 | | Scientists are focusing on three types of noises: Loud bangs, sonar pings, and explosions that can injure a marine mammal's ears, droning noises from motorboats, and combined noises from commercial shipping that increase the background sound preventing marine animals from communicating. |
 | | Some scientists warn growing levels of human-caused noise in the oceans from military sonar, ships, oil exploration and drilling, offshore construction, motor boats, and jetskis is disrupting and/or killing whales, dolphins, and other marine life. |
