Njira yotumizira phokoso la mpweya ndi "sound wave - auricle - canal auditory canal - tympanic membrane - malleus - incus - stapes - vestibular window - kunja, endolymph - spiral organ - auditory nerve - auditory center".
The bone conduction sound conduction pathway ndi: "sound wave-cranium-bone labyrinth-inner ear lymph fluid-spiral-auditory nerve-cerebral cortex auditory center".
Mayendedwe a mpweya ayenera kugwiritsa ntchito mphira wa khutu (eardrum) m'khutu la munthu kutumiza kugwedezeka kwa mpweya komwe kumachitika chifukwa cha phokoso ku mitsempha ya khutu mkati mwa khutu kupyolera mu eardrum.Pamene ntchito ya eardrum ikuchepa chifukwa cha ukalamba kapena matenda, izo zingayambitse vuto lakumva kwa munthuyo.
Kuyendetsa fupa, pogwiritsa ntchito mfundo ya kufalikira kwa phokoso la mafupa, kumatulutsa phokoso mwachindunji kupyolera mu chigaza kupita ku mitsempha ya khutu mkati mwa khutu.Chifukwa chakuti mphira ya m’makutu sikufunika, ngakhale kugwira ntchito kwa m’khutu kutsika chifukwa cha ukalamba kapena matenda, kumva sikungakhudzidwe mwa kugwiritsa ntchito fupa la conduction kuti limve phokoso.Uwu ndiye mwayi of fupa conduction zothandizira kumva.
