Explanation:

• The energy of the vibrating object affects the amplitude of the sound wave. Higher energy means larger amplitude, which is related to louder sound (loudness).
• The condition of the air (e.g., density, temperature) can influence how the sound wave propagates. Different air conditions can change the loudness perception as the wave may lose or gain energy during propagation.
• The distance between the listener and the vibrating source is important. As sound spreads out, the intensity (related to loudness) decreases with distance (inverse - square law \(I=\frac{P}{4\pi r^{2}}\), where \(I\) is intensity, \(P\) is power, and \(r\) is distance).
• The ratio of the wave's frequency to the speed of light is not relevant to sound loudness. Sound is a mechanical wave, and its properties (like loudness) are not related to the speed of light (which is relevant for electromagnetic waves).

Answer:

energy of the vibrating object, condition of the air that the sound wave travels through, distance between you and the vibrating source
