Silver Member Username: Sw9152Michigan Post Number: 636 Registered: Feb-06 | no i didnt see it. getting louder as you move away doesnt sound right, i dont think sound waves work that way. |

Gold Member Username: Tdeaton1021Near Tampa, Florida USA Post Number: 2917 Registered: Sep-04 | damn, i meant to watch it lol. and its like 155db at a high frequency isnt it? if you had 155db at 2750hz you would wish you didnt have ears... |

Bronze Member Username: LexuscoopPheonix, Arizona USA Post Number: 65 Registered: May-06 | yea, and thats how it works, if you are whiin FEET of the thing, its just an annyoing humm.. but 100 meters away it gets VERY loud, and its maximum distance is 500 meters i believe... and like the X marine was like almost on his knees on the MEDIUM setting at 100 meters away... i didn't think waves worked like that either... but some how the government has changed physics LOL |

Silver Member Username: Sw9152Michigan Post Number: 639 Registered: Feb-06 | what are they using to make the noise? |
|
Bronze Member Username: LexuscoopPheonix, Arizona USA Post Number: 66 Registered: May-06 | they didn't really go into detail... but its liek this BIG WHITE THING lol stands like 7-8 feet tall and is circular |

Gold Member Username: Tdeaton1021Near Tampa, Florida USA Post Number: 2918 Registered: Sep-04 | a 100 inch tweeter with 78mm xmax. i have no idea lol. |
|
Bronze Member Username: LexuscoopPheonix, Arizona USA Post Number: 69 Registered: May-06 | yea.... seems right LOL |
|
Silver Member Username: Sw9152Michigan Post Number: 644 Registered: Feb-06 | or maybe it was just a nextel speaker with and orion 2500d powering it. LOL |

Silver Member Username: GeekbikePost Number: 437 Registered: Dec-04 | Sound works by vibration of particles. If intensity increases based on increased distance, the wave would never dissipate. Everyone on earth would feel the wave and die soon after. |
|
Bronze Member Username: LexuscoopPheonix, Arizona USA Post Number: 73 Registered: May-06 | no they have it based on after 500 meters the waves loose power and disipate |

Bronze Member Username: JcashPost Number: 41 Registered: Dec-05 | they even had little cxars that shoot like machine gunz. And that new device that freezes anyonw within a mile radius something to do with the muscles getting hard and you wont be able to move but you can still hear and see. |

Bronze Member Username: LexuscoopPheonix, Arizona USA Post Number: 74 Registered: May-06 | thats so tight... |

Bronze Member Username: JcashPost Number: 42 Registered: Dec-05 | lol i was joking lmao that would be cool as h3ll though soon enough though the future is full of danger lol. to many crazy sh!t noadays. |

Bronze Member Username: JcashPost Number: 44 Registered: Dec-05 | lol i was joking lmao that would be cool as h3ll though soon enough though the future is full of danger lol. to many crazy sh!t noadays. the little remote cars that shoot are for reals though i seen the preview. |

Silver Member Username: GeekbikePost Number: 438 Registered: Dec-04 | If the video on ROE is the real thing, then it isn't anything special. The intensity doesn't increase based on distance. The frequency is very high, meaning the wavelength is very small. The wave doesn't get more intense as you move further away, it get more intense the more you move towards the direction the wave is moving. You can do the same thing with a tweeter and the same effect will happen. Facing towards you, it will be louder. Facing away or to the side of you, it will not be as loud. |

Gold Member Username: Tdeaton1021Near Tampa, Florida USA Post Number: 2934 Registered: Sep-04 | knacko, your not getting it. fi it wasnt something amazing it wouldnt have cost 40 million and 8 years of research. it consentrates sound waves so well its the same volume 500m away! and 155db at that frequency is just insane in itself. |

Gold Member Username: James1115Ct Post Number: 5806 Registered: Dec-04 | exactly trevor. Knacko if you watch it again he describes how the sound waves are not like those from a conventional loud speaker they are more compact and can be fired with laser pinpoint accuracy that does not allow the sound waves to break up like they do with a loud speaker's pond ripple effect. |

Silver Member Username: GeekbikePost Number: 439 Registered: Dec-04 | The generator they are using is most likely some kind of planar electrostatic speaker. Obviously, it has been carefully refined to the point in the video, but the same concept is already in use in home audio systems. |
