Kungani Kubalulekile Ukukhuluma Kwezimboni Okufanelekile
Ezindaweni zezimboni, indawo yomsindo ayivamile ukuba yinto ecatshangwa kamuva; iyinguquko ebalulekile yokusebenza. Imishini esindayo, imigqa yokucubungula enomfutho ophezulu, kanye nemishini yokuphatha izinto ikhiqiza amaphrofayili omsindo aqhubekayo aphonsela inselelo amanethiwekhi okuxhumana ayisisekelo. Ukusebenzisa uhlelo lwesipikha sezimboni kulezi zindawo ezinzima kudinga okungaphezu nje kokukhulisa umsindo—kudinga ukuvumelanisa ngamabomu ubunjiniyela bomsindo, ukuqina kwezinto, kanye nokuhambisana nokuphepha kokuphila.
Uma amaqembu okuthenga kanye nobunjiniyela engacacisi kahle imishini yokuxhumana yomphakathi kanye ne-alamu ejwayelekile (PA/GA), ukwehluleka okubangelwayo kudlulela ngale kwekhwalithi yomsindo ephansi. Izithiyo zokusebenza zenzeka lapho imiyalelo ingezwakali ngomsindo ozungezile, futhi imiphumela emibi ingase ivele lapho izimpawu zokuphunyuka eziphuthumayo zehluleka ngesikhathi sezigameko ezibucayi. Ukukhetha okulungileisipikha sezimboni siqinisekisaukuthi ukuxhumana okubalulekile okuhloselwe umsebenzi kungena ezindaweni ezinama-decibel aphezulu ngokuthembekile, kugcina kokubili ukuqhubeka kokusebenza kanye nokunamathela ngokuqinile kwemithetho.
Izingozi Zebhizinisi Zabakhulumi Abangacacisiwe Kahle
Ukusebenzisa imishini yomsindo yezinga lezentengiselwano ezindaweni zezimboni kuletha ubuthakathaka obukhulu bebhizinisi. Ingozi eshesha kakhulu ukulahlekelwa ukuzwakala. Esikhungweni lapho umsindo ozungezile uhlala udlula khona u-85 dB(A), isikhulumi esingenalo izinga lokucindezela komsindo elifanele (i-SPL) noma impendulo yemvamisa sizokwenza imiyalo yezwi ingaqondakali, okuholela emaphutheni okukhiqiza, ukuphazamiseka komsebenzi, kanye nomonakalo wemishini ebiza kakhulu ngenxa yokuxhumana okungekuhle.
Ngaphezu kwalokho, izikhulumi ezingacaciswanga kahle zibeka izinhlangano engcupheni enkulu yokulawula kanye neyomthwalo wemfanelo. Izinhlangano zokuphepha emsebenzini zigunyaza izinhlelo ze-alamu ezicacile nezicacile. Isibonelo, ukwehluleka ukuhlinzeka ngezinhlelo zokuxwayisa zokuzwa ezifanele kungabangela izinhlawulo ezinzima, lapho izinhlangano ezilawulayo ezifana ne-OSHA zikhokhisa izinhlawulo ezingadlula u-$15,625 ngokwephulwa ngakunye ngokwephulwa kokuphepha okukhulu. Uma kwenzeka ingozi enkulu yezimboni, ukungakwazi ukufakazela ukuthi uhlelo lwesaziso esiphuthumayo luhlangabezane nemingcele edingekayo ye-acoustic kungabangela izikweletu ezinkulu zomthetho nezezezimali enkampanini esebenzayo.
Izindleko Zomjikelezo Wokuphila, Isikhathi Sokusebenza, kanye Nomphumela Wokuphepha
Izindleko zangempela zesistimu yezikhulumi zezimboni azibalwanga ekusetshenzisweni kwayo kokuqala kwemali (i-CAPEX), kodwa ezindlekweni zayo zomjikelezo wokuphila kanye nomthelela ekusebenzeni kwesikhungo.izimo zezimboni ezinzima—njengokushintshashintsha kwezinga lokushisa okukhulu, ukungena kwezinhlayiya, noma umoya ogqwalisayo—kubola ngokushesha. Isipikha esijwayelekile sezentengiselwano singase sibonise i-Mean Time Between Failures (MTBF) yamahora angu-5,000 kuya ku-10,000 endaweni engeyinhle, kodwa lokhu kwehla kakhulu esitshalweni samakhemikhali noma emshinini wokwakha.
Ngakolunye uhlangothi, isipikha sezimboni esakhelwe ngenhloso sakhiwe ukuze siphile isikhathi eside, sivame ukuba ne-MTBF engaphezu kwamahora angu-50,000 ngisho nangaphansi kokucindezelwa okuqhubekayo. Ngenkathi izindleko zangaphambili zeyunithi yezimboni zingase zibe ngaphezulu ngokuphindwe kathathu kuya kahlanu kunenye indlela yezentengiselwano, ukonga emsebenzini wokulungisa, izingxenye ezishintshayo, kanye nesikhathi sokuphumula esigwenyiwe kuveza izindleko eziphansi kakhulu zobunikazi (TCO) esikhathini sokuphila kokusebenza seminyaka eyi-10. Okubaluleke kakhulu, isikhathi esiqinisekisiwe sokusebenza kwesipikha esiqinile siqinisekisa ukuthi izinhlelo zokuphepha empilweni zihlala zisebenza, zivikela ngqo abasebenzi futhi zinciphise ingozi yokuvalwa kwezikhungo zonke.
Yini Echaza Isikhulumi Sezimboni Esinonya Esingokwemvelo
Ukuchaza isikhulumi sezimboni kudinga ukubheka ngale kwamandla ayisisekelo kanye nokuphendula kwemvamisa. Isikhulumi semvelo esinzima ngempela sihlukaniswa ngokusinda kwaso ezimweni ezimbi kakhulu kanye nekhono laso lokuveza umsindo ocacile ngokusebenzisa izimo eziyinkimbinkimbi, ezinomsindo ophezulu. Lawa madivayisi aklanywe ukuze asebenze ekuxhumaneni kwesayensi yezinto eziqinile kanye ne-acoustic dynamics ekhethekile.
Ukuze bahlole kahle isipikha sezimboni, abahlanganisi bezinhlelo kumele bahlole izinto ezithile ezicindezela indawo yokufaka futhi bazifanise nezincazelo zokuvikela kanye ne-acoustic zedivayisi. Lokhu kuqinisekisa ukuthi isipikha ngeke sisinde endaweni ebonakalayo kuphela kodwa futhi sizofeza umsebenzi waso oyinhloko: ukuletha umsindo oqondakala kalula.
Izinhlelo Zomsindo Zezimboni Nezentengiselwano
Umehluko phakathi kwezinhlelo zomsindo zezimboni nezentengiselwano utholakala kakhulu ezintweni zokwakha kanye nokubekezelela ukushisa. Izikhulumi zezentengiselwano zivame ukusebenzisa amapulasitiki e-ABS, amakhowuni ephepha, kanye nokuvikela isimo sezulu okuyisisekelo okufanelekela izindawo zokuthengisa ezilawulwa yisimo sezulu noma amahhovisi. Uma zivezwa emisebeni ye-UV, umusi wamakhemikhali, noma amazinga okushisa aphezulu, lezi zinto ziyagoba, zonakale, futhi ekugcineni zihluleke.
Izipikha zezimboni zenziwe ngama-polycarbonate anamandla aphezulu, azinze nge-UV, i-aluminium yezinga lolwandle, noma insimbi engagqwali engu-316L. Izingxenye zazo zangaphakathi zine-phenolic noma i-titanium diaphragms ephathwayo emelana nomswakama kanye nokuwohloka kwamakhemikhali. Ngokushisa, isipikha sezimboni senzelwe ukusebenza ngaphakathi kwebhendi yokushisa ebanzi kakhulu, ngokuvamile kusukela ku--40°C kuya ku-+70°C, ukuqinisekisa ukusebenza kokubili emagcekeni angaphandle aqandisayo kanye namakamelo okubhoyila ashisayo.

| I-MTBF ejwayelekile | Amahora angu-5,000 - 10,000 | Amahora angaphezu kuka-50,000 |
Izimo Ezibalulekile Zemvelo Okufanele Zihlolwe
Ngaphambi kokukhetha isikhulumi, ukuhlolwa okuphelele kwemvelo kwendawo yokufaka kuyimfuneko. Izinto eziyinhloko ezicindezelayo zifaka phakathi izinhlayiya eziphuma emoyeni (uthuli, izingcezu zensimbi), umswakama (umswakama ophezulu, imvula eqondile, ukungcola okunomfutho ophezulu), kanye nokuchayeka kumakhemikhali (amagesi agqwalisayo, ukufuthwa kukasawoti ezindaweni ezingaphandle kolwandle).
Ukudlidliza kanye nokushaqeka nakho kuyizinto ezibalulekile, ikakhulukazi ekukhiqizweni okunzima noma eduze kwemishini emikhulu ejikelezayo. Izikhulumi kulezi zindawo kumele zihambisane nezindinganiso zobuqotho besakhiwo, njenge-MIL-STD-810G, ukuqinisekisa ukuthi ukudlidliza okuqhubekayo okunemvamisa ephansi akukhululi amakhoyili ezwi angaphakathi noma amabhuleki okufaka. Ukuhlola lezi zimo kunquma ukuvikelwa kokungena okudingekayo kanye nezinto zokuvala ezidingekayo ukuvimbela ukwehluleka kwangaphambi kwesikhathi.
I-SPL, Ukuqondisisa, kanye Nokuhlakazeka Komsindo
Ukusebenza kwe-acoustic ezindaweni ezinzima kuchazwa ngama-metric amathathu: Izinga Lokucindezela Komsindo (i-SPL), ukuzwakala kahle, kanye nokusabalala komsindo. Ukuze kunqotshwe umsindo wezimboni ozungezile, isikhulumi kumele sikhiqize i-SPL okungenani engu-+10 dB kuya ku-+15 dB ngaphezu kwezinga lomsindo wangemuva oqhubekayo endaweni yomlaleli. Isibonelo, uma igumbi le-compressor lisebenza ku-90 dB(A), isikhulumi kumele sinikeze i-100-105 dB(A) endaweni yomqhubi.
Kodwa-ke, ivolumu ephelele ayanele ngaphandle kokuqondakala, okukalwa yi-Speech Transmission Index (STI). Isilinganiso se-STI esingaphezu kuka-0.50 ngokuvamile siyadingeka ukuze kuqondwe kahle izwi. Ukufeza lokhu kudinga izikhulumi ezinempendulo yemvamisa elungiselelwe inkulumo yomuntu (ngokuvamile engu-300 Hz kuya ku-4,000 Hz) kanye nama-engeli okusabalala alawulwayo. Izimpondo zokusabalala ezincane (isb., ama-degree angu-60 kuya kwangu-70) zisetshenziselwa ukushaya umsindo emabangeni amade ngaphandle kokudala ukuzwakala ngokweqile, kuyilapho amakhabethe okusabalala abanzi (afinyelela kuma-degree angu-120) elungele kangcono ukumbozwa kabanzi ezindaweni zokuhlangana ezinomsindo ophansi, ezivulekile.
Imininingwane Yokuqina Nokuvikelwa
Ukuqina komzimba kwesipikha sezimboni kulinganiswa ngezinhlelo zokulinganisa zomhlaba wonke ezijwayelekile. Lezi zincazelo zinikeza uhlaka oluthembekile lokufanisa ihadiwe nobunzima obuqondile bendawo, okuqinisekisa ukuthi izinto zobuchwepheshe zangaphakathi zihlala zihlukanisiwe namandla angaphandle abhubhisayo.
Ukuqonda ukuthi ungahumusha kanjani futhi usebenzise kanjani lezi zici zokuvikela—kusukela ekuvimbeleni amanzi okuyisisekelo kuya ekuqinisekisweni okuthuthukisiwe okuvimbela ukuqhuma—kuyisisekelo sokucacisa uhlelo lwe-PA/GA lwezimboni oluthembekile.
Izilinganiso ze-IP, Izinhlobo ze-NEMA, kanye nokumelana nokugqwala
Izilinganiso Zokuvikela Ukungena (IP) kanye nezinhlobo ze-National Electrical Manufacturers Association (NEMA) ziyizinkomba eziyinhloko zokuqina kwesipikha. Uhlelo lokulinganisa i-IP lusebenzisa izinombolo ezimbili: elokuqala libonisa ukuvikelwa ezintweni eziqinile (uthuli), kanti elesibili libonisa uketshezi (amanzi). Ezindaweni zezimboni ezinzima, i-IP66 (ukuvikelwa olwandle olunzima noma amajethi amanzi anamandla) noma i-IP67 (ukuvikelwa ekucwilisweni okwesikhashana) yizona zindlela ezijwayelekile.
ENyakatho Melika, izilinganiso ze-NEMA zivame ukusetshenziswa kanye nezilinganiso ze-IP, okunikeza umongo owengeziwe mayelana nokumelana nokugqwala. Isilinganiso se-NEMA 4X, isibonelo, asiqinisekisi nje kuphela ukuvikelwa othulini olupheshulwa umoya kanye namanzi aqondiswa yipayipi kodwa futhi siqinisekisa ukumelana nokugqwala. Ukufeza lokhu kuvame ukudinga ukuthi indawo yesipika kanye namabhuleki okufakwayo akhiwe ngensimbi engagqwali engu-316L noma ama-polyester aqiniswe ngengilazi (GRP) akhethekile.
| Isilinganiso se-IP | I-NEMA Equivalent (Cishe) | Incazelo Yezinga Lokuvikela | Isicelo Esijwayelekile Sezimboni |
|---|---|---|---|
| I-IP54 | I-NEMA 3 | Kuvikelwe uthuli, amanzi agelezayo | Ukuhlanganiswa okulula, izindawo zokugcina impahla zangaphakathi |
| I-IP66 | I-NEMA 4 | Amajethi amanzi aqinile, aqinile | Izindawo zokugeza, amagceke angaphandle |
| I-IP67 | I-NEMA 4X | Uthuli luqinile, ukucwiliswa kwesikhashana | Ukucubungula amakhemikhali olwandle/olwandle, |
Lapho Kudingeka Izipikha Ezingaqhumi
Ezindaweni lapho kukhona khona amagesi avuthayo, umusi, noma uthuli oluvuthayo—njengezindawo zokuhlanza i-petrochemical, ama-elevator okusanhlamvu, noma izimboni zokukhiqiza upende—izikhulumi zezimboni ezijwayelekile zibeka engcupheni yokushisa. Kulezi zindawo eziyingozi, izikhulumi ezingaqhumi noma eziphephile ngokwazo ziyadingeka ngokomthetho. Lawa madivayisi alawulwa kakhulu yizinhlaka ezifana ne-ATEX ne-IECEx eYurophu, kanye nohlelo lwe-National Electrical Code (NEC) Class/Division eNyakatho Melika.
An isikhulumi esingaqhumi(isib., ekalwe i-ATEX Zone 1 noma i-Class I, Division 1) inesivalo esingashisi umlilo (Ex d). Lo mklamo uqinisekisa ukuthi uma iphutha likagesi langaphakathi lidala inhlansi evuthela igesi ezungezile ngaphakathi kwendlu yesipikha, isivalo sizoqukatha ukuqhuma futhi sipholise amagesi okukhipha umoya aphumayo ngaphansi kwezinga lokushisa lokushisa okuzenzakalelayo lomkhathi ozungezile. Ukucacisa la mayunithi kudinga ukulingana okunembile kwesitifiketi sesipikha neqembu eliqondile legesi (isib. IIB, IIC) kanye nesigaba sokushisa (isib. T4, T6) sesikhungo.
Ukuqhathanisa Izipikha Ze-Horn, IKhabhinethi, kanye Ne-Paging
Izipikha zezimboni ngokuvamile ziwela ezicini ezintathu: izipikha ze-horn, izipikha zekhabhinethi, kanye namaphrojektha e-paging akhethekile. Izipikha ze-horn ziyindinganiso yezindawo ezinomsindo omkhulu. Zisebenzisa umshayeli wokucindezela ohambisana nophondo oluvuthayo, zisebenza kahle kakhulu, ngokuvamile zikwazi ukukhiqiza ama-SPL angaphezu kuka-120 dB kumitha eli-1. Indlela yazo yokuqondisa izenza zilungele ukungena emsindweni ophezulu ozungezile amabanga amade, yize impendulo yazo yemvamisa ithambekele kakhulu kumaza aphakathi naphezulu, okwenza zingabi mnandi kumculo wangemuva.
Izipikha zekhabhinethi nezephrojektha zisetshenziswa lapho kudingeka impendulo ebanzi yemvamisa kanye nokuthembeka okuphezulu komsindo, njengasemagumbini okulawula noma phansi okukhiqiza umsindo ophansi. Ngenkathi zinikeza i-STI engcono kakhulu yemiyalezo yezwi eyinkimbinkimbi, zivame ukuphuma kakhulu kuma-SPL aphansi (90 kuya ku-105 dB kumitha eli-1) futhi zidinga amandla e-amplifier amaningi ukuze kufinyelelwe indawo efanayo yokumboza njenge-horn. Ukukhetha phakathi kwalezi zinhlobo kuhilela ukulinganisela isidingo sokungena kwe-acoustic engavuthiwe ngokumelene nesidingo sokuthembeka komsindo.
Ukuhlanganiswa, Ukuthobela, kanye Nezindleko
Ukuthola isipikha sezimboni kuyingxenye nje yesilinganiso; ukusihlanganisa kunethiwekhi yokuxhumana yesikhungo sonke kuletha izinguquko eziyinkimbinkimbi zikagesi, zomthetho, kanye nezezezimali. Isipikha kumele sixhumane kalula nengqalasizinda yokukhulisa ekhona ngenkathi sinamathela kumakhodi okuphepha kokuphila esifundeni.
Ukuhlola izidingo zokuhlanganiswa kusenesikhathi kuvimbela ukwakhiwa kabusha okubizayo ngesikhathi sokufakwa futhi kuqinisekisa ukuthi uhlelo olusetshenzisiwe lusebenza kahle esikhathini sokuphila kwalo esihlosiwe.
Ukuhambisana kwe-Voltage, Impedance, kanye ne-Amplifier
Izinhlelo ze-PA/GA zezimboni zivame ukusebenzisa imigqa yomsindo esatshalaliswa ngamandla aphezulu—ngokuvamile i-70V eNyakatho Melika kanye ne-100V emhlabeni jikelele—kunezinhlelo ze-8-ohm low-impedance ezitholakala kumsindo wabathengi. Le ndlela ye-high-voltage inciphisa ukulahlekelwa kwamandla ngesikhathi sokusebenza kwekhebula isikhathi eside okudingekayo ezindaweni ezinkulu zezimboni, okuvumela izikhulumi eziningi ukuthi ziboshwe ngentambo ende esiteshini esisodwa se-amplifier.
Ukuze zixhumane nalezi zinhlelo, izikhulumi zezimboni zihlonyiswe ngama-transformer angaphakathi aphansi. Lawa ma-transformer aqukethe “ama-wattage” amaningi (isib. 1W, 2W, 4W, 8W, 15W, 30W), okuvumela abafaki ukuthi balungise ukudonsa kwamandla kanye ne-SPL ephumelayo yesipika ngasinye ngokuya ngendawo yaso ethile. Ukubalwa okufanele kwama-transformer taps kubalulekile; i-wattage iyonke yazo zonke izikhulumi ezifakwe kulayini akumele idlule u-80% wekhono lokukhipha elilinganisiwe le-amplifier ukuvimbela ukugcwala kwe-transformer kanye nokwehluleka kwe-amplifier.
Izitifiketi kanye namazinga esifunda
Ukuhambisana nezindinganiso zesifunda kanye nezinhlelo zokusebenza ezithile akunakuxoxiswana ngazo ezinhlelweni zomsindo zezimboni, ikakhulukazi uma zisebenza njengamanethiwekhi okuphuma kwabantu eziphuthumayo. ENyakatho Melika, izikhulumi ezisetshenziselwa ama-alamu omlilo kanye nezimpawu eziphuthumayo kumele ziqinisekiswe yi-UL 1480 (Fire Protective Signaling Systems). EYurophu, izinga elifanayo yi-EN 54-24, elibeka imigomo yokusebenza eqinile yezikhulumi ze-alamu yezwi.
Ngaphezu kwalokho, izikhulumi ezithunyelwe emikhakheni ethile kumele zihlangabezane nezitifiketi ezikhethekile. Izikhulumi zasemanzini nezasogwini zivame ukudinga imvume evela emiphakathini yokuhlukanisa njenge-DNV noma i-ABS. Ukuthobela iziqondiso zemvelo, njengokuthiI-RoHS kanye ne-REACH, kuyadingeka futhi ekuthengweni komhlaba wonke. Ukuqinisekisa lezi zitifiketi ngesikhathi sesigaba sokukhetha kuqinisekisa ukuthi ukufakwa kuzodlula ukuhlolwa kokugcina kokuphepha kanye nokuhlolwa yiziphathimandla zasekhaya ezinegunya (AHJ).
Ukufakwa kanye Nezindleko Zobunikazi Eziphelele
Ukufakwa okungokoqobo kwezipikha zezimboni kuthonya kakhulu Izindleko Zobunikazi Eziphelele (i-TCO). Izipikha ezisindayo ezingaqhumi zingaba nesisindo esiphakathi kwama-5 kg nama-15 kg, okudinga amabhulakhethi okubamba aqinile, angadlidlizi—ngokuvamile amabhulakhethi ensimbi engagqwali ajikelezayo avumela ukuqondiswa okunembile kwe-acoustic. Izindleko zokusebenzisa izintambo ezikhethekile ezivikelwe noma ezingashisi umlilo kula mayunithi zingavame ukudlula izindleko zezipikha ngokwazo.
Uma kubalwa i-TCO, amaqembu okuthenga kumele abheke ngale kwentengo yokuqala yeyunithi, evame ukuba phakathi kuka-$300 no-$800 ngezimpondo zezimboni ezijwayelekile, kanye no-$2,000 ngezinyunithi ezikhethekile eziqinisekiswe yi-ATEX. Isipikha esishibhile nesingenamandla kangako sizobiza izindleko ezinkulu zomsebenzi ngomsebenzi wokufaka esikhundleni ophezulu, ukuqasha izisekelo, kanye nokumiswa kokukhiqiza okungenzeka. Ukutshala imali kuyunithi eqinile kakhulu, eqinisekiswe ngokufanele kunciphisa kakhulu ukungenelela kokulungisa, kuholele ku-TCO ephansi futhi kunikeze ukumbozwa kokuphepha okuthembekile unyaka nonyaka.
Uhlaka Lokukhetha Izipikha Zezimboni
Ukukhetha isipikha sezimboni esifanele kudinga indlela ehlelekile ehlanganisa isayensi ye-acoustic nobunjiniyela bezikhungo. Ukuthembela ekuqageleni noma ukukopisha imininingwane yakudala kuvame ukuholela ezinhlelweni ezingasebenzisi amandla anele noma ezibiza kakhulu ngokungadingekile.
Ngokusebenzisa uhlaka lokukhetha oluhlelekile, abaphathi bezikhungo, onjiniyela be-acoustic, kanye nezikhulu zokuthenga bangacacisa ngokuqiniseka imishini ehlangabezana nezidingo zokusebenza nezokuphepha eziqondile.
Inqubo Yokukhetha Isinyathelo Ngesinyathelo
Inqubo yokukhetha kumele iqale ngokuhlola okuphelele kwe-acoustic yesikhungo. Onjiniyela kumele bahlele amazinga omsindo ozungezile ku-dB(A) kuzo zonke izindawo zokusebenza ezahlukene ngesikhathi sokukhiqiza okuphezulu. Ngemva kokuhlola kwe-acoustic, kwenziwa ukuhlolwa kwemvelo ukuze kutholakale ukuthi kukhona umswakama, uthuli, amazinga okushisa aphezulu, kanye namagesi aqhumayo. Lokhu kuchaza izilinganiso ze-IP, i-NEMA, kanye ne-ATEX/Indawo Eyingozi ezidingekayo.
Okulandelayo, ukwakheka kwesistimu kumele kuhlolwe. Izipikha ezikhethiwe kumele zihambisane nengqalasizinda ye-amplifier yesikhungo (isb., ukuhambisana komugqa we-70V/100V) kanye nesabelomali samandla esiphelele. Okokugcina, ukubuyekezwa kwezimfuneko zomthetho wendawo kunquma izitifiketi ezithile zokuphepha empilweni (njenge-UL 1480 noma i-EN 54-24) ihadiwe okumele ithwale. Ukulandela lezi zinyathelo ezine kuqinisekisa inqubo yokuthenga ezwakalayo nehambisanayo ngokobuchwepheshe.
Ukulinganisela Ukusebenza Kwe-Acoustic Nokuqina
Inselele eqhubekayo ekwakhiweni komsindo wezimboni ukulinganisela ukusebenza kwe-acoustic nokuqina ngokomzimba. Izinto ezihlala isikhathi eside kakhulu, njenge-aluminium ejiyile noma izivalo ezingaqhumi, zisebenza kahle ekuvikeleni izingxenye zangaphakathi kodwa zinganciphisa umsindo we-acoustic futhi zinciphise impendulo yemvamisa. Lokhu kunganciphisa kancane umsindo wemvelo womsindo wezwi uma kuqhathaniswa namakhabethe amancane, asezingeni lokuhweba.
Ukuze kuncishiswe lokhu, abaklami bezinhlelo kumele babeke phambili ukuqonda kunomculo osezingeni eliphezulu. Ngokukhetha izikhulumi ezinejika elijwayelekile elilungiselelwe ububanzi bezwi lomuntu (elikhulisa ibhendi engu-1 kHz kuya ku-4 kHz), uhlelo lungafinyelela i-Speech Transmission Index (STI) ephezulu naphezu kokuvalwa okunzima nokuqinile. Ngaphezu kwalokho, ukusebenzisa izikhulumi eziningi ezinama-wattage aphansi ezisatshalaliswe ngendlela efanele endaweni yonke kuvame ukuveza ukuqonda okungcono kanye nokumbozwa okulinganayo kunokuthembela ku-horn eyodwa enamandla amakhulu edala ama-hotspots nama-echoes angavamile.
Uhlu Lokuhlola Lokugcina Lokucaciswa
Ngaphambi kokuphothula i-oda lokuthenga, amaqembu obunjiniyela kanye nokuthengwa kwempahla kufanele abhekisele kuhadiwe ayikhethile ngokumelene nohlu lokuhlola lokugcina lokucacisa. Okokuqala, qinisekisa ukuphuma kwe-acoustic: ingabe i-SPL yesipikha ku-wattage ethephiwe inikeza i-+15 dB edingekayo ngaphezu komsindo ophezulu we-ambient ebangeni lomlaleli? Qinisekisa ukuthi i-engeli yokusabalala ihambisana nokwakheka okubonakalayo kwendawo ukuze kuncishiswe amandla e-acoustic asetshenzisiwe.
Okwesibili, qinisekisa imininingwane engokwenyama neyokulawula. Qinisekisa ukuthi isilinganiso se-IP sihambisana nokuchayeka okubi kakhulu kwemvelo, njengokuwasha okunamandla okudinga i-IP66. Qinisekisa ukuthi isitifiketi sendawo eyingozi sifana ngqo nesigaba seZone noma seDivision sendawo yokufaka. Okokugcina, qinisekisa ukuthi ihadiwe yokufaka ilinganiswe ngesisindo sesipikha (ngokuvamile kusuka ku-5kg kuya ku-15kg kumayunithi ezimboni asindayo) kanye nephrofayili yokudlidliza yesayithi. Ukugcwalisa lolu hlu lokuhlola kuqinisekisa ukuthunyelwa kohlelo lomsindo lwezimboni oluqinile, olusebenzayo, noluhambisanayo.
Izinto Ezibalulekile Okufanele Uzicabangele
- Cacisa izikhulumi zezimboni ngokwezinga lomsindo ozungezile, i-SPL edingekayo, ibanga lokumboza, kanye nokuzwakala kwezwi kunokuba kube yi-wattage yodwa.
- Gwema izipikha zezinga lokuhweba ezindaweni ezinzima ngoba uthuli, umswakama, ukugqwala, ukudlidliza, kanye nokushintshashintsha kwezinga lokushisa kungabangela ukwehluleka okusheshayo.
- Ezindaweni eziyingozi njengowoyela negesi, izimayini, noma ukucutshungulwa kwamakhemikhali, qinisekisa izitifiketi ezidingekayo ezingaqhumi njenge-ATEX ngaphambi kokuthenga.
- Cabanga ngezindleko zomjikelezo wokuphila ngoba izikhulumi zezimboni eziqinile zinganciphisa ukushintshwa, ukulungiswa, isikhathi sokungasebenzi, kanye nokwehluleka kohlelo lokuphepha esikhathini sokusebenza seminyaka eyi-10.
- Hlanganisa izikhulumi nezinhlelo ze-PA/GA, i-paging, i-VoIP, i-intercom, kanye nezingcingo eziphuthumayo ukuqinisekisa ukuthi ama-alamu nemiyalelo kufinyelela kubasebenzi ngokuthembekile.
imibuzo ejwayelekile ukubuzwa
Yini eyenza isipikha sezimboni sifanelekele izindawo ezilukhuni?
Isipikha esifanelekile sezimboni sihlanganisa izinga lokucindezela komsindo eliphezulu, izinto ezihlala isikhathi eside ezivalekile, ukumelana nokugqwala, ukuvikelwa kokungena, ukubekezelela izinga lokushisa, kanye nokuzwakala kwezwi okucacile. Ezindaweni eziyingozi, kufanele futhi sihlangabezane nezitifiketi ezifanele njenge-ATEX noma ezinye izindinganiso zokuphepha ezisebenzayo.
Kufanele kube nomsindo ongakanani isikhulumi sezimboni endaweni enomsindo?
Isipikha kumele sibe nomsindo ophakeme ngokwanele ukuze sinqobe umsindo ozungezile ngenkathi silondoloza ukuzwakala. Ezindaweni ezingaphezu kuka-85 dB(A), amaqembu kufanele abale i-SPL edingekayo ebangeni labalaleli futhi acabangele indawo yesipikha, ama-engeli okumboza, kanye nomklamo wohlelo lwe-PA/GA.
Kungani ungasebenzisi izikhulumi zezentengiselwano ezindaweni zezimboni?
Izipikha zezentengiselwano azenzelwe uthuli, umswakama, ukudlidliza, ukugqwala, amazinga okushisa aphezulu, noma izimo eziqhumayo. Zingase zingasebenzi ngokushesha, zinciphise ukucaca kwemiyalezo ephuthumayo, zandise izindleko zokulungisa, futhi zidale izingozi zokuthobela imithetho noma zomthwalo wemfanelo.
Ingabe izipikha ezingaqhumi ziyadingeka ezindaweni zikawoyela, igesi, noma zezimayini?
Kungadingeka lapho kukhona amagesi avuthayo, umusi, noma uthuli. Izikhungo kufanele zilandele izidingo zokuhlukaniswa kwezindawo eziyingozi futhi zikhethe imishini eqinisekisiwe, njengemikhiqizo yokuxhumana enesilinganiso se-ATEX, lapho kufanele khona.
Ukukhethwa kwesipikha kuthinta kanjani izindleko eziphelele zobunikazi?
Isipikha sezimboni esiqinile singabiza kakhulu kusengaphambili, kodwa singanciphisa ukushintshwa, abasebenzi bokulungisa, isikhathi sokungasebenzi, kanye nokwehluleka kokuxhumana okuphuthumayo. Amayunithi akhiwe ngenhloso anganikeza impilo yesevisi ende kakhulu kunezinye izindlela zokuhweba ezimweni ezinzima.
