Pastor Matt Posted March 16, 2017 Share Posted March 16, 2017 We hear two sounds from the ocean: "roar" and "crash." Is the roar an accumulation of crashes along the beach, or, is it caused by the air being pushed in front of the waves? Before you answer, consider the roar reportedly heard before a tsunami strikes. Are they the same? Link to comment Share on other sites More sharing options...
dimreepr Posted March 16, 2017 Share Posted March 16, 2017 We hear two sounds from the ocean: "roar" and "crash." Is the roar an accumulation of crashes along the beach, or, is it caused by the air being pushed in front of the waves? http://asa.scitation.org/doi/abs/10.1121/1.1909155 It is concluded that, in general, the ambient noise is a composite of at least three overlapping components: turbulent‐pressure fluctuations effective in the band 1 cps to 100 cps; wind‐dependent noise from bubbles and spray resulting, primarily, from surface agitation, 50 cps to 20 kc; and, in many areas, oceanic traffic, 10 cps to 1000 cps. Before you answer, consider the roar reportedly heard before a tsunami strikes. Are they the same? Probably. Link to comment Share on other sites More sharing options...
Velocity_Boy Posted March 16, 2017 Share Posted March 16, 2017 (edited) We hear two sounds from the ocean: "roar" and "crash." Is the roar an accumulation of crashes along the beach, or, is it caused by the air being pushed in front of the waves? Before you answer, consider the roar reportedly heard before a tsunami strikes. Are they the same? Every sound you ever hear is the result of compressed air waves, that is, groups of air molecules, which very in amplitude and I frequency and thus stimulate tiny, fine hairs in the cochlea of your inner ear... which then in turn create miniscule vibrational waves in your inner ear fluid. Then, finally, the vibrations from those waves are converted to electrical impulses that transmit to your auditory control center in the brain. Which is located in the parietal lobe. The road is the sound being created by the waves as they roll toward the beach. The splash you hear is created by the terminus of the waves collapsing on the solid surface of the sand. Sorry if I got to technical...I'm a Biology nerd. LOL Edited March 16, 2017 by Velocity_Boy Link to comment Share on other sites More sharing options...
