Mahedifoni oletsa phokoso ndi mtundu wa mahedifoni omwe amachepetsa phokoso kudzera m'njira inayake.
Mahedifoni oletsa phokoso amagwira ntchito pogwiritsa ntchito ma maikolofoni ophatikizika ndi zozungulira zamagetsi kuti athetse phokoso lakunja. Ma maikolofoni omwe ali pamutu amanyamula phokoso lakunja ndikutumiza kumagetsi amagetsi, omwe amapanga mafunde otsutsana kuti athetse phokoso lakunja. Njira imeneyi imadziwika kuti kusokoneza kowononga, kumene mafunde awiri a phokoso amalepheretsana. Chotsatira chake ndi chakuti phokoso lakunja likuchepetsedwa kwambiri, zomwe zimapangitsa kuti wogwiritsa ntchitoyo amve zomwe akumvetsera momveka bwino. Kuphatikiza apo, mahedifoni ena oletsa phokoso amakhalanso ndi phokoso lodzipatula, lomwe limatsekereza phokoso lakunja pogwiritsa ntchito zida zoyamwa m'makutu.
Apanomahedifoni oletsa phokosookhala ndi maikolofoni agawidwa m'njira ziwiri zoletsa phokoso: kuletsa phokoso lokhazikika komanso kuletsa phokoso.
Kuchepetsa phokoso la Passive ndi njira yomwe imachepetsa phokoso m'chilengedwe pogwiritsa ntchito zida kapena zida zinazake. Mosiyana ndi kuchepetsa phokoso, kuchepetsa phokoso sikufuna kugwiritsa ntchito zipangizo zamagetsi kapena masensa kuti azindikire ndi kuthana ndi phokoso. Mosiyana ndi izi, kuchepetsa phokoso lopanda phokoso kumadalira momwe zinthuzo zimapangidwira, kuwonetsera kapena kudzipatula, potero kuchepetsa kufalikira ndi kukhudzidwa kwa phokosolo.
Zomvera zoletsa phokoso zoletsa phokoso makamaka zimapanga malo otsekedwa potseka makutu ndi kugwiritsa ntchito zida zotsekereza mawu monga zotsekera m'makutu za silicon kuti atseke phokoso lakunja. Popanda chithandizo chaukadaulo, chomverera m'makutu cha ofesi yaphokoso chimangoletsa phokoso lambiri, koma sichingachite chilichonse chokhudza phokoso lotsika.
Mfundo yofunikira pakuletsa phokoso logwira ntchito ndi kusokoneza kwa mafunde, komwe kumapangitsa kuti phokoso likhale lopanda phokoso kudzera pamafunde abwino ndi oyipa, kuti akwaniritsezotsatira zoletsa phokoso. Pamene mafunde awiri a mafunde kapena mafunde akumana, kusuntha kwa mafunde awiriwo kudzapangika pamwamba pa wina ndi mzake, ndipo matalikidwe a vibration adzawonjezedwa. Pamene pachimake ndi chigwa, ndi kugwedera matalikidwe a superposition boma adzathetsedwa. ADDASOUND mawaya oletsa phokoso lamutu lagwiritsa ntchito ukadaulo woletsa phokoso.
Pamutu woletsa phokoso kapena phokoso loletsa phokoso la m'makutu, payenera kukhala bowo kapena gawo lina loyang'ana mbali ina ya khutu. Anthu ena amadabwa kuti ndi chani. Gawoli limagwiritsidwa ntchito kusonkhanitsa mawu akunja. Phokoso lakunja likasonkhanitsidwa, purosesa yomwe ili m'makutu idzapanga gwero lotsutsana ndi phokoso lotsutsana ndi phokoso.
Pomaliza, gwero loletsa phokoso ndi mawu omwe amaseweredwa m'makutu amatumizidwa palimodzi, kotero kuti sitingathe kumva phokoso lakunja. Kumatchedwa kuletsa phokoso chifukwa kumatha kutsimikiziridwa mwachinyengo ngati kuwerengera gwero lodana ndi phokoso.
