Acoustics is the science that studies the generation, propagation, reception and effect of mechanical waves in media. The medium comprises various material states (solid, liquid, gas, etc.), which can be an elastic medium or non-elastic medium. Mechanical wave is the propagation phenomenon of the particle motion changes (including one change or several changes of the displacement, velocity and acceleration). Acoustic wave is a kind of mechanical wave.
Acoustics is a basic discipline of several levels studying linear and nonlinear acoustic wave (mechanical) phenomena in all forms from micro to macro, from infrasonic (long waves) to hypersonic sound (short wave). At the same time, modern acoustics has strong cross and extension, crosses with the majority of modern science and technology subjects, forming a series of model unique interdisciplinary direction, such as medical ultrasound, bioacoustics, ocean acoustics, environmental acoustics, playing a pivotal role in modern science and technology. Modern acoustics is a discipline with the widespread application, plays an extremely important and irreplaceable role in the development of contemporary science and technology, the social and economic progress and the cause of national defense modernization and people's material and spiritual life and improvement.
2. Sound and Communication
Sound is produced by the vibration of an object. The sound propagation needs medium; it can spread in the gas, liquid and solid, but vacuum cannot transmit. Sound transmission in different materials is also different, generally in the spread of the fastest in the solid, liquid second, the slowest spread in the gas. And the velocity of the gas is also related to the temperature and pressure of the gas. A musical sound of music called, no law is the noise sound. Loudness, pitch and timbre are the three factors that determine the characteristics of music.
