Emishinini yomsindo, ukuzwela kwemishini yesipikha kubizwa ngokuthi ikhono layo lokuguqula ugesi ube umsindo noma umsindo ube ugesi.

Kodwa-ke, izinga lokuzwela ezinhlelweni zomsindo zasekhaya alihlobene ngqo noma alithonywa yikhwalithi yomsindo.

Akunakuthathwa kalula noma ngokweqile ukuthi uma ukuzwela kwesipikha kuphakeme, kulapho ikhwalithi yomsindo iba ngcono. Yiqiniso, akunakuphikwa ngqo ukuthi isipikha esinokuzwa okuphansi kumele sibe nekhwalithi yomsindo ephansi. Ukuzwela kwesipikha kuvame ukuthatha u-1 (watt, W) njengamandla esignali yokufaka. Beka imakrofoni yokuhlola imitha eli-1 ngqo phambi kwesipikha, futhi ukuze uthole isipikha esinezindlela ezimbili, beka imakrofoni phakathi kwamayunithi amabili esipikha. Isiginali yokufaka iyisignali yomsindo, futhi izinga lokucindezela komsindo elilinganisiwe ngalesi sikhathi ukuzwela kwesipikha.

Isikhulumi esinempendulo ebanzi yemvamisa sinamandla amakhulu okuveza, ukuzwela okuphezulu kwenza kube lula ukuzwakala, amandla aphezulu asenza sizinze futhi siphephile, sinama-curve alinganiselayo kanye nokuxhumeka kwesigaba okunengqondo nokufanelekile, okungeke kubangele ukuphazamiseka ngenxa yokusetshenziswa kwamandla kwangaphakathi. Ngakho-ke, singaphinda sikhiqize imisindo ehlukahlukene ngokweqiniso nangokwemvelo, futhi umsindo unomuzwa onamandla wokuhlelwa, ukuhlukaniswa okuhle, ukukhanya, ukucaca, kanye nobumnene. Isikhulumi esinozwela oluphezulu namandla aphezulu asilula nje kuphela ukuzwakala, kodwa okubaluleke kakhulu, izinga laso eliphezulu lokucindezela umsindo ngaphakathi kwebanga elizinzile neliphephile "lingakwazi ukudlula isixuku", futhi izinga lokucindezela umsindo elidingekayo lingatholakala ngaphandle kokudinga amandla amaningi kakhulu ukushayela.

Kunezinhlobo eziningi ezidumile zezikhulumi ezithembekile emakethe, kodwa ukuzwela kwazo akuphezulu (phakathi kuka-84 no-88 dB), ngoba ukwanda kokuzwela kuza ngezindleko zokwanda kokuhlanekezela.

Ngakho-ke njengesikhulumi esithembekile, ukuze kuqinisekiswe izinga lokukhiqiza umsindo kanye nekhono lokukhiqiza umsindo, kubalulekile ukunciphisa ezinye izidingo zokuzwela. Ngale ndlela, umsindo ungalinganiswa ngokwemvelo.

Ingabe ukuzwela kohlelo lomsindo kuphakeme, kungcono, noma kungcono ukuba phansi?

Uma ukuzwela kuphakeme, kuba ngcono. Uma ukuzwela kwesipikha kuphakeme, kulapho izinga lokucindezela komsindo wesipikha ngaphansi kwamandla afanayo liphakama khona, futhi kulapho umsindo okhishwa yisipikha uphakama khona. Izinga lokucindezela komsindo elikhiqizwa yidivayisi endaweni ethile ezingeni elithile lokufaka (amandla). Izinga lokucindezela komsindo=10 * amandla elogi+ukuzwela.

Ngokuyisisekelo, ngokuphindwe kabili ngakunye kwezinga lokucindezela komsindo, izinga lokucindezela komsindo likhuphuka ngo-1dB, kodwa ngokunyuka ngakunye kokuzwela okungu-1dB, izinga lokucindezela komsindo lingakhuphuka ngo-1dB. Kulokhu, ukubaluleka kokuzwela kungabonakala. Embonini yomsindo yobungcweti, i-87dB (2.83V/1m) ibhekwa njengepharamitha ephansi futhi ngokuvamile ingeyama-speaker amancane (amasentimitha angu-5). Ukuzwela kwezikhulumi ezingcono kuzodlula u-90dB, kanti ezinye zingafinyelela ngaphezu kuka-110. Ngokuvamile, uma usayizi wesipika mkhulu, kulapho ukuzwela kuphakeme khona.
