Extended data:

Acoustics refers to anything related to hearing. But according to the usual usage, one of them refers to the branch of physics about the property, production and spread of sound; The second refers to the quality of buildings suitable for listening to speeches and music clearly.

Sound is produced by the vibration of an object (such as a musical instrument), which propagates through the air to the eardrum, and the eardrum vibrates at the same speed. The pitch of sound depends on the speed at which the object vibrates. When an object vibrates rapidly, it will produce a "treble" and when it vibrates slowly, it will produce a "bass". The vibration speed of an object per second is called the "frequency" of sound.
