Connection between Ocean Acidification and Sound Propagation

Ocean Ambient Noise (OAN) results from both anthropogenic and natural sources. Varied noise sources are dominant in low (LFB: 10 to 500 Hz), medium (MFB: 500 Hz to 25 kHz) and high (HFB:>25 kHz) frequency bands. Mostly, LFB is dominated by anthropogenic sources. MFB that cannot spread over long r...
