We can say that sound energy is just a kinetic energy because sound waves cause the air particles to vibrate which is sensed by our eardrums and thus via sensory nerves they are interpreted by our mind.we also know that energy is neither created nor destroyed.SO WHERE DOES THIS SOUND ENERGY GO?I also read somewhere that this energy is converted into heat energy.but i want to know it is converted into heat energy of what?i guess that they are converted into heat energy of air particles because the particles of air collide each other when sound wave passes through them.correct me if i am wrong.
