In section 33 of “ My Life as a Bat Atwood has put that “ All i want is to get through the hole in the screen, But that will take some concentration and its hard in this din of voices, they interfere with my sonar. I have found it to be true that bats do use sonar or also known as echolocation. Echolocation is the use of

I Saw You The claim as to whether the eye witness issue on Loch Ness Monster is reasonable and possibly true is worth searching. Loch Ness, placed in the Scottish Highlands, has been that area that a lot of people have sightings of a peculiar creature sneaking in the water. Its long neck and furthermore a snake formed head led individuals to trust it is not an ordinary fish. But instead a massive, complex animal that was eluded to be constantly located to in length ages of time (Val Moffat, eyewitness

selecting mates. Anthropogenic sounds have negative effects on marine life. Humans produce their own underwater sounds through activities such as aircraft overflights, boats and ships (vessels), tourism, stationary offshore activities, air gun firing, sonars, explosions, and methods to control movement of marine life (W. Johnson Richardson and Bernd Würsig, 1997). Many studies have discovered vessels as the main contributor of anthropogenic noise. It is difficult to study the effects of anthropogenic

Abstract Noise is responsible for hidden and or obvious damages. Hearing loss and tinnitus greatly depend on the level of sound (dB) and duration of sound . Short-duration sound of decent intensity primarily a gunshot or explosion will not be described because they are not currently encountered in our normal urban environment. Introduction Noise pollution is a type of pollution that doesn’t get a lot of attention because many people don’t see

sound, arriving at the listener sometime after the direct sound. A true echo is a single reflection of the sound source. The time delay is the extra distance divided by the speed of sound. 2 5 Explain how sonar works and why it is useful. Provide at least one diagram or picture. [5 marks] Sonar is simply making use of an echo. When an animal or machine makes a noise, it sends sound waves into the environment around it. Those waves bounce off nearby objects, and some of them reflect back to the object

fight in the military like humans. Their lives are at the same importance as ours. They should also continue to keep the dolphins and sea lions to help in the Navy because they are the best at what they do. These marine mammals use their biological sonar and penetrating eyesight to detect mines.The biological sonor helps them detect and find the objects around them. This trait makes the animals the best at their job. Dolphins and sea lions should also continue to serve in the Navy because they can

after an assumed maritime clash in the Gulf of Tonkin. Despite the way that the "contention" was very quickly appeared to be the aftereffect of sonar breakdowns, as opposed to genuine Vietnamese hostility, and regardless of the way that the American government displayed the Gulf of Tonkin as proof of Vietnamese animosity long after it thought about the sonar glitches, textbooks keep on listing the Gulf of Tonkin as the most prompt "cause" of America's role in

Is Animal Testing Wrong? It 's on the internet, it 's in magazines, it 's even on the news. Animal testing is a major debate among both academics and everyday people. The most common animals used in testing ae mice, rats, and apes. Some people think that animal testing is obsolete in this day and age but it isn 't obsolete because animal testing helps determine what chemicals are potentially harmful to humans, it helps determine what medicines are potentially safe for human use, and it helps advance

“...Captain McVay had requested a destroyer escort. Despite the Indianapolis having no sonar and despite evidence of Japanese submarine activity in the area, the request was denied. Instead the admirals had simply instructed McVay to adopt a ‘zig-zag’ course” (Pukas, Anna). The zigzag course was to make it harder for sonar equipment to detect the boat (Donohue, Mark), but according to the commander of the Japanese submarines that sunk the Indianapolis,
