Ukuqonda Isikhulumi Senkulumo Yomphakathi kanye Nesikhulumi se-PA Horn Sesikhulumi Sasefektri

• Ukukhetha izipikha zasefekthri kufanele kuqale ngokuzwakala kwenkulumo, hhayi nje kuphela amandla noma ukuphuma kwe-dB.
• Imiklamo yezipikha ze-PA horn ngokuvamile ingcono ezindaweni zezimboni ezisebenzisa ama-long throw, zangaphandle, kanye nezinomsindo omkhulu.
• Izindinganiso ezifana nokuthiIsiqondiso somsindo se-NISTfuthiI-ISO 7240-16ukusiza ukuqinisa izinqumo zesistimu ngezindinganiso ezilinganisekayo.
• Abathengi bephrojekthi kufanele baqinisekise isilinganiso se-IP, indlela yokufaka, ukuhambisana kwe-amplifier, kanye nokufinyelela ekulungisweni ngaphambi kokuthenga.

Izinhlelo zezikhulumi zenkulumo zomphakathi emafektri zahlulelwa ngokuzwakala kwenkulumo, hhayi nje ivolumu, ngoba abasebenzi badinga ukuzwa imiyalelo, imiyalezo yokuphuma, kanye nokucubungula izexwayiso kuwo wonke umsindo wemishini ongadlula u-85 dB(A) ezindaweni eziningi zezimboni, ngokusho kwe-Isiqondiso se-NIST mayelana nomsindo nokuvimbela ukulahlekelwa ukuzwaNgokwemibandela yokuthengwa kwangempela, iphakheji yesipikha sefektri kumele ilinganisele ukumbozwa, ukuqina, kanye nezindleko zokufakwa, futhi isipikha se-PA horn ngokuvamile siyisinqumo esisebenza kahle kakhulu lapho izilaleli zingaphandle, uphahla luphakeme, noma umugqa wokubona uvinjiwe. Uma iphrojekthi yakho ihlanganisa nezindawo zokuxhumana ezinobungozi njengeamadivayisi okuxhumana ezimbonini, izingcingo zezimboninomaocingo olungangenisi isimo sezulu, umthetho ofanayo uyasebenza: qondanisa idivayisi nendawo ezungezile kuqala, bese kuba nesabelomali.

Ukuqonda Isikhulumi Senkulumo Yomphakathi kanye Nesikhulumi se-PA Horn Ezinhlelweni Zesikhulumi Sefektri

Umehluko oyinhloko ukuthi isikhulumi senkulumo yomphakathi sihlose ukusatshalaliswa okubanzi, okulinganayo, kuyilapho isikhulumi se-PA horn sihlose ukuqopha okulawulwayo ngebanga.

Kuhlelo lwezipikha zasefektri, lo mehluko ubalulekile ngoba indawo ye-acoustic ayivami ukuthula noma ukufana. Izindawo zensimbi zidala ukubonakaliswa, imigqa yokuhambisa idala inkulumo efihliwe, kanti ama-forklift akhiqiza ukuphakama okungavamile okungafihla izimemezelo ezibalulekile. Ukuqondisa kwesipikha se-horn kusiza ukusunduza umsindo uye endaweni yokulalela esikhundleni sokuchitha amandla ezindleleni ezingasetshenziswanga.

Konjiniyela, umbuzo wangempela awusiwo othi “Yikuphi okunomsindo omkhulu?” kodwa “Yikuphi okunikeza inkulumo eqondakalayo endaweni yokulalela ekude kakhulu?” Lowo mbuzo uvame ukuphendulwa ngokuhlela ukumbozwa, hhayi ngenombolo eyodwa ye-decibel.

Kungani Ukukhetha Isikhulumi Sefektri Kuqala Ngokuqonda Inkulumo

Ukuzwakala kwenkulumo kuyisilinganiso esihlukanisa uhlelo lwesikhulumi esiwusizo sefektri kolukhulu nje.

Amafektri avame ukudinga ukubukezwa ukuze kushintshwe amashifu, imiyalelo yezimo eziphuthumayo, ukuhlanganiswa kokugcinwa, kanye nokuphuma. Uma abasebenzi bezwa ithoni kodwa bengaqondi amagama, uhlelo luhluleka injongo yalo yokusebenza. Yingakho ukwakheka kwezikhulumi zenkulumo yomphakathi kuhlotshaniswa nezilinganiso zokuzwakala njenge-STI, nokuthi kungani izinhlelo ze-alamu yezwi eziphuthumayo zilinganiswa ngaphansiI-ISO 7240-16ukulawula i-alamu yezwi kanye nemishini yokubonisa.

Umthetho osebenzayo ulula: uma umsindo wangemuva ukhuphuka, ukucaca kwenkulumo kwehla ngokushesha kunalokho abathengi abaningi abakulindele. Ngakho-ke ukuhlela umsindo wezimboni kudinga i-headroom, kodwa hhayi umsindo omkhulu odala ukukhathala noma ukunyakaza.

Uma Isikhulumi se-PA Horn Singcono Kungcono Kunoma Isiphi Isipikha Sasefektri

Isipikha se-PA horn ngokuvamile siyindlela engcono uma indawo okuqondiswe kuyo ivulekile, inomsindo, noma inkulu ngokomzimba.

Izindawo zokulayisha, izindawo zenqubo yangaphandle, amayadi okuhambisa izinto, izindawo zokugcwalisa uphethiloli, kanye nemizila yokusetshenziswa ngokuvamile kudinga iphethini ye-acoustic egxile enganqoba umoya, umsindo womshini, kanye nokulahlekelwa yibanga. Izipikha ze-horn nazo ziyathandwa uma kutholakala izindawo ezimbalwa zokufaka, ngoba iyunithi eyodwa eqondiswe kahle ivame ukuthatha indawo yezipikha ezincane eziningi.

Inkinga ukuthi izikhulumi ze-horn zingazwakala zingavamile uma ziseduze uma ziqhutshwa kakhulu noma ziqondiswe kabi. Yingakho amaqembu ephrojekthi kufanele aphathe ukukhetha i-horn njengomsebenzi wobunjiniyela, hhayi ukuthenga ikhathalogi.

1. Linganisa umsindo ozungezile ezindaweni zokulalela ezihlosiwe.
2. Chaza indawo edingekayo yokumboza inkulumo noma i-alamu.
3. Khetha amandla ophondo, i-angle yogongolo, kanye nokuphakama kokumisa.
4. Qinisekisa ukuhambisana kwesilawuli kanye ne-amplifier.
5. Hlola ukuzwakala ngemva kokufakwa, hhayi nje kuphela izinga lokucindezela komsindo.

Izindlela Zokulinganisa Zokukhetha Isikhulumi Senkulumo Yomphakathi

Isinqumo esihle kakhulu sesipikha sasefektri sisekelwe kumapharamitha angalinganiswa angahlolwa ngaphambi kokuthenga.

Ngokuhlela okuvamile kwezimboni, amaphuzu okubhekisela kuwo avamile afaka phakathi ukwakheka komsindo okusatshalaliswa okungu-70 V noma okungu-100 V, okwenza kube lula ukusebenzisa ikhebula elide kanye nokuhlelwa kwezipikha eziningi. Ezindaweni ezinzima, ukuvikelwa kokuvala kanye nehadiwe yokufaka kubaluleke kakhulu njenge-acoustic spec. Ezimweni zokusetshenziswa kwe-alamu yezwi nezimo eziphuthumayo, uhlelo kufanele futhi luhambisane nezimiso zokuklama zokuphepha empilweni kuI-ISO 7240-16.

Abathengi kufanele futhi babheke ukusabalala kwesipikha, amandla alinganisiwe, izinga lokushisa lokusebenza, kanye nokuvikelwa kwe-IP njengesethi, ngoba inombolo eyodwa enamandla ayikwazi ukuvala isikhala sokuqina okubuthakathaka kwemvelo.

Ukufakwa Kwesipikha Sefektri: Ukufakwa, Ukuhloswa, kanye Nokuhlukaniswa Kwezindawo

Ukufakwa kahle kungabaluleka kakhulu kunophawu lwesipikha uma umgomo uwukubhala amakhasi ngendlela eqondakalayo.

Ukuphakama kokukhweza kuthinta ukujikijela, kuyilapho i-engeli yokukhomba ithinta ukuthi yiziphi izisebenzi ezithola umyalezo ngempela. Endlini yokugcina impahla, isipikha se-horn esihlose phezulu kakhulu sichitha amandla ezakhiweni zophahla; sihlose phansi kakhulu, sidala izindawo ezishisayo nezindawo ezifile. Empeleni, ukuklanywa kwezindawo kubaluleke njengehadiwe ngoba izindawo ezahlukene zefektri zivame ukudinga izinto eziza kuqala zomyalezo ezahlukene.

Isu elilodwa eliphumelelayo lokwakha isitshalo ukuhlukanisa isitshalo sibe yizindawo ezisebenzayo: indawo yokukhiqiza, indawo yokulayisha, umngcele wangaphandle, kanye nemizila yokuphunyuka ephuthumayo. Leyo ndlela yenza kube lula ukuhlela ivolumu, isikhathi sokuthumela imiyalezo, kanye nezidingo zamandla okusekelayo.

• Beka izipikha ngaphezu kwezithiyo kodwa ngaphansi kwengqimba yokubonisa evelele uma kungenzeka.
• Qondisa izimpondo zakho ezindleleni zokulalela ezinabantu abaningi kunokuba ubheke endaweni engenalutho yokujikeleza kwegazi.
• Sebenzisa izindawo ezihlukene zezindawo ezinomsindo ophezulu kanye nezindawo ezinomsindo ophansi.
• Gcina ukufinyelela kokulungisa kumklamo kusukela ngosuku lokuqala.

Uma isitshalo sakho sisebenzisa nezindawo zokuxhumana eziqinile ezifanaamafoni e-VoIP ezimboni or izingcingo ezingaphazamisi umonakalo, ukufaka phakathi i-paging kanye nokuxhumana okuphuthumayo kunganciphisa umthwalo wokuqeqesha futhi kwenze kube lula ukuhlola izinqubo zokuphendula.

Izindinganiso kanye nokuqinisekiswa kwamaphrojekthi esikhulumi senkulumo yomphakathi

Izindinganiso zinikeza amaqembu okuthenga indlela yokuzivikela yokuqhathanisa iziphakamiso zezikhulumi zasefektri.

Ukuze uthole i-alamu yezwi kanye nemiyalezo ephuthumayo,I-ISO 7240-16ibaluleke kakhulu ngoba ikhuluma ngokulawulwa kwe-alamu yezwi kanye nemishini yokubonisa. Ukuze uthole izimiso ezibanzi zokuklama ukuxhumana okuphuthumayo, i-US Federal Emergency Management Agency ichaza izinto okufanele zicatshangelwe zokuxwayisa kanye nezaziso ezinsizeni zayo zokuxwayisa zomphakathi, okuhlanganisaIsiqondiso se-IPAWS. Ngokuhlela i-acoustic ezingeni lesistimu,Isiqondiso somsindo se-NISTkusalokhu kuwusizo ekuqondeni ukuthi kungani ukulawula umsindo wangemuva kubalulekile.

Lezi zinkomba azithathi indawo yokuhlola isayithi, kodwa zisiza ukuguqula ingxoxo yokuthengisa ibe ngeyobuchwepheshe. Lolo shintsho luvame ukuthuthukisa ikhwalithi yemiphumela yephrojekthi.

Amaphutha Esikhulumi Esivamile Sefektri kanye Nendlela Yokuwagwema

Iphutha elibiza kakhulu ukuthenga isikhulumi esikhulu esingakwazi ukukhuluma kahle lapho sidingeka khona.

Amaqembu amaningi acacisa ngokweqile amandla kagesi futhi achaza ngaphansi kokumbozwa. Amanye awakunaki ukulahleka kwekhebula, ukuchayeka esimweni sezulu, noma umehluko phakathi kwamathoni e-alamu nezimemezelo ezikhulunywayo. Isipikha se-PA horn singabonakala silula, kodwa ukuthunyelwa kwezimboni kusadinga ukuhlela i-acoustic, ukuhlolwa kokuhambisana kukagesi, kanye nokuhlela ukufinyelela kwesevisi.

1. Ungakhethi kuphela ngokwesilinganiso esiphezulu se-dB.
2. Ungabeki isipikha esisodwa ukuze simboze yonke indawo.
3. Ungakunaki ukuduma kwe-concrete nensimbi.
4. Ungahlanganisi izidingo ze-paging eziphuthumayo kanye nomculo wangemuva ngaphandle kokuhlukanisa indawo.
5. Ungayeki ukuhlolwa kokucaca kwangemva kokufakwa.

Indlela Yokwakha Uhlelo Lwezipikha Zefektri Olusebenza Empilweni Yangempela

Uhlelo lwezipikha olungcono kakhulu lwefektri yilolo oluhlala luqondakala ngesikhathi sokusebenza okuvamile kanye nemicimbi ebalulekile.

Umsebenzi wokukhetha osebenzayo uqala ngendawo yokulalela, hhayi ikhathalogi. Okokuqala linganisa izinga lomsindo ojwayelekile ophakeme kakhulu. Bese uchaza umlaleli okude kakhulu kanye nohlobo lomyalezo. Ekugcineni khetha ifomethi yesipikha, i-amplifier margin, kanye nephethini yokufaka eyanelisa lezo zimo ngesikhala sokuguga nokungcola.

Kubathengi bephrojekthi, abathengisi abathembeke kakhulu ngokuvamile yilabo abangasekela ukufaniswa kwesistimu eyodwa, isiqondiso sokufakwa, kanye nokuqhubeka kwezingxenye ezisele. Lokho kubalulekile ngoba amaphrojekthi okuxhumana kwezimboni awavamile ukwehluleka ngenxa yesipikha esibi kunangenxa yokuxhumana okungekuhle phakathi kwehadiwe, izintambo, kanye nokugcinwa kwayo.

• Sebenzisa isikhulumi se-PA horn ezindaweni ezikude zokuphonsa umsindo, izindawo zangaphandle, kanye nezindawo zokusebenza ezinomsindo omkhulu.
• Sebenzisa isikhulumi sekheli lomphakathi esivamile ezindaweni zangaphakathi ezidinga ukumbozwa kabanzi nomsindo oqondile othambile.
• Qinisekisa isilinganiso se-IP, ukubekezelela izinga lokushisa, kanye nehadiwe yokufaka ngaphambi kokukhishwa.
• Hlola ukuzwakala ngemva kokusebenzisa lapho kukhona umsindo wangempela wesitshalo.

Kubathengi abaqhathanisa izixazululo zokuxhumana eziqinile, indlela efanayo yokuthenga esetshenziswayoizingcingo zokuphepha zezimboniKuyasebenza nalapha: qala kusukela ku-hazard, bese ukhetha idivayisi. Leyo ndlela ithembeke kakhulu kunokuthenga ngesihloko sekhathalogi.
