Kaikōrero PA me te Kaikōrero Pū: Ngā Rerekētanga Matua
I roto i te umanga oro arumoni me te umanga whakamōhiotanga papatipu, he maha ngā wā ka raru te hunga e whakamahi ana i ngā kupu e pā ana ki ngā whakawhiti oro. Ko te kupu "kaikōrero PA" (Kaikōrero mō te Kōrero ā-Iwi) e whakamahia pinepinetia ana hei tohu whānui mō tētahi kaikorero e hono ana ki tētahi pūnaha oro tohatoha. Ahakoa e whakamahia ana e te umanga oro ngaio whānui te "kaikorero PA" hei whakaahua i tētahi whare whakapakari oro—tae atu ki ngā taputapu kōnohete e utaina ana ki te haona—i roto i te oro tohatoha arumoni, e pā ana ki tētahi kaikorero e whiti tika ana. He mea nui te mārama ki te rerekētanga i waenga i tētahi kaikorero PA e whiti tika ana me tētahi kaikorero haona mō ngā kaiwhakauru AV, ngā tohunga oro, me ngā kaiwhakahaere whare e mahi ana ki te hoahoa i ngā pūnaha e tutuki ana i te māramatanga motuhake (e aro ana ki tētahi Taupū Tuku Kōrero o >0.50), te kapinga, me ngā whakaritenga taiao.
Ko te rerekētanga matua i waenga i ēnei hangarau e rua kei roto i tā rātou tikanga whakawhiti hiko-oro me te hononga oro ki te hau e karapoti ana. Ko te kaikorero PA paerewa e whakamahi ana i te taraiwa kōni neke-koi e mau ana i roto i te whare hiri, i te whare pupuri rānei. Ka tukuna tika te oro e tēnei hoahoa ki te taiao, me te whakatairanga i te urupare auau whānui (mai i te 60 Hz ki te 20,000 Hz) me te taurite oro tūturu. He rerekē, ka whakamahia e te kaikorero tetere he taraiwa pēhi motuhake e honoa ana ki te arataki ngaru oro mura (te tetere). Ka mahi tēnei whirihoranga hei whakawhiti oro, e whakataurite ana i te aukati miihini teitei o te diaphragm o te taraiwa ki te aukati oro iti o te hau e karapoti ana. Ka whakanuia e tēnei te pai o te hiko-oro, ahakoa he iti te auau (he maha ngā wā ka heke iho i raro i te 300 Hz).
Mō ngā kaihoahoa pūnaha, ko te whiriwhiri i waenga i te kaikorero PA me te kaikorero tenetene he tatau i runga i ngā here ā-tinana o te wāhi whakatakoto. Ko te whakatau e whakawhirinaki ana ki te Taumata Pēhanga Oro (SPL) e hiahiatia ana, te papa haruru taiao, te tawhiti maka e hiahiatia ana, me te ihirangi matua e whakapaohotia ana - ahakoa he puoro papamuri whānuitanga katoa, he whārangi reo nui, he oro whakawātea ohorere rānei.
Te kaupapa matua me te kapinga oro
Ko te kaupapa matua o tētahi kaikorero PA tuku iho ko te tuku oro tino pono puta noa i tētahi whānuitanga auau whānui. Mā tēnei ka taea e ia te whakaputa anō i ngā momo puoro kua tuhia me te oro tūturu o te reo tangata. Nā te mea ka whakawhirinaki ngā kaikorero PA paerewa ki ngā koeko e whiti tika ana, he whānui, he kōniko hoki te whānuitanga o te oro, ā, he maha ngā wā ka horapa te oro i ngā koki i waenga i te 90° me te 120°. He tino whai hua tēnei horapa whānui mō te kapi i tētahi wāhi ki te oro ōrite, mena ka tika te whakahaere i te teitei o te tuanui (8 ki te 14 putu te pai) me ngā whakaata oro.
I tetahi atu taha, he mea hanga ngā kaikorero oro kia tino kitea te pūoro me te uruhanga. Ko tā rātou mahi matua he tuku oro whaiti, tino mārama ki ngā tawhiti roa, ki ngā taiao rānei he nui te haruru o te taiao. Ko te mura o te oro e tohu ana i te tauira marara, he whaiti ake, he tino whakahaeretia hoki—he maha ngā wā ka herea ki te 60° mā te 40°, ka kikī ake rānei, ka puta he tauwehenga Ārahi (Q) teitei o te 10 ki te 15. Mā tēnei aronga arotahi ka whakatōtō te kaha oro ki roto i tētahi hihi motuhake, ka whakaiti i te maringi oro ki ngā wāhi kāore e hiahiatia, ka whakaiti hoki i te whakaoho o ngā mara whakaata i roto i ngā taiao whakaata nui.
Ngā tono wāhitau tūmatanui me ngā tono whārangi noa
I roto i te whakamahinga mahi, ko ngā kaikorero PA paerewa te whiringa taunoa mō ngā taiao e whai ana i te kounga oro, te whakaurunga ataahua, me te kapinga ōrite o te oro iti ki te reo waenga (te tikanga 70 ki te 85 dB) hei whāinga matua. Ka whakamahia whānuitia e ngā kaiwhakauru ngā kaikorero PA e mau ana ki te mata, ki te whakairi, me te tuanui i roto i ngā toa hokohoko, ngā rūma poari umanga, ngā wāhi manaaki manuhiri, me ngā whare mātauranga. I roto i ēnei tautuhinga, me whakawhiti pai te pūnaha i waenga i te whakarato puoro papamuri kore e kitea (BGM) me te reo ā-rohe mārama, tūturu te tangi.
He maha ngā wā ka tohua ngā kaikorero haona mō ngā mahi ahumahi, o waho, me ngā mahi haumaru ora, ina nui ake te putanga oro mata me te oranga i te pono o te puoro. He paerewa ēnei i roto i ngā papa reriwe, ngā papa hanga, ngā papa tākaro hākinakina, me ngā pūnaha whakatūpato ohorere ā-tāone. I roto i tētahi wheketere hanga me te papa haruru taiao o te 85 ki te 90 dB(A), ka toremi te kaikorero PA paerewa, ka pakaru rānei ki te ngana ki te whakakore i te haruru. Heoi, ka taea e te kaikorero haona te whakaputa ngāwari i te putanga tihi 105 ki te 115 dB(A) e tika ana hei whakatutuki i te ōwehenga tohu-ki-haruru +10 dB ki te +15 dB e hiahiatia ana mō te māramatanga.whārangi wharangi ohorereHe mea tika kia mōhiotia kāore tēnei wehewehenga o roto/o waho i te tino tūpono; he maha ngā wā ka whakamahia ngā kaikorero PA ātete-huarere tika ki waho mō te oro pono teitei, ko ngā kaikorero tetere ia ka whakamahia i roto i ngā wāhi haruru, ana hoki pērā i ngā papa hukapapa, i ngā whare putunga rānei.
He aha te Kaikōrero PA
I roto i te horopaki o te oro tohatoha arumoni, e pā ana te kaikorero PA ki tētahi kaikorero e whiti tika ana i hangaia hei whakaputa i te whānuitanga o ngā auau oro mō te whakapaoho whānui. Ko ngā kaikorero PA arumoni kua tāutahia he mea hanga mō te mahi tonu i roto i ngā whatunga tohatoha ngaohiko pumau 70V, 100V rānei. Mā tēnei ka taea te hono i ngā tekau, tae atu ki ngā rau o ngā kaikorero puta noa i tētahi whare nui mā te whakamahi i te waea iti-ira (16 ki te 18 AWG te nuinga), ka whakakore i te ngaronga tohu nui e puta mai ana me te waea iti-ātete paerewa (8-ohm) i runga i ngā taura neke atu i te 100 ki te 200 putu.
Ko te hanganga ā-tinana o tētahi kaikorero PA arumoni he mea hanga ki te kirihou ABS i werohia, ki te papa muka matotoru-waenga (MDF), ki te maitai rānei. I roto i te pouaka, ka whakanohoia tētahi, neke atu rānei o ngā whakawhiti koiri neke ki te ārai o mua. Ka ārai te pouaka i ngā ngaru oro i waho o te āhua i hangaia e te tuara o te koeko kaikorero kei takai, kei whakakore hoki i ngā ngaru oro i hangaia e te mua, he mea nui mō te whakaputa anō i ngā auau iti me ngā auau waenga-iti.
Hei hono atu ki ngā whatunga oro tohatoha, kua whakauruhia ngā kaikorero PA arumoni ki ngā whakawhiti hiko e hono ana i te raina ki raro. He maha ngā taputapu matua o ēnei whakawhiti hiko (hei tauira, 1.5W, 3W, 6W, 15W, 30W), e āhei ai te kaiwhakauru pūnaha ki te whakarite takitahi i te kaha e tangohia ana e ia kaikorero. He mea nui tēnei āheinga mō te whakataurite i ngā taumata SPL puta noa i ngā rohe rerekē o te whare.
Te whakaputa anō a ngā kaikōrero PA i te kōrero me te puoro
Hei whakatutuki i tētahi urupare auau whānui, papatahi hoki, he maha ngā wā ka whakamahia e ngā kaikorero PA arumoni tētahi hoahoa oro rua-ara. Mā tēnei whirihoranga ka wehea te tohu oro kia rua ngā roopu auau motuhake mā te whakamahi i tētahi whatunga whakawhiti ā-roto (e whakawhiti ana i waenga i te 2.5 kHz me te 3.5 kHz). Ka tukuna ngā auau iti me ngā auau waenga-whānui ki tētahi kōne woofer nui ake (e 4 ki te 8 inihi te whānui), ko ngā auau teitei ia ka tukuna ki tētahi tweeter iti ake (e 0.75 ki te 1 inihi te whānui).
Mā te wehewehe i te mahi i waenga i ngā whakawhiti oro kua arotauhia mō ō rātou awhe auau, ka taea e ngā kaikorero PA ara-rua te whakaputa anō i ngā oro papaku hohonu e hiahiatia ana mō te puoro o mua me ngā oro oro matua e tika ana mō te mārama o te reo. Mā te whatunga whakawhiti ka pai te whakawhiti i waenga i ngā taraiwa, ka mau tonu te oro reo tūturu e ārai ana i te ngenge o te kaiwhakarongo i te wā e purei roa ana.
Ngā whakamahinga o roto me ngā whakamahinga arumoni tino pai
Nā te mea he tino pai ki a rātou te whakaputa i te whānuitanga o te auau katoa me te horapa whānui, he pai rawa ngā kaikorero PA mō ngā taiao arumoni he iti te haruru o te taiao (i raro iho i te 65 ki te 70 dB(A)). He nui te whakawhirinaki o ngā taiao hokohoko ki ēnei kaikorero hei waihanga i tētahi āhuarangi waitohu rumaki mā te puoro papamuri tino pono, me te whakamahi anō hoki mō ngā whārangi a ngā kaimahi. Ka whakamahia e ngā taiao umanga ngā kaikorero PA kei runga i te tuanui i roto i ngā whare tomokanga me ngā ara raro hei whakarato i tētahi wheako whakarongo maeneene.
Hei tāpiri atu ki tēnā, kua hangaia ngā kaikorero PA me te whai whakaaro ki te whakaurunga hoahoanga. Ka tukuna ēnei waeine e ngā kaihanga i roto i ngā whakatakotoranga tuanui iti-kōtaha, ngā porowhita tautau mō ngā tuanui hoahoanga tuwhera, me ngā kāpata whakairi mata maeneene. Ahakoa e kiia ana he otinga ā-roto, he maha ngā kaikorero PA hou he wāhanga huarere, e pai ai mō ngā taupee kai o waho me ngā pāka kaupapa kei reira tonu te pono o te oro hei kaupapa matua.
He aha te Kaikōrero Pūoro
He pūwhakawhiti hiko-oro motuhake te pūorooro haona i hangaia hei whakanui ake i te putanga oro, te whakaata, me te whai huatanga. Engari i te whakawhirinaki ki tētahi koeko nui, e whiti tika ana, ka whakamahia e te pūorooro haona tētahi diaphragm iti, pakari kei roto i tētahi taraiwa pēhi. Ka honoa ā-mīhini tēnei taraiwa ki te korokoro whaiti o tētahi arataki ngaru oro (he maha ngā wā he 1-inihi, he 2-inihi rānei te whānui putanga)—ko te hanganga haona mura e tapaina ai te taputapu.
Ko te āhuatanga matua o te pūoro tetere ko tōna kaha ki te whakataurite i te aukati oro. Ka whakaputahia e te taraiwa kōpeketanga ngā ngaru oro i te pēhanga tino teitei i roto i te korokoro whaiti o te tetere. I te haere o ngā ngaru oro ki waho mā roto i te mura e whānui haere ana, ka heke te pēhanga i te mea ka piki ake te tere o te matūriki, ka ōrite pai ki te aukati o te hau tuwhera. Ka āraihia e tēnei mahi rite ki te whakawhiti i ngā whakaata oro nui, ka taea ai te tuku i te nuinga o te kaha oro ki mua.
Nā te kaha o tēnei mahi, he iti ake te mana hiko e hiahiatia ana mō ngā kaikorero haona hei whakaputa i ngā taumata pēhanga oro teitei ki te whakataurite ki ngā kaikorero PA tuku iho. He maha ngā wā ka taea e te kaikorero haona noa te whakaputa i te 105 dB ki te 110 dB o te putanga mai i te kotahi watt o te mana whakakaha i inehia i te mita kotahi, ki te whakataurite ki te 85 ki te 90 dB noa iho mō te kaikorero kōne paerewa. Heoi, ko te auau iti rawa ka taea e te haona te whakaputa pai ka whakatauhia e te porowhita o tōna waha. Nō reira, kāore e taea e te nuinga o ngā haona paging arumoni te whakaputa i ngā auau pāoro iti, ka hua ake he kōtaha oro e aro ana ki ngā auau waenga me ngā auau teitei (te tikanga 300 Hz ki te 8,000 Hz).
Te whakanui ake i te pūwhakaata i te utaina o te haona
Ka tino whakarerekē te utaina o te pū i te aronga o te ngaru oro. Ahakoa ka ringihia e te taraiwa kōne tahanga te kaha oro ki ngā taha katoa, ka herea e ngā pakitara pakari o te arataki ngaru oro te ngaru oro, ka akiakihia ki roto i tētahi tauira hipoki motuhake, ka taea te matapae. Mā te aukati i te kaha oro kei horapa poutū, taha rānei ki ngā wāhi tata, ka whakaemihia e te pū te kaha oro katoa e wātea ana i mua tonu i tōna tuaka matua.
Mā tēnei kukū o te pūngao ka taea e ngā kaikorero te whakatutuki i ngā tawhiti whiu nui, e whakaatu ana i te reo mārama mai i te 50 ki te 150 mita, neke atu rānei. Mā te hoahoa ā-tinana ka noho pūmau tonu ngā ngaru oro auau-teitei, ka taea ai e ngā auau whakapuakitanga nui o te reo tangata (2 kHz ki te 4 kHz) te whana i roto i ngā taiao kikī, haruru, he pai ake i te pūtake oro whānui-marara.
Ngā whakamahinga o waho me ngā whakamahinga ahumahi tino pai
Nā ngā āhuatanga oro o ngā pūoro tetere, he mea whiriwhiri nui ēnei mō ngā taiao o waho, ā,ngā tono ahumahi taumahaI ngā wāhi pēnei i ngā teihana tereina, ngā tauranga kaipuke, me ngā papa rakau, he mea nui te tuku i tētahi panuitanga ki tawhiti. Ka tātarihia e te roopu auau whaiti o te kaikorero te haruru auau iti o ngā miihini tīhiera me ngā mīhini taumaha, kia mōhio ai kei te noho te tohu wharangi reo i tētahi wāhi motuhake, ka rangona i roto i te whānuitanga oro.
Hei tāpiritanga, he pakari ngā kaikorero haona. Nā te mea kei roto i te anga taumaha o te taraiwa kōpeketanga te diaphragm ngawari, ka tiakina mai i ngā huarere. Ko te nuinga o ngā kaikorero haona arumoni he mea hanga mai i te kirihou ABS ātete-UV, te konumohe miro, te muka karāhe rānei, e ngāwari ai te whakatutuki i ngā whakatauranga IP66, IP67 rānei, ā, e mahi ana i roto i ngā rohe pāmahana tino kino (hei tauira, -40°C ki te +60°C). Nā tēnei ka pai mō ngā taiao moana, ngā whakaurunga huarere tino kino, mengā whare hanga morearea.
Whakataurite Whakatakotoranga
Ina aromatawaihia ngā kaikorero PA me ngā kaikorero tetere mō te hoahoa oro arumoni, ka whakawhirinaki ngā whakauru AV ki tētahi huinga paerewa o ngā whakatakotoranga hiko-oro hei matapae i te mahi a te pūnaha. Ka whakamahia e te pūmanawa whakatauira oro, pērā i te EASE (Enhanced Acoustic Simulator for Engineers), ēnei whakatakotoranga hei whakaputa mahere wera o ngā taumata pēhanga oro me ngā kaute māramatanga puta noa i tētahi tauira 3D mamati o te wāhi.
Ko ngā inenga tino hira ko te urupare auau, te aro (SPL i te 1W/1m), te koki kapinga ingoa, me te Taupū Tuku Kōrero (STI) e hua ake ana. Hei tāpiri, ko ngā whakatakotoranga ā-tinana me ā-hiko e whakatau ana i te oranga o te taputapu me te utu katoa o te mana whakahaere i roto i tōna roanga mahi.
| Ahu Whakatakotoranga | Pūoro PA Paerewa (Mata/Taumata) | Kaikōrero Pū (Whārangi/Ahumahi) |
|---|---|---|
| Urupare Auau | 60 Hz – 20,000 Hz (Awhe Katoa) | 250 Hz – 10,000 Hz (Rōpū Reo) |
| Te aro (1W/1m) | 85 dB ki te 95 dB | 105 dB ki te 115 dB |
| Koki Taupoki Ingoa | 90° ki te 120° (Koniko/Whānui) | 40° ki te 60° (Teitei te Aronga) |
| Ngā Taputapu Hiko Noa | 1.5W, 3W, 6W, 15W, 30W | 7.5W, 15W, 30W, 60W, 100W |
| Te Whakamahinga Matua | BGM, FGM, Whārangi o roto | Pānui mō te Ohotata, i Waho |
| Whakatauranga IP Noa | IP20 ki te IP44 (Rohe/Taupokina) | IP66 ki te IP67 (Huarere Kino) |
| Rauemi Āpiti | MDF, ABS Māmā, Ngā ipu-muri maitai | ABS taumaha, Konumohe, Karāhe muka |
Te urupare auau, te SPL, me te koki kapinga
E ai ki te whakatauritenga whakatakotoranga, mā te urupare auau whānui o te kaikorero PA paerewa ka taea te whakaputa puoro whai kiko, engari ko tēnei āheinga whānuitanga-katoa me nui ake te mana whakakaha (he maha ngā wā 15W ki te 30W mō ia kaikorero) kia tutuki ai ngā SPL teitei. Ko te tikanga o tōna koki kapinga whānui ka tere ake te memeha o te oro i tawhiti, e whai ana i te ture tapawhā whakamuri (-6 dB mō ia takirua o te tawhiti).
He rerekē rawa ngā ōwehenga pāngarau o ngā kaikorero pūoro. He tino pai te hononga o tā rātou urupare auau poto ki te whānuitanga o te reo tangata. Nā te mea kāore te kaha e moumouhia ana ki te whakaputa i ngā auau iti e hiahia ana ki te kaha, he tino teitei te aro. Me te koki hipoki piri, ka tukuna tika tēnei SPL ā-rohe ki te wāhi e hiahiatia ana me te iti o te kukume kaha (he maha ngā wā ka tutuki ngā SPL whainga me te 2W ki te 5W noa iho o te kaha pato).
Te mārama, te tawhiti whiu, me te kounga puoro
Ka inehia te māramatanga o te oro arumoni mā te whakamahi i te Speech Transmission Index (STI), he tauine mai i te 0.0 ki te 1.0. Ko ngā waehere haumaru ora (pēnei i te NFPA 72, EN 54-24 rānei) e hiahia ana kia iti rawa te STI o te 0.45 ki te 0.50 mō ngā whakaoho reo ohorere. I roto i ngā tawhiti poto i roto i ngā rūma e rongoatia ana te oro, ka eke ngā kaikorero PA ki ngā kaute STI pai rawa atu (he maha ngā wā >0.60). Heoi, i roto i ngā wāhi nui, e pāorooro ana, ka whakaoho te horapa whānui o te kaikorero PA i te mara pāorooro o te rūma, ka puta he pāorooro taupatupatu e tino whakaiti ana i te STI.
He tino pai ngā kaikorero oro ki te pupuri i ngā kaute STI teitei i ngā tawhiti maka roa i roto i ngā taiao oro kino. Mā te whakawhāiti i te kaha oro ki tētahi hihi whaiti, ka whakaitihia e te kaikorero oro ngā whakaata mai i ngā tuanui me ngā pakitara taha. Heoi, nā tēnei āhua oro anō ka kore e pai ngā kaikorero oro mō te purei puoro kounga teitei, nā te mea ko te kore o te pāoro me te whakanui rawa i te awhe waenga ka hua ake te ngenge o te kaiwhakarongo mēnā ka whakamahia mō te puoro papamuri tonu.
Te utu, te pakari, me te uara o te huringa ora
Mai i te tirohanga whakapaunga whakapaipai (CAPEX), he iti ake te utu o ngā kaikorero PA arumoni paerewa mō ia waeine (te tikanga $40 ki te $150 USD) i ngā kaikorero haona ahumahi taumaha. Heoi, ko te uara o tō rātou oranga e whakawhirinaki ana ki te taiao; ko te whakatinanatanga o ngā kaikorero PA paerewa o roto i ngā wāhi haumākū nui, o waho rānei, me whakakapi pinepine (he maha ngā wā ka pakaru i roto i te 2 ki te 3 tau).
He nui ake te haumitanga tuatahi mō ngā kaikorero haona ($100 ki te $400+ USD) engari he tino pai te roa me te uara o te huringa ora i roto i ngā taiao uaua, he maha ngā wā e whakamanamana ana ki te roanga mahi 15 ki te 20 tau. He tino ātete ngā rauemi pēnei i te polycarbonate UV-stabilized me te konumohe miro ki te pirau taiao. Hei tāpiri, he maha ngā taraiwa kōpeketanga kounga teitei kei a rātou ngā diaphragm koiri reo ka taea te whakakapi i te mara, e āhei ai ngā tohunga hangarau ki te whakatika i te taraiwa pupuhi mō te iti o te utu o te kaikorero hou.
Me pēhea te whiriwhiri i te kaikorero tika
He tukanga maha-mātauranga te whiriwhiri i te hangarau pūorooro tika e hiahia ana kia aromatawaihia te oro o te whare, ngā here hangarau hiko, me ngā ture tutuki haumaru-ora. Me hanga e ngā kaiwhakauru he huinga tohatoha e whakarato ana i te kapinga ōrite, e tutuki ana i te ōwehenga tohu-ki-haruru e hiahiatia ana (ko te whāinga paerewa he +10 dB ki te +15 dB i runga ake i te haruru taiao), ā, ka whakauru haumaru ki roto i te hanganga o nāianei o te whare.
Me tīmata te wāhanga hoahoa me te rangahau hōhonu i te wāhi, te tātari rānei i ngā mahere hoahoa. E tino taunakihia ana te whakamahi i te tauira oro mō ngā wāhi uaua hei matapae i te taunekeneke a te aronga o te haona, te horapa whānui rānei o te kaikorero PA ki ngā rohe ā-tinana o te rūma.
Whakatauritehia te momo kaikorero ki te taiao me te hunga whakarongo
Ko te tuatahi o ngā whakatau matua ko te whakataurite i te whakawhiti ki te haruru o te taiao me te mahi matua a te hunga whakarongo. Me ine e ngā kaiwhakauru te toharite me te taumata haruru o te taiao teitei (i roto i te dB-A) o te wāhi.
| Taiao | Haruru Āhua Noa (dB-A) | Momo Kaikōrero e Manakohia ana | Whāinga Whārangi SPL (dB-A) |
|---|---|---|---|
| Tari Pakihi / Whare Pukapuka | 40 dB – 50 dB | Tuanui/Mata PA | 55 dB – 65 dB |
| Toa Hokohoko / Wharekai | 60 dB – 70 dB | Tuanui/Tauira PA | 75 dB – 85 dB |
| Whare Waka ā-Rohe | 75 dB – 85 dB | Te Pū Aronga | 90 dB – 100 dB |
| Te Papa Hanga / Te Papa Rerewē | 85 dB – 95+ dB | Te Pū Putanga-Teitei | 100 dB – 110+ dB |
Mena he papa hokohoko te taiao me te taumata haruru o te taiao o te 65 dB, ka taea e te whatunga o ngā kaikorero PA kei runga i te tuanui te whakarato i te oro mārama, me te pupuri tonu i te urupare auau whānui e hiahiatia ana mō te puoro papamuri pono-teitei.
I tetahi atu taha, ki te mea he whare waka tāone te taiao me te taumata haruru o te taiao o te 85 dB nā te haere o ngā waka, tera pea ka kore e taea e te kaikorero PA paerewa te tuku karere mārama. Me whakamahi te pūnaha i ngā kaikorero haona e anga ana ki raro i ngā ara taraiwa hei tapahi i te haruru o te miihini me te whakahaere i te kaha oro, kia kore ai e pekepeke tonu mai i ngā papa raima. I tēnei horopaki, me whakarongo noa te hunga whakarongo ki ngā tohutohu whakawātea, ki ngā whakatūpato haumaru rānei.
Tirohia te mana, te aukati, te whakatauranga huarere,
me ngā whakaritenga whakamau hei whakarite i te pono mō te wā roa. Kia tutuki ngā hiahia oro, manatokohia kei te rite te kaikorero kua whiriwhiria ki ngā kaha mana o te whakakaha (kia mau tonu te 20% te iti rawa o te tawhē o te pane) me te hanganga ārai o te pūnaha (hei tauira, 70V/100V vs. 8-ohm). Hei tāpiri, arotakehia marietia te whakatauranga IP (Ingress Protection). Ahakoa he tino pai ngā kaikorero haona i roto i ngā āhuatanga uaua, he maha ngā kaihanga e tuku ana i ngā kaikorero PA e tuku tika ana i te hihi tika, he ātete ki te huarere, he IP55 te whakatauranga mō ngā taiao o waho. I tetahi atu taha, he maha ngā wā ka whakatakotoria ngā kaikorero haona ki roto i ngā wāhi haruru, he wāhi haruru pērā i ngā whare hanga. Hei whakamutunga, ko te whiriwhiri i waenga i te kaikorero PA me te kaikorero haona ka heke ki te whakataurite i te pono o te oro ki te putanga mata me te ahunga. Mā te aromatawai i te haruru taiao, te tawhiti maka e hiahiatia ana, me te ihirangi oro matua, ka taea e ngā kaihoahoa pūnaha te whakamahi i te hangarau tika mō te whakawhitiwhiti kōrero mārama, pono hoki.
Ngā Whakaaro Matua
- Whakamahia ngā kaikōrero PA e whiti tika ana ina hiahia koe ki te kapinga whānui, taiao mō te reo me te puoro puta noa i te awhe auau whānui, i te nuinga o te wā i waenga i te 60 Hz ki te 20,000 Hz.
- Whakamahia ngā kaikōrero tetere ina ko te mea nui ko te whakaputa reo tino whai hua mai i tawhiti, inā koa i ngā taiao haruru, i waho, i ngā taiao ahumahi rānei.
- Whakamaherehia te kapinga mā te marara: he maha ngā kaikorero PA e hora ana i te oro huri noa i te 90° ki te 120°, ko ngā kaikorero tetere ka arotahi pea i te putanga ki te 60° mā te 40°, kikī ake rānei.
- Mō ngā tono whakamōhiotanga ohorere me te papatipu, hoahoahia kia rite ki ngā whāinga mārama pērā i te STI i runga ake i te 0.50, kaua ko te haruru anake.
- Kaua e whakamahi i ngā kaikorero tetere hei kaikorero puoro whānuitanga-katoa nā te mea he maha ngā tauira e ngaro ana te putanga auau iti i raro iho i te 300 Hz.
- Tātaitia te momo kaikorero ki ngā āhuatanga o te papa, tae atu ki te haruru o te taiao, te tawhiti o te whiu, te teitei o te tuanui, te pānga o te huarere, me ngā whakaritenga mō ngā wāhi morearea.
Ngā Pātai Auau
He rite tonu te kaikorero PA ki te kaikorero tetere?
Kāore rawa. He whānui te kupu o te pūoro PA, engari i roto i te oro tohatoha, ko tōna tikanga he pūoro e whiti tika ana. Ka whakamahia e te pūoro tetere he taraiwa kōpeketanga me te tetere mura hei whakaputa i te oro ki tawhiti atu, ki te pai ake hoki.
Āhea ahau me whiriwhiri ai i tētahi kaikorero tetere?
Kōwhiria he pūoro tetere mō te whakarongo ki ngā whārangi tawhiti, mō ngā whakatūpato ohorere, mō ngā wāhi o waho, mō ngā wāhi ahumahi haruru rānei, ina nui ake te hiranga o te māramatanga o te kōrero me te whakaata i te kounga o te puoro.
Āhea te wā e pai ake ai te kaikorero PA paerewa?
He pai ake te whakamahi i te pūoro PA paerewa mō te whānuitanga o te oro, ā, he pai ake te horapa o te oro, inā koa mēnā e hiahiatia ana he puoro, he pānuitanga, he whakaputa reo taurite i roto i ngā tari, i ngā puni, i ngā toa, i ngā whare o roto rānei.
He aha i kitea whānuitia ai ngā kaikōrero tetere i roto i ngā taiao ahumahi?
He pai te whai hua o ngā pūorooro, he aronga tika, ā, ka taea te whakakore i te haruru nui o te taiao. Nā tēnei ka whai hua rātou mō te keri maina, te hinu me te hau, te kawe waka, te hanga whare, te moana, me ētahi atu taiao kino.
He pai te whakaputa a ngā kaikōrero tetere i te reo pāoro?
Kāore i te nuinga o te wā. He pai ake ngā kaikorero oro mō te whakaputa reo, ā, he maha ngā wā ka tere te heke iho i raro iho i te 300 Hz, engari he maha ngā kaikorero PA ka taea te hipoki i te whānuitanga whānui, i te nuinga o te wā i waenganui i te 60 Hz ki te 20,000 Hz.
