High Sounds of the Sea, Over There
If you love the sounds of the sea, and you want to know where — precisely where in the sea — some of those sounds come from and go to, this study may be of interest: “High frequency directionality measurement of ambient noises from breaking waves in the surf zone,” Hsiang-Chih Chan, Chi-Fang Chen, Ruey-Chang […]
