Unyango lokuphazamiseka kwegumbi lovavanyo lobushushu obuphezulu nobuphantsi luchazwe ngokucacileyo kwi-GJB 150, eyahlula ukuphazamiseka kovavanyo kwiimeko ezintathu, oko kukuthi, ukuphazamiseka ngaphakathi koluhlu lokunyamezelana, ukuphazamiseka phantsi kweemeko zovavanyo kunye nokuphazamiseka phantsi kweemeko zovavanyo ezigqithisileyo. Iimeko ezahlukeneyo zineendlela ezahlukeneyo zonyango.
Xa kuphazamiseka ngaphakathi koluhlu lokunyamezelana, xa iimeko zovavanyo zingadluli kuluhlu lweempazamo ezivumelekileyo ngexesha lokuphazamiseka, ixesha lokuphazamiseka kufuneka lithathwe njengenxalenye yexesha elipheleleyo lovavanyo; xa kuphazamiseka phantsi kweemeko zovavanyo, xa iimeko zovavanyo zegumbi lovavanyo lobushushu obuphezulu nobuphantsi ziphantsi kunomda ophantsi wempazamo evumelekileyo, iimeko zovavanyo ezichazwe kwangaphambili kufuneka zifikelelwe kwakhona ukusuka kwindawo engaphantsi kweemeko zovavanyo, kwaye uvavanyo kufuneka luqaliswe kwakhona de kube umjikelo wovavanyo olucwangcisiweyo ugqityiwe; xa kuvavanywa ngokugqithisileyo, ukuba iimeko zovavanyo olugqithisileyo aziyi kuchaphazela ngokuthe ngqo ukuphazamiseka kweemeko zovavanyo, ukuba isampuli yovavanyo iyasilela kuvavanyo olulandelayo, iziphumo zovavanyo kufuneka zithathwe njengezingasebenziyo.
Kwimisebenzi yokwenyani, sisebenzisa indlela yokuvavanya kwakhona emva kokuba isampuli yovavanyo ilungisiwe ngenxa yokuphazamiseka kovavanyo okubangelwe kukusilela kwesampuli yovavanyo; ngenxa yokuphazamiseka kovavanyo okubangelwa kukuphakama nokusezantsi.uvavanyo lobushushu kwigumbi lovavanyoizixhobo ze-t (ezifana nokucinywa kwamanzi ngequbuliso, ukucinywa kombane, ukungasebenzi kwezixhobo, njl.njl.), ukuba ixesha lokuphazamiseka alide kakhulu (ngaphakathi kweeyure ezi-2), sihlala sijongana nalo ngokwemeko yokuphazamiseka engaphantsi kovavanyo echazwe kwi-GJB 150. Ukuba ixesha lide kakhulu, uvavanyo kufuneka luphindwe. Isizathu sokusebenzisa amalungiselelo onyango lokuphazamiseka kovavanyo ngale ndlela simiselwa ngamalungiselelo okuzinza kobushushu besampulu yovavanyo.
Ukumiselwa kobude bobushushu bovavanyo kwiindawo eziphezulu nezisezantsiigumbi lovavanyo lobushushuUvavanyo lobushushu ludla ngokusekwe kwisampulu yovavanyo efikelela kuzinzo lobushushu kolu bushushu. Ngenxa yokwahluka kwisakhiwo semveliso kunye nezixhobo kunye nobuchule bezixhobo zovavanyo, ixesha leemveliso ezahlukeneyo ukufikelela kuzinzo lobushushu kubushushu obufanayo lahlukile. Xa umphezulu wesampulu yovavanyo ushushu (okanye upholisiwe), udluliselwa kancinci kancinci ngaphakathi kwesampulu yovavanyo. Inkqubo enjalo yokuqhuba ubushushu yinkqubo yokuqhuba ubushushu ezinzileyo. Kukho ixesha eliphakathi kwexesha apho ubushushu bangaphakathi besampulu yovavanyo bufikelela kumlinganiselo wobushushu kunye nexesha apho umphezulu wesampulu yovavanyo ufikelela kumlinganiselo wobushushu. Eli xesha liphakathi lixesha lokuqina kobushushu. Ixesha elincinci elifunekayo kwiisampulu zovavanyo ezingenakulinganisa uzinzo lobushushu lichaziwe, oko kukuthi, xa ubushushu bungasebenzi kwaye bungenakulinganiswa, ixesha elincinci lokuqina kobushushu ziiyure ezi-3, kwaye xa ubushushu busebenza, ixesha elincinci lokuqina kobushushu ziiyure ezi-2. Kumsebenzi wokwenyani, sisebenzisa iiyure ezi-2 njengexesha lokuqina kobushushu. Xa isampuli yovavanyo ifikelela kuzinzo lobushushu, ukuba ubushushu obujikeleze isampuli yovavanyo butshintsha ngequbuliso, isampuli yovavanyo kwi-thermal equilibrium nayo iya kuba nexesha elide, oko kukuthi, ngexesha elifutshane kakhulu, ubushushu obungaphakathi kwisampuli yovavanyo abuyi kutshintsha kakhulu.
Ngexesha lovavanyo lokufuma kubushushu obuphezulu nobuphantsi, ukuba kukho ukucinywa kwamanzi ngequbuliso, ukucinywa kombane okanye ukungasebenzi kwezixhobo zovavanyo, kufuneka siqale sivale ucango lwegumbi lovavanyo. Kuba xa izixhobo zovavanyo lokufuma kubushushu obuphezulu nobuphantsi ziyeka ukusebenza ngequbuliso, lo gama nje ucango lwegumbi luvaliwe, ubushushu bocango lwegumbi lovavanyo abuyi kutshintsha kakhulu. Ngexesha elifutshane kakhulu, ubushushu ngaphakathi kwesampulu yovavanyo abuyi kutshintsha kakhulu.
Emva koko, misela ukuba olu phazamiseko lunempembelelo na kwisampulu yovavanyo. Ukuba aluchaphazeli isampulu yovavanyo kunyeizixhobo zovavanyosingaqalisa kwakhona ukusebenza okuqhelekileyo ngexesha elifutshane, singaqhubeka novavanyo ngokwendlela yokuphatha ukuphazamiseka kweemeko zovavanyo ezinganelanga ezichazwe kwi-GJB 150, ngaphandle kokuba ukuphazamiseka kovavanyo kunempembelelo ethile kwisampulu yovavanyo.
