Chotsekera chithovu cha aluminiyamu chotsekedwa chimapangidwa kukhala mbale yogwira bwino kwambiri yotulutsa mawu pambuyo pobowoleza (φ2mm dzenje, chiwongolero cha 1 ~ 3%), chomwe chimakhala ndi mayamwidwe abwino kwambiri, komanso mayamwidwe amawu amatha kufikira 60% ~ 90%. Chifukwa chakuti pamwamba pa zinthuzi mulibe ndege, imakhala ndi ntchito yabwino kwambiri yoyamwitsa mawu, ndipo nthawi yomweyo yatulutsa phokoso la Helmholtz resonance absorber mayamwidwe kuti zitsimikizire kuti mayamwidwe apamwamba amamveka. Kuphatikiza apo, m'malo achinyezi, zida wamba zotulutsa mawu zimatenga chinyezi ndikukulitsa, ndipo mphamvu yotulutsa mawu imachepetsedwa kwambiri, pomwe zinthu za aluminium thovu sizimamwa chinyezi, komanso mayamwidwe ake amamveka samachepetsedwa.
Pamene makulidwe a mpweya akuwonjezeka kuchokera ku 0mm kufika ku 90mm, mafupipafupi a mayamwidwe amawu amachepetsa kuchoka pa 2000Hz kufika pa 300Hz. Pamene makulidwe a mpweya wosanjikiza ndi 10, 30, 60, 90mm, pafupipafupi mayamwidwe amawu ndi pafupifupi 1000Hz, 500Hz, 400Hz, 300Hz motero. Malinga ndi phokoso pafupipafupi kugawa kapangidwe thovu mlingo phokoso mayamwidwe mbale kuseri kwa makulidwe mpweya wosanjikiza. Waukulu pafupipafupi phokoso kwaiye magalimoto mu khwalala, mtsinje pansi mumphangayo ndi ngalande sitima zapamadzi ndi kuzungulira 400Hz, amene ndi otsika pafupipafupi phokoso, kotero mpweya wosanjikiza wa 60mm wandiweyani waikidwa kumbuyo thovu zotayidwa acoustic mbale ya msewu phokoso chotchinga, pansi mtsinje ndi Ngazi yapansi panthaka yamayimbidwe khoma, amene ali wabwino kuchepetsa phokoso zotsatira. Phokoso la njanji ndi phokoso lapakati-pang'onopang'ono pamwamba pa 1000Hz, ndipo 20mm wandiweyani mpweya wosanjikiza umakhala kuseri kwa gulu lotulutsa thovu la aluminiyamu, lomwe limakhala ndi zotsatira zabwino zochepetsera phokoso.
