Miyezo yakunja yokweza ma acoustic yomwe idanenedweratu pamagalimoto onyamula katundu wa NASA akuyembekezeka kukhala okwera kwambiri kuposa chilengedwe chomwe chimapangidwa ndi magalimoto oyambitsa malonda masiku ano.
Izi zimapangitsa kuti pakhale kufunikira kokhazikitsa njira yabwino yochepetsera ma acoustic attenuation yamtsogolo ya NASA.
NASA Glenn Research Center idayambitsa zoyeserera zamayimbidwe kuti ziwonetsere kamvekedwe ka thovu la melamine, komanso popanda zowonjezera zosiyanasiyana zamayimbidwe. Kuyesaku kudatchulidwa kuti NEMFAT, yomwe imayimira NESC Enhanced Melamine Foam Acoustic Test, ndipo ndi mutu wa pepalali.
Kuyesa kwa mayamwidwe ndi kutayika kwa kutayika kwa masinthidwe ambiri a thovu kunachitika ku Riverbank Acoustical Laboratory mu Julayi 2013. Deta ya mayeso a NEMFAT imapereka mawonekedwe oyambira acoustic ndi database ya melamine foam ya NASA.
Chifukwa chakuchita kwake kwamayimbidwe komanso kupepuka kofananira ndi mabulangete a fiberglass, thovu la melamine likuganiziridwa kwambiri kuti ligwiritsidwe ntchito pamakina oyimitsa magalimoto amtsogolo a NASA.
