? Vibrating air timbre

Analysis: Sound is produced by the vibration of objects; the propagation of sound depends on the medium, gas, liquid, and solid can be used as the medium for propagating sound; the three components of sound The characteristics are: pitch, loudness, and timbre, which describe sounds from different angles. Pitch refers to the level of the sound, which is determined by the vibration frequency; loudness refers to the strength or size of the sound, which is related to the amplitude and distance; timbre is determined by the sound emitter itself. A characteristic that determines.

(3) People can distinguish the sound of "bells" rather than "drums" or other sounds because the timbre is a characteristic determined by the sound body itself; therefore, people distinguish bells and drums based on the different timbres of the sounds. Sound;

So the answer is: (1) vibration; (2) air; (3) timbre.
