delay towers/trusses Explanation: Is it related to setting up the audio in an arena? https://books.google.es/books?id=iq_pAwAAQBAJ&pg=PA79&lpg=PA... This is the name given to the towers that are set up at large live events for the diffusion of sound over extended distances away from the stage. P.A. systems (in addition to the P.A.'s present onstage) which grant a virtually uniform sound over very broad surface areas. Due to the distance between the P.A. systems, the sound waves they generate will not be perfectly in phase with the waves coming from the stage. http://www.audiosonica.com/en/course/post/166/Live_sound-Del... -------------------------------------------------- Note added at 1 hr (2015-07-25 18:10:03 GMT) -------------------------------------------------- When you are setting up for a large live sound show it's inevitable to use delay towers. Delay towers help propagate the sound coming out of the P.A. making the concert reach the outer edges of the arena with maximum sound quality. However, there is some math involved when it comes to calculating the delay in sound that a particular delay tower needs. Since sound travels at a specific speed we need to match the sound coming from the delay tower with the sound coming from the stage. Let's look at one of the most practical applications mathematics can help you in your live sound job. http://music.tutsplus.com/tutorials/how-to-calculate-a-delay... -------------------------------------------------- Note added at 1 hr (2015-07-25 18:18:07 GMT) -------------------------------------------------- Here are some photos https://www.google.es/search?q=delay towers&biw=1366&bih=667... |
