Amahedisethi akhansela umsindo awuhlobo lwamahedisethi anciphisa umsindo ngendlela ethile.
Amahedisethi akhansela umsindo asebenza ngokusebenzisa inhlanganisela yemakrofoni nokujikeleza kwe-elekthronikhi ukukhansela ngokuqhubekayo umsindo wangaphandle. Amamakrofoni kumahedisethi athatha umsindo wangaphandle futhi awuthumele kumjikelezo we-elekthronikhi, obese udala igagasi lomsindo elihlukile ukuze likhansele umsindo wangaphandle. Le nqubo yaziwa ngokuthi ukuphazamiseka okulimazayo, lapho amagagasi omsindo amabili ekhansela khona. Umphumela uba ukuthi umsindo wangaphandle unciphe kakhulu, okuvumela umsebenzisi ukuthi ezwe okuqukethwe komsindo wakhe ngokucacile. Ukwengeza, amanye amahedisethi akhansela umsindo nawo anomsindo ongashintshi, ovimba umsindo wangaphandle ngokusetshenziswa kwezinto ezimunca umsindo ezinkomishini ezindlebeni.
Okwamanjeamahedisethi asusa umsindongemakrofoni ihlukaniswe yaba izindlela ezimbili zokukhansela umsindo: ukukhansela umsindo onganyakazi kanye nokukhansela umsindo osebenzayo.
Ukuncishiswa komsindo okungenzi lutho kuyindlela enciphisa umsindo endaweni ngokusebenzisa izinto ezithile noma amadivaysi. Ngokungafani nokuncishiswa komsindo okusebenzayo, ukuncishiswa komsindo okwenziwayo akudingi ukusetshenziswa kwezinto zikagesi noma izinzwa ukuze kutholwe futhi kuliwe nomsindo. Ngokuphambene, ukuncishiswa komsindo okwenziwayo kuncike ezimpahleni ezibonakalayo zezinto ezibonakalayo ukuze zimunce, zibonise noma zihlukanise umsindo, ngaleyo ndlela kwehlise ukusakazeka nomthelela womsindo.
Amahedisethi akhanyisa umsindo ngokuyinhloko akha isikhala esivaliwe ngokuvala izindlebe futhi asebenzise izinto ezivimbela umsindo njengama-earplugs we-silicone ukuvimba umsindo wangaphandle. Ngaphandle kosizo lobuchwepheshe, ihedisethi yehhovisi elinomsindo ingavimba kuphela umsindo we-high-frequency, kodwa ayikwazi ukwenza lutho ngomsindo we-low-frequency.
Umgomo odingekayo wokukhanselwa komsindo osebenzayo umgomo wokuphazanyiswa kwamagagasi, okwenza umsindo ube lula ngamagagasi omsindo avumayo noma angalungile, ukuze kuzuzweumphumela wokukhansela umsindo. Uma kuhlangana amagagasi amabili noma amagagasi amagagasi, ukugudluzwa kwamagagasi amabili kuzobekwa phezulu komunye nomunye, futhi nokuphakama kokudlidliza nakho kuzokwengezwa. Uma usesiqongweni nasesigodini, i-amplitude yokudlidliza yesimo se-superposition izokhanselwa. I-ADDASOUND ihedisethi yokukhansela umsindo enentambo isebenzise ubuchwepheshe obusebenzayo bokukhansela umsindo.
Kumahedsethi akhansela umsindo osebenzayo noma i-earphone ekhansela umsindo osebenzayo, kufanele kube nembobo noma ingxenye yayo ebheke ngakolunye uhlangothi lwendlebe. Abanye abantu bazozibuza ukuthi ngenzani. Le ngxenye isetshenziselwa ukuqoqa imisindo yangaphandle. Ngemuva kokuthi umsindo wangaphandle usuqoqwe, iphrosesa ku-earphone izodala umthombo ophikisana nomsindo ngokuphambene nomsindo.
Ekugcineni, umthombo wokulwa nomsindo nomsindo odlalwa kuma-earphone kuhanjiswa ndawonye, ukuze singezwa umsindo wangaphandle. Kubizwa ngokuthi ukukhanselwa komsindo okusebenzayo ngoba kunganqunywa ngokwenziwa ukuthi kubalwe yini umthombo wokulwa nomsindo.
