1. When sound waves reach our ears, they cause the eardrum to vibrate. These vibrations are transmitted through the middle ear bones to the inner ear, where they are converted into electrical signals. The brain then interprets these signals as sound.

  2. Sound is transmitted through a medium by vibrating molecules. The vibrations cause compressions and rarefactions in the medium, creating pressure waves that propagate outward. These waves travel through solids, liquids, or gases until they reach a listener's ears.

  3. The conservation of energy principle states that energy cannot be created or destroyed, only transformed from one form to another. The total energy in a closed system remains constant, regardless of the processes occurring within the system.

  4. Mechanical energy is utilized to produce sound. Vibrations from a source, such as vocal cords or a musical instrument, convert mechanical energy into sound waves, which travel through a medium and can be heard by a listener.
