For a very long time, naval vessels have used sonar technology as a silent, safe tool for mapping and navigating underwater environments in movies and TV shows. However, the reality is quite different. The sound waves emitted by sonar sweeps can have dangerous and even deadly effects on marine wildlife, including humans. In this article, we delve into the terrifying effects of submarine radar on humans, exploring the differences between active and passive sonar, the risks involved, and the potential consequences for those exposed to its powerful soundwaves.
Active vs. Passive Sonar: Understanding the Distinction
There are two types of sonar systems used by marine vessels: active sonar and passive sonar. Passive sonar operates in a listening-only mode, detecting sounds traveling through the water and recording data such as pitch, frequency, and direction. It is commonly used to identify marine life and detect potential enemies in combat situations. On the other hand, active sonar involves the transmission of sound pulses that bounce back to the emitting vessel, providing information about the surrounding environment. Active sonar can be significantly louder, reaching nearly 300 decibels, and poses risks due to its intense soundwaves and detectability.The Risks of Active Sonar: Deafening and Dangerous
Active sonar emits shockwaves that can be incredibly powerful, especially when compared to the vibrations experienced at a loud concert. While concerts may reach around 100 to 120 decibels, active sonar can reach nearly 300 decibels. Exposure to such intense soundwaves could lead to immediate deafness and cause severe internal injuries in humans. In movies, action heroes often survive bomb explosions from a distance, but in reality, the shockwave from an explosion would likely cause severe harm or even death, even if one is not in the epicenter. The effects of sonar shockwaves can be amplified underwater, potentially causing fatal injuries to marine wildlife, such as disorientation and even strandings.The Impact on Marine Wildlife and Environmental Damage
While no human fatalities resulting from sonar exposure have been recorded to date, there have been reports of divers experiencing piercing noises from sonar pings, even from long distances away. However, marine animals are known to suffer the consequences of sonar shockwaves. The intense soundwaves can disorient marine creatures, leading them to swim erratically or panic, often resulting in them beaching themselves or entering dangerous areas. Additionally, shockwaves from active sonar can damage or destroy underwater features, such as rocks and coral reefs.Mitigating the Risks: Sona Usage and Wildlife Conservation
Naval vessels and organizations are aware of the dangers associated with active sonar and take measures to minimize its use. Active sonar is not used continuously due to its potential harm to the underwater environment and its role in revealing the vessel’s location. Instead, passive sonar, which has a lower impact, can be employed for extended periods to detect marine life and monitor enemy activities. By reducing the use of active sonar, the risks to both marine wildlife and humans can be mitigated.Conclusion: Understanding the Harms of Submarine Radar on Humans
Sonar technology, while integral for mapping and navigation underwater, poses significant risks to marine wildlife and human divers when active sonar is deployed. The intensity of the soundwaves generated by active sonar can result in immediate deafness and severe internal injuries in humans. Furthermore, marine animals can experience disorientation, panic, and potential stranding as a result of sonar shockwaves. To minimize these risks, naval vessels employ passive sonar more frequently and limit the use of active sonar. By understanding the dangers associated with submarine radar, we can work towards developing safer and more sustainable practices to protect both marine ecosystems and human divers.
