I roto i te whakatinanatanga o te oro karapoti, he āhuatanga tō Dolby AC3 me DTS, arā, me maha ngā kaikorero i te wā e purei ana. Heoi, nā te utu me te wāhi, kāore i te nui ngā kaikorero o ētahi kaiwhakamahi, pērā i ngā kaiwhakamahi rorohiko rongorau. I tēnei wā, e hiahiatia ana he hangarau ka taea te tukatuka i ngā tohu maha-hongere me te purei anō i aua tohu i roto i ngā kaikorero e rua e whakarara ana, ā, ka rongo te tangata i te pānga oro karapoti. Koinei te hangarau oro karapoti mariko. Ko te ingoa Pākehā mō te oro karapoti mariko ko Virtual Surround, e kiia ana hoki ko Simulated Surround. Ka kiia tēnei hangarau e te tangata ko te hangarau oro karapoti kore paerewa.

Ko te pūnaha oro karapoti kore-paerewa e hangai ana ki te reo irirangi e rua-hongere, kāore he hongere me ngā kaikorero tāpiri. Ka tukatukahia te tohu mara oro e te ara iahiko, kātahi ka whakapaohotia, kia taea ai e te kaiwhakarongo te rongo kei te puta mai te oro i ngā taha maha, ā, ka puta he mara reo irirangi whakaata. Te uara o te oro karapoti mariko Ko te uara o te hangarau karapoti mariko ko te whakamahi i ngā kaikorero e rua hei whakaata i te pānga oro karapoti. Ahakoa kāore e taea te whakarite ki tētahi whare tapere kāinga tūturu, he pai te pānga i te tūranga whakarongo pai rawa atu. Ko tōna ngoikoretanga he kore e hototahi ki te whakarongo. He teitei ngā whakaritenga tūranga oro, nō reira he kōwhiringa pai te whakamahi i tēnei hangarau karapoti mariko ki ngā paneoro.

I ngā tau tata nei, kua tīmata te iwi ki te ako i te whakamahinga o ngā hongere iti rawa me ngā kaikorero iti rawa hei hanga oro-toru-ahu. Kāore tēnei pānga oro i te tino pono pērā i ngā hangarau oro karapoti pakeke pērā i a DOLBY. Heoi, nā te iti o te utu, kei te piki haere te whakamahinga o tēnei hangarau i roto i ngā whakakaha hiko, ngā pouaka whakaata, ngā oro motuka me ngā rongorau AV. Ka kiia tēnei hangarau he hangarau oro karapoti kore-paerewa. Ko te pūnaha oro karapoti kore-paerewa e hangai ana ki te reo irirangi-rua-hongere me te kore e tāpiri i ngā hongere me ngā kaikorero. Ka tukatukahia te tohu mara oro e te ara iahiko, kātahi ka whakapaohotia, kia taea ai e te kaiwhakarongo te rongo kei te puta mai te oro i ngā taha maha, ā, ka puta he mara oro whakaata.

Te Mātāpono Oro Karapoti Mariko Ko te mea nui ki te whakatutuki i te Oro Karapoti Dolby mariko ko te tukatuka mariko o te oro. He tohunga ki te tukatuka i ngā hongere oro karapoti i runga i te oro ā-tinana o te tangata me ngā mātāpono hinengaro-oro, e hanga ana i te whakaaro pohehe kei te puta mai te pūtake oro karapoti i muri, i te taha rānei o te kaiwhakarongo. He maha ngā pānga i runga i ngā mātāpono o te whakarongo tangata e whakamahia ana. Pānga rua-ira. I kitea e te tohunga ahupūngao Piritana a Rayleigh mā roto i ngā whakamātautau i te tau 1896 he rerekētanga wā (0.44-0.5 maikorohekona) ngā taringa tangata e rua, he rerekētanga kaha oro me ngā rerekētanga āhua mō ngā oro tika mai i te pūtake oro kotahi. Ka taea te whakatau i te aro o te taringa tangata ki te whakarongo i runga i ēnei mea iti. Ka taea e te rerekētanga te whakatau tika i te ahunga o te oro me te whakatau i te wāhi o te pūtake oro, engari ka taea anake te whakawhāiti ki te whakatau i te pūtake oro i te ahunga whakapae i mua, ā, kāore e taea te whakatau i te tūnga o te pūtake oro ā-wāhi toru-ahu.

Te pānga o te taringa. He mahi nui tā te taringa tangata i roto i te whakaata o ngā ngaru oro me te ahunga o ngā pūtake oro ā-wāhi. Mā tēnei pānga, ka taea te whakatau i te tūranga toru-ahu o te pūtake oro. Ngā pānga tātari auau o te taringa tangata. Ko te tikanga taunga oro o te taringa tangata e pā ana ki te auau oro. Ko te reo pāoro o te 20-200 Hz e kitea ana e te rerekētanga wāhanga, ko te awhe waenga o te 300-4000 Hz e kitea ana e te rerekētanga kaha o te oro, ā, ko te reo teitei e kitea ana e te rerekētanga wā. I runga i tēnei mātāpono, ka taea te tātari i ngā rerekētanga o te reo me ngā oro puoro i roto i te oro e pureitia ana, ā, ka taea te whakamahi i ngā maimoatanga rerekē hei whakanui ake i te kare ā-tāiawhio. Te mahi whakawhiti e pā ana ki te pane. Ka whakaputa te pūnaha whakarongo tangata i ngā whānuitanga rerekē mō ngā oro mai i ngā ahunga rerekē, ā, ka taea te whakaahua i tēnei āhuatanga whānuitanga e te mahi whakawhiti e pā ana ki te pane (HRT). Hei whakarāpopototanga, ko te tūranga ā-wāhi o te taringa tangata e toru ngā ahunga: whakapae, poutū, me mua me muri.

Ko te tūnga whakapae e whakawhirinaki ana ki ngā taringa, ko te tūnga poutū e whakawhirinaki ana ki te anga taringa, ā, ko te tūnga o mua, o muri hoki me te kitenga o te mara oro karapoti e whakawhirinaki ana ki te mahi HRTF. I runga i ēnei pānga, ka hangaia e te taiao Dolby mariko te āhua o te ngaru oro rite tonu ki te pūtake oro tuturu i te taringa tangata, ka taea ai e te roro tangata te whakaputa whakaahua oro e rite ana ki te aronga wāhi e rite ana.
