Volume, also known as loudness and sound intensity, refers to the subjective feeling of the human ear on the intensity of the sound heard, and its objective evaluation scale is the amplitude of the sound. This feeling comes from the pressure produced by the vibration of the object, that is, the sound pressure. The vibration of an object conducts its vibration energy through different media. In order to quantify the feeling of sound into a monitorable index, people divide the sound pressure into a "level"-sound pressure level, which objectively represents the strength of sound, and its unit is called "decibel" (dB).
