through vibrations in the air, that's why you can't hear in space
Sound waves may be generated with very little power at all. A radio running as background sound may have 50mW delivered to the speaker. But the speaker has a very low efficiency - typically of the order of 10% or so. So the amount of sound delivered to the room will be only a few mW.

A radio produces sound, and therefore sound energy. The radio waves, however, are electromagnetic energy, not sound. The function of a radio is to convert that electromagnetic energy into sound energy.
Yes, sound energy is kinetic energy.
To find the energy delivered by each battery, you can multiply the voltage of the battery by the amount of charge it delivers. This will give you the energy in joules.
Electrical Energy Flow
Sound, which is mechanical energy, travels through a solid by setting up a mechanical compression wave in that solid. When the compression wave of the sound in air strikes the solid, it compresses the solid. It isn't much, but the energy delivered by the air is transferred into the solid. Waves of compression and rarefaction move through the solid as they did in air, but move much faster in a solid.
from the sun obviously
Sound energy is produced by vibrating objects, which convert mechanical energy into sound waves. The sound waves travel through a medium, such as air or water, to reach our ears and be perceived as sound.
1. sound energy incident on a panel causes the panel to vibrate (especially at resonant and coincident frequencies). sound energy -> mechanical energy 2. sound energy passing through an absorber will dissipate as heat. sound energy -> thermal energy
Energy is essential for sound production and propagation. When an object vibrates, it creates sound waves which carry energy. The amplitude of the sound wave corresponds to the energy of the vibrations produced by the object. The energy of sound waves determines their loudness and intensity.
