing reflects or absorbs the energy of sound waves that transforms into vibrational energy, thus reduces the vibration and its resultant effects. For particles in the gaseous state, reduced vibration from soundproofing decreases the energy transferred to the free, widely-spaced gas molecules, thus lessening the resultant fluctuation in motion of the gas molecules. As for particles in the liquid and solid state, reduced vibration from soundproofing has a different effect on the particles. In liquids, energy of vibration transferred to the molecules are mostly absorbed by the intermolecular interactions and bonds (e.g., hydrogen bonding between water molecules). In solids, energy of vibration transferred to the molecules are absorbed by the chemical bonds between the particles of the solid. Thus, for both liquids and solids, soundproofing reduces the amount of energy absorbed by the particles.
