Ndichitukuko chofulumira cha chitaganya cha anthu, anthu ali ndi zosoŵa zakuthupi ndi zauzimu zochulukirachulukira, ndipo amalondola malo abwino koposa apanyumba. Choncho anthu amagula masitiriyo apamwamba, kuyembekezera kusangalala ndi nyimbo kunyumba; kugula mapurojekitala, kuyembekezera kuonera mafilimu pabedi; kugula treadmills, ndikuyembekeza kuchita masewera olimbitsa thupi osachoka kunyumba. Pamene anthu akusuntha zipangizo zowonjezereka m'nyumba zawo, mosakayikira zimabweretsa vuto lalikulu - phokoso. Choncho, nkhondo yoteteza "phokoso" inayamba.
Pakadali pano, zida zodziwika bwino zoyamwa komanso zochepetsera phokoso pamsika zimaphatikizapo ulusi wa poliyesitala, ubweya wagalasi, thovu la polyurethane, ndi zitsulo zachitsulo. Monga chida chotsika mtengo komanso chosavuta kugwiritsa ntchito cha aluminiyamu cha thovu m'kalasi mwake, mphamvu zake zotsekereza mawu komanso zochepetsera phokoso zimakhala nthawi 7-10 kuposa thovu la polyurethane, ulusi wagalasi, ndi aluminiyamu yachisa. Ikagwiritsidwa ntchito pamasitima othamanga kwambiri ndi mapanelo amagalimoto, 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. Malinga ndi mayeso, zikuwonetsedwa kuti:
| Zakuthupi | Kufotokozera | Chinthu Chochepetsa Phokoso / Kuchuluka kwa Phokoso la Phokoso |
| Polyurethane thovu | 35 mm wandiweyani | Phokoso lochepetsa phokoso ndi 0.85NRC |
| Polyurethane thovu | 35 mm wandiweyani | Kutsekereza mawu ndi 23dB |
| Aluminium thovu zakuthupi | 20 mm wandiweyani | Phokoso lochepetsa phokoso ndi 0.9NRC |
| Aluminium thovu zakuthupi | 20 mm wandiweyani | Kutsekereza mawu ndi 30dB |
Ndi chitukuko cha mafakitale a aluminium thovu, chithovu cha aluminiyamu chimagwiritsidwa ntchito m'madera ambiri chifukwa cha mayamwidwe apamwamba kwambiri a phokoso ndi kuchepetsa phokoso ndi zinthu zina zokhudzana nazo, monga zotchinga phokoso la pamsewu, kuchepetsa phokoso la msewu, kuchepetsa phokoso la sitima zapamadzi, ndi mpweya wodutsa mumsewu; Makoma osamva mawu a maiwe osambira; kukongoletsa mkati mwa malo osangalatsa;foam aluminiyamu phokoso kutchinjiriza pansi; kupanga aluminiyamu ya thovu yamagalimoto, magalimoto onyamula anthu ndi ma mufflers agalimoto; kupanga aluminiyamu ya thovu yopangira zomangira zotulutsa mawu, monga ma situdiyo ojambulira, zipinda zojambulira, malo ochitirako makonsati, maholo amisonkhano, malo ochitira masewera ndi magawo ena, amachita bwino kwambiri.
