Basa rekuderedza ruzhayakakosha kune headset. Imwe ndeyokuderedza ruzha uye kudzivisa kukwidziridzwa kwakanyanyisa kwevhoriyamu, kuitira kuderedza kukuvara kwenzeve. Yechipiri ndeyekusefa ruzha kuti uvandudze ruzha uye kunaka kwekufona.
Kuderedza ruzha kunogona kukamurwa kuita kungoita uye kunoshanda kuderedza ruzha.
Passive ruzha kuderedza zvakarekuderedza ruzha rwemuviri, passive ruzha kuderedza kunoreva kushandiswa kwehunhu hwemuviri kuparadzanisa ruzha rwekunze kubva munzeve, kunyanya kuburikidza nedhizaini yemusoro wehedhiseti yakasimba, acoustic optimization yenzeve muffs cavity, nzeve muffs mukati meizwi absorption zvinhu uye zvichingodaro. pamusoro pekuwana iyo yemuviri ruzha insulation yemahedhifoni. Kuderedza ruzha kunoshanda zvakanyanya mukuparadzanisa ruzha rwepamusoro (senzwi remunhu), uye kazhinji inoderedza ruzha ne15-20dB.
Active kudzikisa ruzha ndiyo huru yekudzikisa ruzha tekinoroji ANC,ENC, CVC, DSP uye zvichingodaro apo vatengesi vanosimudzira basa rekudzikisa ruzha rwemahedhifoni.
ANC ruzha kuderedza
ANC Active Noise Control (Active Noise Control) inoshanda pamusimboti wekuti maikorofoni inounganidza yekunze ruzha rwekunze, uyezve sisitimu inoishandura kuita inverted ruzha wave uye inoiwedzera kumagumo enyanga. Ruzha rwekupedzisira rwunonzwikwa nenzeve yemunhu ndeichi: Ambient noise + contra-phase ambient ruzha, mhando mbiri dzeruzha rwakakwirirwa kuti uwane kudzikisira kwekunzwa, mubatsiri ndiwe.
Active kudzikisa ruzha inogona kukamurwa kuita feedforward inoshanda kudzikisa ruzha uye mhinduro inoshanda yekudzikisa ruzha zvinoenderana nenzvimbo dzakasiyana dzepikicha maikorofoni.
ENC kudzikisa ruzha
ENC (Environmental Noise Cancellation) kudzima kunoshanda kwe90% yeambient ruzha reversal, nekudaro ichidzikisa ruzha rwepamhepo kusvika pahupamhi hwe35dB, zvichibvumira vatambi kuti vataure vakasununguka nezwi. Kuburikidza nembiri yemakrofoni array, iko kuverengera chaiko kwechinzvimbo chemutauri, uku uchidzivirira iyo huru yekunongedza kutaura, bvisa marudzi ese eruzha rwekukanganisa munharaunda.
DSP kudzikisa ruzha
DSP ipfupi pakugadzirisa masaini edhijitari. Kunyanya kune yakakwirira uye yakaderera frequency ruzha. Pfungwa yacho ndeyekuti maikorofoni inotora ruzha kubva kunharaunda yekunze, uyezve sisitimu inokopa reverse sound wave yakaenzana neruzha rwekutenderera, kudzima ruzha uye kuwana zvirinani kuderedza ruzha. Nheyo yeDSP yekudzikisa ruzha yakafanana neANC kudzikisa ruzha. Nekudaro, iyo yakanaka uye yakaipa ruzha rweDSP inodzima mumwe nemumwe zvakananga muhurongwa.
CVC kuderedza ruzha
Clear Voice Capture (CVC) izwi software yekudzikisa ruzha tekinoroji. Kunyanya kune echo inogadzirwa panguva yekufona. Iyo yakazara-duplex maikorofoni ruzha kudzima software inopa kufona echo uye ambient ruzha kudzima mabasa, inova ndiyo yakanyanya kukwirira kuderedza ruzha pakati peBluetooth foni mahedhifoni.
DSP tekinoroji (kubvisa ruzha rwekunze) inonyanya kubatsira mushandisi wemusoro, nepo CVC (kubvisa echo) inonyanya kubatsira rimwe divi rehurukuro.
