Te mahi owhakaiti haruruhe mea tino nui mo te pane.Ko tetahi ko te whakaiti i te ngangau me te karo i te whakakaha nui o te rōrahi, kia iti ai te kino o te taringa.Ko te tuarua ko te tātari haruru kia pai ake te oro me te kounga waea.
Ka taea te wehewehea te whakaheke haruru ki te whakaheke haruru hohe me te haruru kaha.
Ko te whakaiti haruru hāngū hokiwhakaiti haruru tinana, Ko te whakaheke haruru haruru e pa ana ki te whakamahi i nga ahuatanga o te tinana ki te wehe i te haruru o waho mai i te taringa, ko te nuinga na roto i te hoahoa o te mahunga o te pane kia pai ake, te arotautanga oro o te rua o nga taringa, nga muffs o roto o nga taonga oro me era atu. i runga ki te whakatutuki i te haruru oro tinana o nga pane.He tino whai hua te whakaheke haruru haruru ki te wehe i nga oro auau teitei (penei i te reo tangata), me te nuinga o te waa ka whakaiti i te haruru ma te 15-20dB.
Ko te whakaheke haruru kaha ko te hangarau whakaheke haruru matua ANC,ENC, CVC, DSP me etahi atu i te wa e whakatairanga ana nga kaihokohoko i te mahi whakaiti haruru o nga pane.
Te whakaheke haruru ANC
ANC Active Noise Control (Active Noise Control) e mahi ana i runga i te kaupapa ka kohia e te hopuoro te haruru ambient o waho, katahi ka huri te punaha ki te ngaru oro hurihuri ka taapiri atu ki te pito haona.Ko te oro whakamutunga ka rangona e te taringa tangata ko: Haruru Ambient + haruru ambient contra-phase, e rua nga momo haruru kua whakakikoruatia ki te whakaiti i te haruru tairongo, ko ia ano te tangata e whai hua ana.
Ka taea te wehewehea te whakaheke haruru kaha ki te whakaheke haruru hohe whangai whakamua me te whakahoki korero whakaheke haruru hohe e ai ki nga waahi rereke o te hopuoro hopuoro.
Te whakaiti haruru ENC
Ko te ENC (Environmental Noise Cancellation) he whakakorenga whai hua o te 90% o te hurihanga haruru ambient, na reira ka whakaiti i te haruru ambient ki te 35dB teitei, ka taea e nga kaitakaro te whakawhitiwhiti korero ma te reo.Na roto i te huinga hopuoro rua, te tataunga tika o te tuunga o te kaikorero, i te wa e tiaki ana i te whaikorero aronga matua, tango i nga momo haruru pokanoa i te taiao.
DSP whakaiti haruru
He poto te DSP mo te tukatuka tohu mamati.Ko te nuinga mo te haruru auau teitei me te iti.Ko te whakaaro ka kohia e te hopuoro te haruru mai i te taiao o waho, katahi ka kape te punaha i te ngaru oro whakamuri e rite ana ki te haruru ambient, ka whakakore i te haruru me te pai ake o te heke haruru.Ko te kaupapa o te whakaheke haruru DSP he rite ki te whakaheke haruru ANC.Heoi, ko te haruru pai me te kino o te DSP ka whakakore tika tetahi ki tetahi i roto i te punaha.
CVC haruru whakaiti
Ko te Clear Voice Capture (CVC) he kaupapa hangarau whakaheke haruru reo.Ko te nuinga mo te paoro i hangaia i te wa o te waea.Ko te raupaparorohiko whakakore haruru o te hopuoro matarua-katoa e whakarato ana i te paoro waea me nga mahi whakakore haruru ambient, koinei te tino hangarau whakaheke haruru i waenga i nga pane waea Nihokikorangi.
Ko te hangarau DSP (te whakakore i te haruru o waho) ka whai hua te nuinga ki te kaiwhakamahi pane, ko te CVC (te whakakore i te paoro) te nuinga o te painga ki tera taha o te korerorero.
