Abstract
This review provides a summary of the basic theory of scale modeling and some example applications. The article is written to introduce principles and the thinking process unique to scale modeling but not to provide a thorough literature review of relevant articles. Five different examples of scale modeling application to vibro-acoustic problems are given, including architectural acoustics and modeling a concert hall, acoustic streaming jets, acoustic reciprocity, vibration casting, and reduction of NOx by acoustic wave. The scaling laws for the first three examples reported there are introduced in this article based on the law approach, while for the last two examples of scaling laws were developed in this article.
