Rangahau mō te Whakaiti Haruru o ngā Pūwhakakoi Auau-Rērere mā te Whakamahi i te Hiko-Whero Basalt
I. Te Papamuri me te Hiranga o te Rangahau
Kua noho te parahanga haruru o te taiao hei take nui e pā ana ki te hauora me te kounga o te oranga o te tangata, ā, ko ngā taputapu ahumahi (hei tauira, ngā pūwero auau-rerekē) te take nui. Ko ngā rauemi tuku iho e mimiti haruru ana (hei tauira, te muka miro) he iti noa te mahi i roto i ngā awhe auau teitei, ā, he ngāwari ki ngā āhuatanga taiao pēnei i te pāmahana. muka pātarati, he rauemi kore-waro mahi-teitei me te hanganga pūwero me ngā āhuatanga oro pai rawa atu, kua puta ake hei huarahi pai mō ngā tono whakahaere haruru.
II. Ngā Āhuatanga me te Hanganga o muka pātarati
1. Ngā Painga Rauemi
Ko te muka basalt, tētahi o ngā muka matua e whā o Haina, e whakarei ake ana i te mimiti oro mā te huri i ngā wiri o te hau i roto i ōna pūwero hei pūngao wera. Nā te matotoru me te hanganga kua whakapaitia, he pai ake te whai huatanga i te muka miro mō te mimiti haruru whānui.
2. Tukanga Hanga
I whakawhanakehia e ngā kairangahau o Te Whare Wānanga o Qingdao tētahi hiato whakarewa mā te whakaranu i ngā muka pātarati me ngā muka miro. Mā te arotau i ngā ōwehenga me ngā tawhā tukatuka, i tutuki i te hiato te ngāwari me te mahi oro teitei. I whakaatuhia e ngā whakamātautau tōna whakaiti haruru pai rawa atu i ngā auau teitei (85 Hz) ki te whakaritea ki ngā auau iti (45 Hz), me te whai huatanga nui ake i ngā taiao pāmahana iti.
III. Te Hoahoa Whakamātautau me te Tātari Whakaiti Haruru
1. Ngā Tikanga Whakamātautau
I arotakehia e ngā whakamātautau ngā taumata haruru i raro i ngā āhuatanga whakahaere rerekē (pāmahana, auau) o tētahi pūwero auau-rerekē, e kapi ana i ngā roopu auau iti (45 Hz), waenga (65 Hz), me te teitei (85 Hz). I whakaritea te mahi i waenga i te muka rino basalt me te miro rino tikanga.
2. Ngā Hua Matua
Te Hiranga o te Auautanga-Teitei: Te muka rino basalti tutuki i te tauwehenga mimiti oro o te 0.85–0.95 i ngā auau teitei, e tata ana ki te mahi a te phenolic muka karāhe i te mea i rongohia.
Te Whakawhirinakitanga ki te Pāmahana: Ka pai ake tōna kaha ki te pehi haruru i ngā pāmahana iti iho, engari ka pirau ngā rauemi tuku iho i ngā pāmahana teitei.
Mahi Whānui: I whakapai ake te hiato basalt i te whakaiti haruru mā te ~20% ki te whakaritea ki te miro huruhuru i te auau kotahi, ā, i whakaiti pai i te haruru whānui mai i ngā wiri o te pūwero me te rere o te hau.
IV. Te Whakataurite ki ngā Hangarau Whakaiti Haruru Tuku Iho
1. Te Mahi Rauemi
Ahakoa he nui ngā tauwehenga mimiti o ngā rauemi tuku iho (hei tauira, te huruhuru karāhe) (0.90–0.99), ka pāngia rātou e te koroheketanga me ngā āwangawanga taiao. Ka rite te muka pātarati ki tā rātou mahi oro, ā, he pai ake te ātete ki te wera me te pai ki te taiao.
2. Ngā horopaki tono
He rerekē ki ngā otinga kore mahi (hei tauira, ngā ārai, ngā ārai haruru), ka taea te takai tika i te muka pātarati ki ngā pūwero, te whakauru rānei ki roto i ngā hanganga ārai oro, kia māmā ake ai te whakahou. Hei tauira, i roto i ngā pūnaha HVAC, ka whakaitihia te tuku haruru iti-auau mā roto i ngā paipa parahi ki roto i ngā wāhi o roto.
V. Ngā Tūmanako me ngā Wero
1. Ngā Taupānga Ahumahi me te Whare
He pai te whakamahi i te muka pātarati mō ngā pūwero ā-ahumahi, ngā waeine hauhautanga, me ētahi atu. I te whakakotahitanga me ngā ārai, ka taea te whakaiti i te haruru o te rohe wheketere ki raro iho i te 45 dB, e tutuki ai ngā paerewa taiao.
2. Te Arotau Hangarau
Whakarei i te Auautanga Iti: Ka taea e ngā hoahoa ranu (hei tauira, ngā hanganga hanawiti) te whakapai ake i te mimiti auautanga iti.
Te Whakaiti i ngā Utu: He mea nui te whakanui ake i te hanga hei whakaiti i ngā utu, nā te mea he nui tonu te utu o te muka o te papare.
VI. Whakamutunga
Ko ngā hiato muka-whao basalt, me ngā hanganga me ngā tukanga hanga kua arotauhia, e whakaatu ana i te kaha nui mō te whakahaere haruru auau-tiketike i roto i ngā pūwero auau-rerekē. Me arotahi ngā rangahau ā muri ake nei ki te pumau i raro i ngā āhuatanga mahi uaua me te mahi tahi me ētahi atu hangarau whakaiti haruru hei whakawhānui ake i te whakamahinga.
