Tests to confirm the function and structural strength of spacecraft are conducted in this acoustic test facility in a simulated interior acoustic environment of the launch vehicle fairing during the lift-off and flight stages. Since typical speaker systems cannot achieve required acoustic power, this facility employs an electropneumatic transducer to generate necessary strong acoustic pressure. The test room, called "reverberant chamber," is enclosed by very thick concrete walls. Acoustic field with required spectrum is controlled by feed-back from 4 to 6 microphones deployed in the chamber. While an ordinary loud sound may just annoy your ear, sounds in the chamber are as loud as to damage the test item. | |||
