Ukukhethwa koKufudumeza rhoqo kwe Umbhobho wokufudumeza iziko

Ukufudumeza okuphindaphindiweyo kwesithando somlilo sombhobho kunobudlelwane obukhulu kunye nobubanzi bombhobho, kwaye ubunzulu bokungena kobushushu kufuneka buqinisekiswe. Ekubeni inkqubo ifuna ukuba umahluko weqondo lobushushu phakathi kweendonga zangaphakathi nangaphandle zombhobho ungaphantsi okanye ulingana ne-10 degrees celcius, xa i-frequency ingu-1000Hz, ubunzulu bangoku bokungena kombhobho wokusebenza yi-1.2mm kuphela. Ukwandisa ngokufanelekileyo ubunzulu bokungena kwangoku kunye nokuqinisekisa ukuhluka kweqondo lokushisa phakathi kweendonga zangaphakathi nangaphandle, kuyimfuneko ukunciphisa i-frequency intermediate. I-frequency izimisele ukuba yi-800 ukuya kwi-1000 Hz.
