Sound System Simulates the Roar of a Rocket Launch 113

retroworks writes "Located in Noordwijk, Netherlands, and part of ESA's ESTEDC Test Center, is the Large European Acoustic Facility (LEAF), a sound amplification system 'powerful enough to kill a human being.' LEAF is capable of generating more than 154 decibels, the sound equivalent to standing next to several jets taking off. It is used to blast satellites and spacecraft with sound. Large horns are housed in a sound-proofed room that is 16.4meters tall. One wall of horns stands 11 m wide by 9 m deep and 16.4 m high. LEAF requires all the doors to be closed, operating in steel-reinforced concrete walls to contain the noise. The walls are coated with an epoxy resin to reflect noise, producing a uniform sound field within the chamber."

    Day 1: It wouldn't stop, the redirecting. At first I thought it was malware. Had my first drink in a long time.

    Day 2: Barely had the strength to carry on as the BETA REDIRECTIONS continue.. trying not to talk to hallucinations at the bar and in the bathroom which laugh at me about these redirections.

    Day 3: Discovered the BETA redirections were random, and while at first they looked somewhat usable, when I looked at me and my monitor screen in the mirror, a horrible woman with flesh hanging off of her body looked back, trying to lead me into a dance as the word BETA appeared across her rancid breasts.

    Day 4: These BETA corridors go on FOREVER! On the plus side, I've taken up disassembling vehicles to corner this BETA beast and sacrifice myself rather than lead others to discovering it. I ate some red snow.

    Day 5: Finding it harder to concentrate. I've ate some more of the red snow. The taste is starting to grow on me.

    Day 6: This typewriter is the only entertainment I have, apart from throwing things at the walls, trying to get some response from the BETA which is now taking over my mind.

    Day 7: Hahahahahha! Would you believe it? I'M STILL BEING REDIRECTED TO SLASHDOT BETA PAGES! AHAHhahahaah! Type, type, ding, ding! Wooo!

    Day 8: The hallucinations are actually real! Would you believe it? They have offered to help me if I agree to work for them. I'm thinking about patenting this delicious red snow, the taste is unreal!

    Day 9: Having black out sessions where I cannot remember large passings of time. Found some makeup, thought I'd paint a joker smile on my face to amuse the people only I can see!

    Day 10: Productive today, part of what I wrote for my new screenplay:

    I cannot opt out of Slashdot BETA!
    I cannot opt out of Slashdot BETA!
    I cannot opt out of Slashdot BETA!
    I cannot opt out of Slashdot BETA!
    I cannot opt out of Slashdot BETA!
    I cannot opt out of Slashdot BETA!
    I cannot opt out of Slashdot BETA!
    I cannot opt out of Slashdot BETA!
    I cannot opt out of Slas

    You don't die from hearing it, you die from feeling it. So twice as powerful as what it takes to rupture ear drums is in the range of rupturing capillaries in your whole body. Internal bleeding in the brain is a quick killer.
