In this room, the noise of a rocket taking off is simulated. The large room measures 11 by 9 metres and is 16.4 metres high. One wall is equipped with multiple noise horns, that have a similar design as ordinary speakers. Nitrogen is shot through the horns and can produce noise up to 156 decibels. During tests, no one is allowed into the room that is surrounded by a 0.5-m-thick layer of concrete to keep the noise in. Plato passed its test with flying colours.<\/p>\n<p>[<i>Image description<\/i>: An engineer dressed in a blue lab coat and white hairnet looks upon the Plato\u2019s structural model inside the LEAF chamber in ESA\u2019s ESTEC Test Centre. Plato is put on top of a structure of four wheels. The LEAF room is green and has one wall with huge white holes in the wall. These holes are noise horns that can produce up to 156 decibels. The satellite is surrounded by microphones on sticks to measure the acoustic environment.]<\/p>\n<p>&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\n Click here for original story, <a href=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2023\/06\/Plato_in_ESA_s_LEAF_room\" target=\"_blank\" rel=\"nofollow noopener\">Plato in ESA&#8217;s LEAF room<\/a>&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\nSource: ESA Space Engineering &amp; Technology&#013;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Image: This image shows ESA\u2019s next exoplanet mission, Plato, in the Large European Acoustic Facility (LEAF).
