We obtain the analytic solutions of the radial part of the masslessKlein-Gordon equation in the spacetime of both three dimensional rotating andfour dimensional canonical acoustic black holes, which are given in terms ofthe confluent Heun functions. From these solutions, we obtain the scalar wavesnear the acoustic horizon. We discuss the analogue Hawking radiation ofmassless scalar particles and the features of the spectrum associated with theradiation emitted by these acoustic black holes.Comment: 20 pages. arXiv admin note: text overlap with arXiv:1405.7846,  arXiv:1501.0046
