Emishini yokulalelwayo, ukuzwela kwemishini yesipika kubhekiselwa kuwo njengekhono layo lokuguqula ugesi kuzwakale noma kuzwakale ugesi.

Kodwa-ke, izinga lokuzwela ezinhlelweni zomsindo wasekhaya alihlobene ngqo noma lithonywe yikhwalithi yomsindo.

Akunakuba nje noma kucatshangwe ngokweqile ukuthi ukukhuphuka kwesipika, ikhwalithi yomsindo engcono. Vele, angeke ukwenqatshelwe ngokuqondile ukuthi isikhulumi esinokuzwela okuphansi kumele kube nekhwalithi ephezulu yomsindo. Ukuzwela kwesipika kuvame ukuthatha i-1 (watt, w) njengamandla wesiginali wokufaka. Faka imakrofoni eyi-1 yokuhlola ngqo phambi kwesipika, kanye nesipika sezindlela ezimbili ezigcwele uhla, faka imakrofoni phakathi kwamayunithi amabili kaSomlomo. Isiginali yokufaka iyisiginali yomsindo, kanye nezinga elilinganisiwe lengcindezi yomsindo ngalesi sikhathi ukuzwela kwesipika.

Isikhulumi esinempendulo ebanzi yemvamisa sinamandla aqinile abonisa amandla, ukuzwela okuphezulu kwenza kube lula ukukhala, amandla aphezulu kwenza kube ezinzile futhi kuphephile, okuvunyelwe kanye nokuxhumeka kwesigaba esilinganiselwe, okungeke kubengelwa ukuphazamiseka ngenxa yokusetshenziswa kwamandla kwangaphakathi. Ngakho-ke, ingahlukanisa ngokweqiniso ngokweqiniso imisindo ehlukahlukene, futhi umsindo unomuzwa oqinile wokuphambana, ukwahlukana okuhle, ukukhanya, ukucaca, ukucaca nokuthamba. Isikhulumi esinokuzwela okuphezulu namandla aphezulu akulula nje ukukhala, kepha okubaluleke kakhulu, izinga layo eliphakeme kakhulu lengcindezi elisezingeni eliphakathi nendawo "lingatholwa isixuku", futhi izinga lokucindezela umsindo olidingekayo lingatholakala ngaphandle kokufuna amandla amaningi okushayela.

Kunemikhiqizo eminingi eyaziwayo yezikhulumi eziphakeme zokwethembeka emakethe, kepha ukuzwela kwazo akuphezulu (phakathi kwama-84 no-88 db), ngoba ukwanda kokuzwela kuza ngezindleko zokwanda.

Ngakho-ke njengesikhulumi esiphezulu solethekile, ukuze kuqinisekiswe izinga lokuzala kabusha komsindo kanye nekhono lokukhiqiza kabusha, kuyadingeka ukunciphisa ezinye izidingo zokuzwa. Ngale ndlela, umsindo ungalinganisela ngokwemvelo.

Ingabe ukukhuphuka kokuzwela kohlelo lomsindo, okungcono, noma kungcono ukwehla?

Ukukhuphuka uzwela, okungcono. Lapho ukhula uzwela lwesipika, ukukhuphuka kwezinga lokucindezela komsindo wesipika ngaphansi kwamandla afanayo, futhi kukhulu umsindo okhishwa yisomlomo. Izinga lengcindezi yomsindo ekhiqizwa yidivaysi endaweni ethile esezingeni elithile lokufaka (amandla). Izinga lengcindezi yomsindo = 10 * Amandla we-Log Amandla + azwakala.

Ngokuyisisekelo, ngakho konke ukuphindaphindwa kwenqanaba lengcindezi yomsindo, izinga lokucindezela umsindo likhuphuka nge-1DB, kepha kulo lonke elandayo le-1DB lokuzwela, izinga lokucindezela umsindo lingakhula nge-1DB. Kulokhu, ukubaluleka kokuzwela kungabonakala. Embonini yomsindo ochwepheshe, 87DB (2.83V / 1m) kubhekwa njengepharamitha ephansi futhi ngokuvamile okungokwabakhulumi obukhulu (amasentimitha ama-5). Ukuzwela kwezikhulumi ezingcono kuzodlula i-90DB, kanti abanye bangafinyelela ngaphezulu kwe-110. Ngokuvamile ukukhuluma, ubukhulu usayizi wesipikathi, kuphakama ukuzwela
