Sound transmission refers to the way sound waves travel through different mediums, such as air, water, or solid materials. When an object vibrates, it creates sound waves that move through these mediums by causing particles to oscillate. The speed and quality of sound transmission can vary based on the medium's density and temperature. In general, sound travels fastest in solids, slower in liquids, and slowest in gases. For example, sound travels about four times faster in water than in air. This phenomenon is important in various fields, including acoustics, engineering, and music, as it affects how we perceive and utilize sound.
