Noise-cancelling headsets imhando yemahedhifoni anoderedza ruzha kuburikidza neimwe nzira.
Mahedhifoni ekudzimisa ruzha anoshanda nekushandisa musanganiswa wemakrofoni uye magetsi edunhu kudzima ruzha rwekunze. Maikorofoni pahedhiseti inotora ruzha rwekunze uye inotumira kune yemagetsi circuitry, iyo inobva yagadzira yakatarisana neruzha wave kudzima ruzha rwekunze. Kuita uku kunozivikanwa sekukanganisa kunoparadza, uko masaisai maviri eruzha anodzima. Mhedzisiro ndeyekuti ruzha rwekunze rwakaderedzwa zvakanyanya, zvichibvumira mushandisi kuti anzwe zvirimo zveodhiyo zvakanyanya. Pamusoro pezvo, mamwe mahedhifoni ekudzika-ruzha zvakare ane passive ruzha kuparadzaniswa, izvo zvinovharira kunze ruzha rwekunze kuburikidza nekushandiswa kwezvinhu zvinotora ruzha mumikombe yenzeve.
The currentmahedhifoni anobvisa ruzhaine mic yakakamurwa kuita maviri-anokanzura modhi: passive ruzha kudzima uye inoshanda kudzima ruzha.
Passive noise reduction inzira inoderedza ruzha munharaunda kuburikidza nekushandisa chaiyo zvinhu kana michina. Kusiyana neanoshanda kudzikisa ruzha, kungoita ruzha kuderedza hakudi kushandiswa kwemagetsi emagetsi kana masensa kuona uye kurwisa ruzha. Mukupesana, kudzikamisa ruzha kunoenderana nehunhu hwechigadzirwa kuti hutore, kuratidza kana kupatsanura ruzha, nekudaro kuderedza kupararira uye kukanganisa kweruzha.
Passive ruzha-kukanzura mahedhifoni anonyanya kuumba nzvimbo yakavharwa nekuputira nzeve uye kushandisa ruzha-inodzivirira zvinhu senge silicone earplugs kuvhara kunze ruzha. Pasina rubatsiro rwetekinoroji, iyo headset yehofisi ine ruzha inogona chete kuvhara yakakwira-frequency ruzha, asi haigone kuita chero chinhu nezve yakaderera-frequency ruzha.
Iyo inodiwa musimboti weinoshanda ruzha kudzima ndiyo inopindira musimboti wemafungu, ayo anoderedza ruzha kuburikidza neakanaka uye asina kunaka mafungu eruzha, kuitira kuti uwaneruzha-kubvisa maitiro. Kana maviri mafungu crests kana mafungu emvura asangana, kutamiswa kwemafungu maviri kuchaiswa pamusoro peumwe neumwe, uye iyo vibration amplitude ichawedzerwawo. Kana iri pamusoro uye mupata, iyo vibration amplitude ye superposition state ichadzimwa. ADDASOUND wired ruzha kudzima mahedhifoni yashandisa iyo inoshanda ruzha yekudzima tekinoroji.
Paruzha rwekudzima mahedhifoni kana ruzha runoshanda runodzima earphone, panofanira kunge paine buri kana chikamu chayo chakatarisana nedivi renzeve. Vamwe vanhu vanozoshamisika kuti ndeyei. Chikamu ichi chinoshandiswa kuunganidza manzwi ekunze. Mushure mekunge ruzha rwekunze rwaunganidzwa, processor iri munzeve inogadzira inorwisa-ruzha sosi yakatarisana neruzha.
Pakupedzisira, anti-ruzha sosi uye ruzha runoridzwa munzeve zvinofambiswa pamwe chete, kuti tisanzwe ruzha rwekunze. Inonzi active noise cancelling nekuti inogona kutariswa nehunyanzvi kana kuverengera anti-ruzha sosi.
