In this exceedingly short review article, we have provided some information on acoustic topological insulator for pedagogical purpose. Since, intrinsically acoustic systems do not have Kramers doublets due to spin-zero status, artificially acoustic spin-half states could be engineered as reported in refs. 5-26 maintaining time reversal symmetry. The high point of this article is an explanation of emergent Dirac physics in acoustic topological insulators.
