Ngokuthuthuka okusheshayo komphakathi wesintu, abantu banezidingo ezengeziwe zezinto ezibonakalayo nezingokomoya, futhi baphishekela indawo yokugcina yasekhaya enethezekile. Ngakho abantu bathenga ama-stereo asezingeni eliphezulu, benethemba lokujabulela umculo ekhaya; thenga ama-projektha, ngethemba lokubuka amafilimu embhedeni; ukuthenga ama-treadmill, ngethemba lokuzivocavoca ngaphandle kokushiya ikhaya. Njengoba abantu bethuthela izinsiza eziningi ezindlini zabo, nakanjani kudala inkinga enkulu - umsindo. Ngakho, impi yokuzivikela “yomsindo” yaqala.
Njengamanje, izinto ezijwayelekile ezimunca umsindo nezinciphisa umsindo emakethe zifaka i-polyester fiber, uboya bengilazi, igwebu le-polyurethane, nezinto zensimbi eyigwebu. Njengempahla yegwebu ye-aluminium engabizi kakhulu futhi esebenziseka kalula ekilasini layo, amandla ayo okufaka umsindo aphelele kanye nokunciphisa umsindo aphindwe izikhathi ezingu-7-10 kunegwebu le-polyurethane, i-glass fiber, ne-aluminium yezinyosi. Uma isetshenziswa ezitimeleni ezinesivinini esikhulu namaphaneli ezimoto, ukuvaleka komsindo kuseduze nokungu-30dB. Ngokwedatha yokuhlola, izinga lokufakwa komsindo lezikrini ezijwayelekile zomsindo lingancishiswa kuphela ngo-5dB, futhi impahla ye-aluminium eyigwebu ingancishiswa ngo-10-20dB. Ngokusho kokuhlolwa, kuboniswa ukuthi:
| Okubalulekile | Ukucaciswa | Isici Sokunciphisa Umsindo/Inani Lokufakwa Umsindo |
| I-polyurethane foam | 35 mm ubukhulu | I-coefficient yokunciphisa umsindo ngu-0.85NRC |
| I-polyurethane foam | 35 mm ubukhulu | Ukufakwa komsindo kungama-23dB |
| Izinto ze-aluminium foam | 20 mm ubukhulu | I-coefficient yokunciphisa umsindo ngu-0.9NRC |
| Izinto ze-aluminium foam | 20 mm ubukhulu | Ukufakwa komsindo kungama-30dB |
Ngokuthuthukiswa kwezimboni ze-aluminium foam, igwebu le-aluminium lisetshenziswa emikhakheni eminingi ngenxa yokumunca okuphakeme komsindo nokunciphisa umsindo kanye nezakhiwo ezihlobene, njengezithiyo zomsindo womgwaqo, ukuncishiswa komsindo womhubhe womgwaqo, ukuncishiswa komsindo womhubhe ohamba ngaphansi kolwandle, kanye nezikhala zomhubhe; Izindonga zamachibi okubhukuda ezimunca umsindo; umhlobiso wangaphakathi wezindawo zokuzijabulisa;iphansi le-aluminium elinegwebu lokufakwa komsindo; ukukhiqizwa kwe-aluminium eyigwebu yamaloli, izimoto zabagibeli kanye nezinsimbi zemoto; ukukhiqizwa kwe-aluminium eyigwebu yokwakha izintambo ezimunca umsindo, njengezitudiyo zokuqopha, amagumbi okukopisha, amahholo ekhonsathi, amahholo enkomfa, izindawo zezemidlalo nezinye izinkundla, zisebenza kahle kakhulu.
