本美国国家标准为声学和电声学中使用的术语提供了定义。许多术语适用于声学的所有分支。还提供了建筑声学、工程声学、物理声学、生理和心理声学、声学和超声波、水声和音乐等领域的一些通用术语。与振动和冲击领域以及心理声学和生物声学领域相关的专门术语包含在通用参考文献中列出的标准中。本标准中提供的定义旨在与国际标准中的相应定义保持一致。本标准早期版本中定义的录音和重放声音领域的术语不在本版本中提供，因为它们更适合作为其他标准的主题。

This American National Standard provides definitions for terms used in acoustics and electroacoustics. Many terms apply to all branches of acoustics. A number of general terms from the fields of architectural acoustics, engineering acoustics, physical acoustics, physiological and psychological acoustics, sonics and ultrasonics, underwater sound, and music are also provided. Specialized terms relating to the field of vibration and shock and to the fields of psychoacoustics and bioacoustics are contained in Standards listed among the general references. Definitions provided in this Standard are intended to be consistent with their counterparts in International Standards. Terms defined in an earlier edition of this Standard for the field of recording and reproducing sound are not provided in this edition because they are more properly a subject for other Standards.
