What is ocean noise? Animals make noise and hear ours too. Waterways getting busier, noisier. Finding solutions. Focus areas: Fisheries. Topics: ocean. marine mammals. Share: The ocean has always been a noisy place. Many natural sources—like storms, earthquakes, and animals—create underwater sounds.
Ocean Noise. Sound is the most efficient means of communicating underwater, especially for many marine species. NOAA Fisheries works to better understand how marine animals use sound and the potential impacts of man-made noise on the underwater environment.
Natural sounds come from marine life and naturally occurring events like underwater earthquakes. Human-made sounds come from many sources, such as ships, underwater energy exploration, military sonar, and underwater construction, among others. Learn more about sound in the ocean.
Researchers are uncovering just how large the impact of man-made noise is on ocean life. But there are some surprisingly simple ways we could tackle this overlooked pollution problem.
2 Ιουλ 2018 · Scientists now know that as man-made noise travels, it drowns out the natural ocean soundscape and makes it difficult for fish to hear each other.
In the absence of man-made, biological, and transient sounds, ambient noise is wind dependent over the band from below 1 Hz to at least 50 kHz. Below 5-10 Hz, the dominant ambient noise source is the nonlinear interaction of oppositely propagating ocean surface waves.
3 Δεκ 2008 · ROME (Reuters) - Man-made noise in the world's seas and oceans is becoming an increasing threat to whales, dolphins and turtles who use sound to communicate, forage for food and find...
