Ko te take o ngā "tohu teka" i roto iwhakanui tohu waea pūkoro he tino ānini mō te tini o ngā kaiwhakamahi. Me wehewehe tātou i tēnei raruraru hangarau i roto i tētahi huarahi e ngāwari ake ai te hono atu ki:
Whakaarohia kei te rapu koe i tētahi i roto i tētahi mākete haruru. He rite te whakanui tohu kounga iti ki tētahi kaumātua kāore e rongo pai ana—ahakoa kei te karanga ia "Kua whakanuia te oro!" mā te megaphone, ka mutu ka whakanuia e ia ngā haruru papamuri katoa (ngā oro tapahi, ngā reo tauhokohoko, me ētahi atu), ka uaua ake te whakarongo ki te reo tuturu e hiahiatia ana e koe. I tētahi atu taha, ka mahi te whakanui kounga teitei pērā i te miihini oro mohio, ka hopu tika, ka whakarei ake i te auau ūnga anake.
Ina koa, e toru ngā āhuatanga hangarau matua kei muri i tēnei āhuatanga:
1. Te Mōhio Tohu me te "Te Tika o te Taiaho"
Ka rite te mahi a te whakakaha tohu utu iti ki te tangata kite tata kāore he mōhiti—te pohehe i tētahi nekehanga hei tohu tika. Inaa, ka taea e ngā ngaru hikohiko auau-iti mai i ngā tāhū hau (0.1–10Hz) me te pokanoa 50Hz mai i ngā raina hiko te whakaoho i ngā hua teka. Ka whakamahia e ngā whakakaha tohu waea pūkoro utu nui ngā ara iahiko tātari maha-wāhanga, arā, he "matawai tapumati" mō ngā tohu, hei aukati i te haruru.
2. Te Tukanga "Tirotiro Atamai"
Ka whakamahia e te pūnaha pūkoro whakakaha whatunga tūturu te mana whakahaere whakarei urutau,He rite ki ngā pane whakarongo whakakore-haruru. Ina heke te ōwehenga tohu-ki-haruru ki raro iho i te 15dB, ka whakahohehia ngā rauropi DSP (Tukatuka Tohu Mamati) hei wehe i ngā tohu e taea ana te whakamahi—pēnei i te kaimaina koura e tātari ana i te onepu. Ngā taputapu whakakāhore? He rite tonu ki te whakakaha whakapōturi, e pupuhi ana i te pao i te taha o te tohu.
3. Te Parekura Kore e Kitea: Te Haumarutanga o te Irahiko
Ka turuturu ētahi whakakaha tohu waea pūkoro kāore i te whaimana i te irahiko hikohiko i te 10x te nui atu i te rohe haumaru—he rite ki te oumu ngaruiti kua pakaru te tatau. Ka whakamahia e ngā hua tika ngā pūnaha whakahaere porowhita-katia, e tuku ana i te pūngao pērā i te "pūwero tika" ki ngā pourewa waea pūkoro, me te piri tonu ki ngā paerewa haumaru tino pakari.
Whakakaha Tohu Waea Pūkoro Lintratek: Whakapai ake i tō Whatunga Waea Pūkoro me te Hangarau Matatau
Te Lintratekwhakanui tohu waea pūkoroe whakamahi ana i ngā wāhanga hou pēnei i a LowNgā Whakakaha Haruru (LNA)meNgā Whakakaha Mana (PA)hei whakarato i te mahi tino pai. Ka whakapai ake te LNA i te aro o te whiwhinga mā te whakaiti i te haruru o mua, ko te PA ia ka whakanui ake i te kaha o te tohu, kia mārama ai te hononga me te pumau. Mā te arotau i te raina, ka whakaitihia e te waea pūkoro whakakaha whatunga te whakapōturitanga o te tohu, ā, ka tātarihia pai te pokanoa (pēnei i te haruru hikohiko mai i ētahi atu roopu auau).
He mea hanga ki ngā tātari mahi-teitei te Lintratekwhakanui tohu waea pūkoroka whakakore i te pokanoa auau kore-taunga, ka whakarei ake i te parakore o te tohu. Ahakoa kei ngā wāhi tawhiti koe, kei ngā rohe tohu ngoikore rānei, ko tēneiwhakarei ake i te whatunga waea pūkoroka whakarite i te hononga pūkoro kounga teitei mō te whakawhitiwhiti kōrero maeneene.
Ngā Āhuatanga Matua:
1, Hangarau LNA me PA matatau mō ngā tohu kaha ake.
2、He tātari pokanoa tino pai mō ngā waeatanga mārama rawa.
3、Kua arotauhia te rārangi tika hei whakaiti i te hē.
4, Ngā tātari mahi-teitei mō te parakore o te tohu.
Kia mau tonu te hononga ki ngā wāhi katoa mā te whakamahi i te whakakaha tohu waea pūkoro pono a Lintratek—ko tō otinga whakakaha whatunga pūkoro tino pai rawa atu!
