Astaamaha ugu muhiimsan ee muraayadaha xumbo aluminium:
1, tignoolajiyada sare, saxan aluminium xumbo isku dhafan, waxqabadka acoustic wanaagsan, xannibaad acoustic ah, miisaan fudud, qurux badan, dab-ilaaliye, aan ka cabsan biyaha, guryaha wanaagsan ee jirka, farsamaynta fudud, oo ka samaysan noocyo kala duwan oo jirka ah oo sanqadha nuugaya, muffler , Qaab dhismeedka dahaarka dhawaaqa, xannibaadda dhawaaqa, qolka muffler, daboolka dhawaaqa, iwm, waxay si toos ah u wajihi karaan isha qaylada, iyada oo aan lahayn wax difaac ah iyo buuxinta kale ee sanqadha nuugaya.
2, Waxay leedahay waxqabadka acoustic aad u fiican: celceliska nuugista codka isku ≥0.60 (125-4000Hz inta jeer); Dhanka kale, waxay leedahay waxqabadka acoustic aad u fiican in waxqabadka nuugista dhawaaqa aanu isbeddelin ka dib marka lagu buufiyo biyaha oo lagu buufiyo dambaska sabuuradda.
3, saxan aluminium xumbo by aluminium aluminium aluminium dhinta-dhimista qaabaynta, jabay, oo dhan dib loo warshadayn karaa, hadda ma aha wasakh sare deegaanka ee alaabta cagaaran-technoolajiyada sare.
