Ijubane lomsindo ijubane lokusabalalisa lokuphazamiseka kwengcindezi ebuthakathaka phakathi nendawo, futhi ubukhulu bayo buhluka ngokuya ngemvelo kanye nesimo se-medium. Ijubane lomsindo emoyeni licishe libe ngu-340 m/s ku-1 standard atmospheric pressure kanye no-15°C.
Isivinini sokusabalalisa segagasi lomsindo ku-elastic medium isivinini somsindo, uphawu lwayo ngu-c, iyunithi ngu-m/s: c=λf
Kufomula, f imvamisa yokudlidliza, okungukuthi, inombolo yokudlidliza ngomzuzwana, Hz: λ ubude begagasi, m.
Ngenxa yokuthi akukho ukunwebeka kwe-shear kugesi, ukunwebeka kwevolumu kuphela, ngakho-ke indlela yokusabalalisa igesi ingaba amagagasi e-longitudinal kuphela. Ngamanye amazwi, ngaphansi kokuphazamiseka kwamagagasi omsindo, izinhlayiya endaweni yegesi ziyandindizela eduze nendawo yazo yokulinganisa, zenze inqubo yokudlulisela elandelanayo eminyene futhi eyingcosana. Ngesikhathi esifanayo, ukuqondisa okuhambayo kwezinhlayiyana kufana nesiqondiso sokusabalalisa kwegagasi. Ngokuvamile, ukuvezwa kwesivinini somsindo wegesi ngaphansi kwanoma yiziphi izimo kuyinkimbinkimbi kakhulu. Isisho saso sihlobene nesisindo se-molecular mass, umthamo wokushisa othize, nezibalo zezakhiwo zegesi, futhi ngeke zethulwe lapha. Ezinkingeni ezijwayelekile, ifomula yesivinini somsindo wegesi efanelekile ivame ukusetshenziswa.
Kungafakazelwa ukuthi isivinini somsindo kugesi ekahle yilena: c=(rp/p)0.5 Kufomula, i-r adiabatic coefficient ilingana nesilinganiso somthamo wokushisa ekucindezelweni okuqhubekayo kumthamo wokushisa ngokucindezela njalo; p ingcindezi yegesi, Pa; ρ ukuminyana, kg/m3.
