Theories of sound propagation

Sound propagation theories describe how sound waves travel through different environments. The main idea is that sound originates from a source that creates vibrations which move through a medium such as air, water, or solids. These vibrations produce waves that spread outward, transferring energy. Key theories include the wave theory, which treats sound as a wave with frequency and wavelength, and the particle theory, which considers the medium's molecules oscillating to transmit sound. Factors like temperature, humidity, and obstacles influence how far and fast sound travels. Understanding these theories helps in designing better acoustic devices and environments.
