Mahedhifoni ane inomhanyisa kudzima tekinoroji inorova pamusika seimwe nzira yevanoshanda uye/kana kufamba munzvimbo dzine ruzha (senge nhandare dzendege), vanoda kujekeserwa kweruzha kuti vatambe mimhanzi yavo kana podcasts pasina zvinokanganisa zvekunze. Kune akasiyana mahedhifoni pamusika neiyi tekinoroji ruzha kudzima (kudzima ruzha, muchiPutukezi), asi tekinoroji iyi inoshanda sei? 62735a
Chii chinonzi kudzima ruzha 1a4z25
Kuti tifambire mberi mune tekinoroji, tinofanira kutanga tanzwisisa zvishoma kuti sei mafungu eruzha shanda. Ruzha runoumbwa nemasaisai emuchina anoparadzirwa nemhepo. Kana mhepo ikashandiswa nechinhu chinoburitsa ruzha, chiri kuzunguzika, inokura uye inokondirana. Mhepo ine nhungamiro uye kubva pakatanga ruzha, iyi wave inogona kukwira (positive phase) kana pasi (negative phase).
Noise cancellation technology iyo yakanga ine patent yakagadzirwa muna 1930 uye yekutanga prototype yakatangwa muna 1986, inoshandisa kupindira kunoparadza, izvo zvinoitika kana masaisai maviri abatanidzwa. Mune mamwe mazwi, nepo masaisai ari muchikamu chakanaka achikwira kumusoro uye achiwedzera mhepo, kune masaisai ari muchikamu chisina kunaka anoenda pasi uye achibvumirana nemhepo. Nekuda kweizvozvo, masaisai anodzima mumwe nemumwe kunze, mhepo inooma mitezo uye kunenge kunyarara kunogadzirwa, zvichikutendera kuti uteerere mimhanzi pasina kukanganisa.
Mashandisiro anoita tekinoroji mumahedhifoni ako 5v5h5y
Mahedhifoni ane ruzha kudzima vanodzima ruzha rwuya rwunogona kupfuura nekuzviparadzanisa nevamwe, tekinoroji inowanikwa mumahedhifoni mazhinji anogadzirwa, achitevera mamodheru uye zvinhu, senge high-density foam, iyo inovhara zvishoma mafungu ekunze. Iwe in-ear headphones Iwo muenzaniso wekuzviparadzanisa nevamwe, asi nekuda kwekuenderana nenzeve nenzeve, vanoguma vasingashumire vese vashandisi zvakaenzana.
Nekudaro, tekinoroji iyi inoshanda zvakanyanya kune yakaderera-frequency uye inonzwika ruzha. Muchidimbu, mafungu eruzha epamusoro-soro (manzwi epamusoro) zvinobuda zvishoma zvishoma. Izvi zvinoitika nekuti mumahedhifoni ane kushingaira kudzima ruzha, maikorofoni anovakwa mumahedhifoni uye anoona manzwi ekunze uye anoashandura kuita chiratidzo chemagetsi. Nenzira iyi, dunhu rine maikorofoni rinotora ruzha ruchadzimwa uye imwe dunhu ichaverengera akasiyana mavhezheni eiyi manzwi - kuverenga uku kunogona kutora mamicroseconds kuti aitwe uye nekudaro kushanda kwehunyanzvi kwakakura mukugara, kuderera. -frequency manzwi..
Mamwe mahedhifoni ane kushingaira kudzima ruzha anogona kunge ane ruzha runooneka. Iyi hiss inogadzirwa nemagetsi emagetsi pachayo ayo, nekushayikwa kwekufanana mumagetsi uye waya yemhangura, inokonzera maerekitironi kusvetuka, zvichiita kuti ruzha urwu ruve - rwuripo mumafoni uye kunyange amplifiers. Uye izvi zvakabatana nemhando yemahedhifoni zvakare. Pane zvingasarudzwa pamusika apo kudzima ruzha kunoshanda zvakanyanya, senge WH - 1000XM3, ipapo Sony.
Kune avo vari kutsvaga madiki ehedhifoni sarudzo nehunyanzvi, iwo WF-100XM3, ipapo Sony, inokurudzirwa kubatanidza tekinoroji nekuita kwe earbuds (mahedhifoni asina waya, muchiPutukezi).
Nekudaro, mune ramangwana isu tingasatomboda zvishandiso munzeve dzedu kuti tinakirwe nemabhenefiti ekuita ruzha kudzima. Cars nema accelerometers akasanganiswa nemamaikorofoni kuti ayananisire kutenheka kweruzha rwekunze, vanototsvaga kuderedza ruzha rwunonzwikwa nevafambi. Mainjiniya paYunivhesiti yeI Illinois varikutsvagirawo nzira yekubatanidza inoshanda ruzha kudzima tekinoroji nemasaini asina waya anofambiswa miriyoni nekukurumidza kupfuura ruzha.
Kusvikira ramangwana rasvika, kana iwe uchida kuteerera mimhanzi yako pasina kukanganisa kwekunze, ruzha-kukanzura mahedhifoni ndiyo yakanyanya kunaka sarudzo kwauri. Tora mukana wematipi edu uye unyure zvakadzika mune ino denga.
Iye zvino zvaunoziva kuti tekinoroji iyi inoshanda sei, tarisa yedu runyorwa rwekurudziro:
