Mahedhifoni anobvisa ruzhaTekinoroji yepamberi yekuteerera inoderedza zvakanyanya ruzha rusingade, ichipa vashandisi ruzivo rwakanyanya rwekuteerera. Vanozadzisa izvi kuburikidza nemaitiro anodaidzwa kuti Active Noise Control (ANC), ayo anosanganisira akaomesesa emagetsi zvikamu zvinoshanda pamwechete kurwisa kurira kwekunze.
Iyo ANC Technology Inoshanda
Kuonekwa Kwenzwi: Madiki maikorofoni akaiswa mumahedhifoni anotora ruzha rwekunze munguva chaiyo.
Signal Analysis: An onboard digitaalinen siginecha processor (DSP) inoongorora frequency uye amplitude yeruzha.
Anti-Noise Generation: Iyo sisitimu inogadzira inverse sound wave (anti-noise) yakafanana muamplitude asi 180 madhigirii kunze kwechikamu neruzha runouya.
Kupindira Kunoparadza: Kana iyo anti-noise wave yasangana neruzha rwepakutanga, vanodzima mumwe nemumwe kuburikidza nekukanganisa kunoparadza.
Yakachena Audio Output: Mushandisi anongonzwa odhiyo inodiwa (senge mimhanzi kanaizwi rinofona) nekukanganisa kudiki kumashure.
Mhando dzeActive Noise Cancellation
Feedforward ANC: Maikorofoni inoiswa kunze kwekapu dzenzeve, zvichiita kuti ishande kurwisa ruzha rwepamusoro-seruzha sekutaura kana kutaipa.
Mhinduro ANC: Maikorofoni mukati mekapu dzenzeve inotarisisa ruzha rwakasara, kuvandudza kudzima kune yakaderera-frequency inonzwika senge injini inotinhira.
Hybrid ANC: Musanganiswa weiyo feedforward uye mhinduro ANC yekushanda kwakanyanya pama frequency ese.
Advantages & Limitations
Zvazvakanakira:
Yakanakira kufamba (ndege, zvitima) uye nzvimbo dzebasa dzine ruzha.
Inoderedza kuneta kwekuteerera nekuderedza ruzha rwekumashure.
Cons
Kusashanda zvakanaka pazvinongoerekana zvaitika, zvisingaite sekurova maoko kana kuhukura.
Inoda simba rebhatiri, izvo zvinogona kudzikisira nguva yekushandisa.
Nekusimudzira epamberi masaini kugadzirisa uye misimboti yefizikisi,mahedhifoni anobvisa ruzhakuwedzera kujeka kweodhiyo uye kunyaradza. Ingave yekushandiswa kwehunyanzvi kana kutandara, ivo vanoramba vari chishandiso chakakosha chekuvhara kunze zvinokanganisa uye kugadzirisa kutarisa.
ENC mahedhifoni anoshandisa advanced audio processing kuderedza ruzha rwekumashure panguva yekufona uye kutamba odhiyo. Kusiyana nechinyakare ANC (Active Noise Cancellation) iyo inonyanya kunanga inogara yakaderera-frequency kurira, ENC inotarisana nekuzviparadzanisa uye kudzvinyirira kwezvakatipoteredza ruzha kuti uwedzere kujeka kwezwi mune zvekutaurirana mamiriro.
Iyo ENC Technology Inoshanda
Multi-Microphone Array: ENC mahedhifoni anosanganisira akawanda akaiswa zvine hungwaru maikorofoni kubata zvese izwi remushandisi uye ruzha rwakatenderedza.
Noise Analysis: Iyo yakavakirwa-mukati DSP chip inoongorora iyo ruzha chimiro munguva-chaiyo, ichisiyanisa pakati pekutaura kwevanhu nemanzwi ezvakatipoteredza.
Selective Noise Reduction: Iyo sisitimu inoshandisa adapta algorithms kudzvanya ruzha rwekumashure uchichengetedza manzwi ezwi.
Beamforming Technology: Mamwe mahedhifoni eENC epamberi anoshandisa maikorofoni anotungamira kutarisa paizwi remutauri uku uchideredza ruzha rwe-axis.
Output Optimization: Iyo yakagadziridzwa odhiyo inopa yakajeka kutapurirana kwezwi nekuchengetedza kunzwisisika kwekutaura uye kuderedza zvinokanganisa manzwi.
Misiyano Yakakosha kubva kuANC
Target Application: ENC inyanzvi mukutaurirana kwezwi (kufona, misangano), nepo ANC ichikunda mumhanzi/nzvimbo dzekuteerera.
Noise Handling: ENC inobata zvinonzwika ruzha rwakasiyana senge traffic, kutaipa kiyibhodhi, uye chatter yeruzhinji iyo ANC inonetsekana nayo.
Processing Focus: ENC inokoshesa kuchengetedza kutaura kwete kudzima ruzha rwakakwana.
Nzira dzekuita
Digital ENC: Inoshandisa software algorithms yekudzvinyirira ruzha (yakajairika muBluetooth mahedhifoni).
Analog ENC: Inoshandisa hardware-level kusefa (inowanikwa mune wired professional headsets).
Performance Factors
Maikorofoni Hunhu: High-sensitivity mics inovandudza ruzha rwekutora kurongeka.
Processing Power: Inokurumidza DSP machipi inogonesa yakaderera latency ruzha kudzima.
Algorithm Sophistication: Michina yekudzidza-yakavakirwa masisitimu inogadzirisa zvirinani kune inoshanduka ruzha nharaunda.
Applications
Bhizinesi kutaurirana (kufona kwemusangano)
Contact centre mashandiro
Mahedhifoni ekutamba nekutaura kwezwi
Mabasa emumunda munzvimbo dzine ruzha
ENC tekinoroji inomiririra yakasarudzika nzira yekutonga ruzha, optimize mahedhifoni ekufambisa kwezwi kwakajeka kwete kupedzisa ruzha. Sezvo basa riri kure uye kutaurirana kwedhijitari kuchikura, ENC inoenderera mberi nekuvandudzwa neAI-inofambiswa nekuvandudzwa kwezwi riri nani munzvimbo dziri kuwedzera dzine ruzha.
