Since sound involve sound wave and energy as seen in the above explanation. We can not agree with Geneva given that in order for sounds to be heard, the sound wave produced by a vibrating object needs to travel from the vibrating object to the ear through a medium as a result of radio frequency signals that are leaking into our air causing them to bounce,reflect, enabling them to be heard in the human hearing range.
