Ndi chitukuko chofulumira cha kusintha kwa mafakitale, anthu apanga gulu latsopano la "mawu a mafakitale" kuwonjezera pa phokoso la chilengedwe. Kuwonekera kwa "phokoso la mafakitale" kumatsimikizira mapazi a chitukuko cha mafakitale. Komabe, mu chitukuko cha "phokoso la mafakitale" , mosakayikira anasiya "chilema" - phokoso, kotero kuti "phokoso" nkhondo yotetezera inayamba.
Pakali pano, wamba phokoso mayamwidwe ndi kuchepetsa phokoso zipangizo pa msika monga poliyesitala CHIKWANGWANI, galasi ubweya, polyurethane thovu, inorganic thovu zitsulo zipangizo, etc. Monga panopa inorganic thovu zitsulo zakuthupi ndi bwino mtengo ntchito ndi ntchito, phokoso ake mabuku kutsekereza ndi kuchepetsa phokoso mphamvu ndi 7-10 nthawi ya polyurethane thovu, galasi ulusi, ndi zisa aluminiyamu. Ikagwiritsidwa ntchito pamasitima othamanga kwambiri ndi mapanelo amabokosi agalimoto, kutsekereza kwamawu kumakhala pafupi ndi 30dB. Malinga ndi mayeso oyesa, mulingo wa kutchinjiriza kwamawu wamba wamba wowonekera ukhoza kuchepetsedwa ndi 5dB, ndipo zida za aluminium thovu zitha kuchepetsedwa ndi 10-20dB.
Ndi chitukuko cha mafakitale a aluminium thovu, chithovu cha aluminiyamu chimagwiritsidwa ntchito m'magawo ochulukirachulukira pakuyamwa kwake kwamphamvu kwambiri komanso kuchepetsa phokoso ndi zinthu zina zofananira, makamaka pazotchinga zamisewu yayikulu, kuchepetsa phokoso lamsewu, kuchepetsa phokoso la ngalande zam'madzi, komanso mpweya wabwino. Makoma osamva mawu a maiwe osambira; zokongoletsera zamkati zamalo osangalatsa; thovu aluminiyamu kutchinjiriza phokoso pansi; kupanga aluminiyamu ya thovu yamagalimoto, magalimoto onyamula anthu ndi ma mufflers agalimoto; kupanga aluminiyamu ya thovu yomanga zomangira zotulutsa mawu, monga ma situdiyo ojambulira, zipinda zojambulira, zipinda zamakonsati, holo zamisonkhano, mabwalo amasewera, ndi zina zambiri.
