Model Penjalaran Gelombang Akustik Di Daerah Surface Layer Secara Komputasi

---

In underwater acoustics, one interesting and useful phenomenon in propagatin acoustic signals is the presence of channels in the surface layer. An acoustic wave propagation simulation study has been conducted in the surface layer area. The method was done by applying the Euler-Cromer equation to convert the Snellius equation into an iteration equation. The simulation aims to determine the maximum angle of propagation of acoustic waves. Length of ray and angle variation parameters are used for simulation of acoustic wave propagation. The results of this study showed that the propagation model in the surface layer area at a depth of 0 m-101 m with variations in the length of ray 1 m to 3 m producing a ray emitting distance of 1000 m, 2000 m and 3000 m. Propagation of ray with an initial angle of 0.02 rad and a transmission loss angle of 0.14 rad. From the study, obtained computational data difference values for analytic for the length of 1 m, 2 m and 3 m rays are 1.37%, 1.63% and 4.96% with the range of rays of 664 m, 1328 m and 1992 m respectively. The percentage of error is greater as the length of the ray increases, so the smaller length of the ray the more precise the result obtained even though the wave distance is shorter.
