Submarine Sounds

There are many sounds that can be heard on board an operational submarine, some helping it to function within its operational capacity, and others designed to profess transportation in the middle of the crew. For example, submarines use a involved series of sonar sounds in order to navigate under the ocean's waves. This sonar "ping" has become a very recognizable sound from movies and television shows. But how exactly do submarine sounds help a submarine function?
Navigation

Basically, when a submarine slips under the outside of the ocean it becomes blind. At the depths where a submarine travels under the waves, virtually no natural light can penetrate. Because of this, a submarine must rely on several separate things to navigate from one place to another. One of these is sonar.

When a submarine is traveling under water, it can admittedly use sonar to help it orient itself. It does this by bouncing sound waves off of known objects such as rock shelves and underwater formations. By determining the exact position of the submarine relative to these stationary objects, the submarine's operators can consult charts and re-calibrate the exact position of the submarine.

Searching

A submarine also uses active and passive sonar to search other vessels in its immediate vicinity. This is how forces submarines search enemy ships. Active sonar consists of bouncing waves into an area where a vessel is believed to be located. The returning waves will tell the submarine operators the position of the vessel. Passive sonar allows submarine operators to listen for sounds around the sub without actively emitting sonar waves.

Communication

There are many other sounds that submarine sailors will hear besides the classic sonar ping. These include a general alarm, a dive alarm, a outside alarm, a torpedo alarm, an all hands man your battle stations sounding, and a ship's whistle.

Additionally, some submarines have admittedly recorded the audio from forces engagements. while Wwii, the Uss Sealion made recordings or its attack on a Japanese convoy, which resulted in the sinking of the Japanese battle sip Kongo. These historical records contribute anticipated insight into the operational protocol of a submarine while a forces engagement.

Submarine SoundsWEIGHTLESS - Emotional Freediving Tube. Duration : 4.65 Mins.

For full experience it's highly recommended to use headphones or good speakers! Watch also in HD 1080p. Freediving is a sport of diving underwater with just one breath in your lungs. It's about keeping the mind at ease, taking a deep breath and letting your self fall into the ocean. This movie is made to show this sport from a new perspective -- an emotional and mythical view. It's fiction. For a long time we were asking our selves why the internet did not have any videos of freediving as an emotional experience - something like 'Le Grand Bleu' by Luc Besson. Every clip on YouTube had something to do with a stop watch or a long rope. Suddenly Guillaume Nery and Julie Gautier emerged with their film 'Free Fall'. Their film managed to show freediving from a totally new perspective and give the world something never seen before. To us Guillaume Nery and Julie Gautier's 'Free Fall' have started a new short film genre from a freediver's perspective. We wish to contribute to this genre with our film. 'WEIGHTLESS -- Emotional Freediving' is filmed in Dahab, Egypt, January-February 2011 on three different locations. The five hours of footage has been shot solely on breath hold. The deepest filming was done on 20 meters depth and no single clip was longer than 1.5 minutes. We are not world champion freedivers but we love freediving and making movies!
