Imoto eshayela emgwaqeni izoba nomsindo omkhulu ngaphakathi kwendawo yabagibeli yemoto.Lo msindo waziwa ngele-“ambient noise”.Umsindo we-ambient uzoncika ezintweni ezimbalwa, okuhlanganisa umsindo wenjini, umsakazo, isistimu ye-HVAC, nokungqubuzana kwamathayi agingqika phezu komgwaqo.Umsindo ozungezile ngaphakathi kwemoto yabagibeli ehamba amakhilomitha angu-45 ngehora (mph) ngokuvamile uba phakathi kwama-decibel angu-65 (dB).

Okweinhlabamkhosiukuze izwakale ngempumelelo umshayeli ovamile, kufanele ingene emzimbeni wemoto futhi ibe phezulu kunomsindo okhona.Ucwaningo luye lwabonisa ukuthiinhlabamkhosiIzinga kufanele likhuphuke cishe ngo-10 dB ngaphezu komsindo we-ambient ukuze kwephule ngempumelelo ukugxilisa ingqondo komshayeli.Uma umsindo we-ambient ngaphakathi kwemoto yabantu ungu-65 dB, inhlabamkhosi kufanele ikhuphuke ibe ngu-75 dB.

Isakhiwo semoto yesimanje yakhelwe ukugcina umsindo OUT.Ngokwesilinganiso, imoto yesimanje izovimba cishe ama-decibel angu-30-40 ukuze ungangeni endaweni yabagibeli yemoto.Lokhu kwaziwa ngokuthi "ukulahlekelwa kokufakwa."Uma umshayeli ongekho emthethweni edinga ama-decibel angama-75inhlabamkhosiumsindo wokusabela, iinhlabamkhosikufanele ifike ngaphandle kwefasitela lomshayeli cishe ngama-decibel angu-110, kucatshangwa ukuthi ukulahlekelwa kokufakwa okumaphakathi okungu-35 dB.

2 Isilinganisi semitha yezinga lomsindo.

Inkinga

Iningiizinhlabamkhosizilinganiselwa ku-124 dB uma zikalwa ngamafidi ayi-10 ngaphambi kwe-inhlabamkhosi.Njengoba ibanga ukusuka ku-siren liphindwe kabili, ingcindezi yomsindo we-siren izokwehla cishe ngo-6 dB.Lo mqondo waziwa ngokuthi "umthetho wesikwele ophambene."

Kubalulekile ukuqonda ukuthi lokhu kwehla okungu-6-dB kuzinga lokucindezela komsindo kuthatha ukuthi ibanga elilinganisiwe liphambi ngqoinhlabamkhosi.Lapho izilinganiso zengcindezi yomsindo zithathwa nge-engeli engu-90-degree ukusuka ku-inhlabamkhosi, ukwehla kwe-6-dB kungase kubaluleke kakhulu.Ucwaningo luye lwabonisa ukuthi ukuncipha kwezinga lokucindezela komsindo ezimpambanweni zomgwaqo ezingu-90 kungase kube phezulu njengo-11 dB.Leli yiphuzu lokufundisa elibalulekile, njengoba ukuphahlazeka ezimpambanweni zomgwaqo kwenzeka lapho izicishamlilo nemoto yabantu isondelana nge-engeli engu-90-degree.

Kubalulekile futhi ukuqaphela ukuthi kungase kube nezikhathi lapho umthamo we-siren ungehli ngo-6 dB isikhathi ngasinye lapho ibanga elisuka ku-siren liphindwe kabili.Lokhu kuvame ukubonakala ezindaweni zasemadolobheni lapho inhlabamkhosi ibonakala ingaphandle kwezakhiwo, itiyela, nezinye izindawo ezenziwe umuntu.Kulezi zimo, inhlabamkhosi ingase ingalahlekelwa umthamo omningi, kodwa ukubukeka kwenhlabamkhosi kwenza kube nzima ukunquma ukuthi ivelaphi.Kuzophinde kube nezikhathi lapho inhlabamkhosi izokwehla khona ngaphezu kuka-6 dB isikhathi ngasinye lapho ibanga ukusuka ku-siren liphindwe kabili ngenxa yokuqondisa kwesipikha se-siren kanye nezithiyo endleleni yomsindo.

Umsindo we-ambient, ukulahlekelwa kokufaka, kanye nomthetho oyisikwele ophambene uchaza ububanzi obunomkhawulo obusebenzayo be-siren.I-physics yomsindo izonciphisa ivolumu ye-siren njengoba ibanga elisuka ku-siren likhuphuka.Ngezimoto zanamuhla, ububanzi obusebenzayo be-siren ezimpambanweni zomgwaqo ezingama-90-degree ngokuvamile abukho ngaphezu kwamamitha angama-80.

Iqiniso

https://www.senkencorp.com/electronic-sirens-and-speakers/low-frequency-siren-for-police-vehicles.html

Cabanga ukuthi umshayeli ovamile udinga i-110 dB yomsindo we-siren ngaphandle kwefasitela lomshayeli ukuze ezwe inhlabamkhosi ngempumelelo.Ngokusebenzisa umthetho oyisikwele ophambene, izinga lokucindezela komsindo wenhlabamkhosi lizokwehla libe ngaphansi kuka-110 dB cishe ngamamitha angu-80.

4 Ukusetha kwebanga eliphezulu/eliphansi kumitha yezinga lomsindo.

https://www.senkencorp.com/electronic-sirens-and-speakers/standard-emergency-vehicle-siren-amplifiers.html

Uma imoto yomphakathi ihamba u-45 mph, kuzothatha umshayeli cishe amafidi angu-195 ukuze abone, asabele, futhi ashibilike ukuze ame emgwaqeni owomile.kanye umshayeli ezwa inhlabamkhosi.Uma umshayeli ezwa inhlabamkhosi iqhele ngamamitha angu-80 ezimpambanweni zomgwaqo futhi kuthatha amafidi angu-200 ukuze ame, umshayeli ngeke abe naso isikhathi sokuvula indlela uma ngabe izicishamlilo ziphumela empambanweni yomgwaqo.Lo mqondo uchaza isidingo sokuma okuphelele ezimpambanweni zomgwaqo ezingezinhle.

Abafundi abaningi bazobuza, "Kungani ungayenzi i-siren ibe phezulu?"Isizathu sokuthi ama-siren angakwazi ukuzwakala kakhulu ukuthi inhlabamkhosi ephezulu ingaholela ezinkingeni zokuzwa kwabacimi bomlilo futhi iphazamise umphakathi ozungezile ize ibe sezingeni elingamukelekile.Ngalezi zizathu, ivolumu yenhlabamkhosi yemoto yezimo eziphuthumayo kufanele ilinganiselwe.

Ukuqeqeshwa Kwezandla

Kubalulekile kubafundisi be-EVOC ukuthi banikeze ukuqeqeshwa okusebenzayo ukuze baqinise umqondo wemikhawulo ye-siren.Lokhu kuqeqeshwa kungenziwa kusetshenziswa imitha yezinga lomsindo, i-tripod, ne-siren yemoto yezimo eziphuthumayo.

Imitha Yezinga Lomsindo:Imitha yezinga lomsindo ingathengwa ngokushibhile esitolo esihlinzeka ngokuphepha.Kunezinhlobo ezahlukene zamamitha wezinga lomsindo, futhi uhlobo ngalunye luhluka ngentengo.Imitha Yekilasi 1 inembe kakhulu, kodwa imitha Yekilasi 2 izokwanela njengethuluzi lokuqeqesha (isithombe 1).
Isilinganisi Semitha Yezinga Lomsindo:Kubalulekile ukulinganisa imitha yezinga lomsindo ngaphambi kweseshini ngayinye yokuqeqesha usebenzisa isilinganisi sezinga lomsindo.Nakuba isikali singabiza, sizoqinisekisa ukuthi izilinganiso zeleveli yomsindo zinembile (isithombe 2).
I-Tripod:Amamitha amaningi weleveli yomsindo anganamathiselwa ku-tripod yekhamera.I-tripod izovumela umfundi ukuthi asethe imitha yezinga lomsindo endaweni engashintshi futhi ahlehle aye endaweni ephephile ngenkathi inhlabamkhosi ikalwa.Ungami endaweni yomsindo we-siren ukuze uthathe izilinganiso.Vikela ukuzwa kwakho.
Ukuphepha:Khumbula ukwenza isiqiniseko sokuthi umfundi ngamunye ugqoke isivikelo sokuzwa esifanele.Futhi, khumbula ukwenza isiqiniseko sokuthi wonke umuntu umi EMVA kwesipikha se-siren lapho inhlabamkhosi ihlolwa.Abafundi kufanele baye esinyathelweni esingemuva se-apparasi ukuze babavikele emisindweni eyeqile.Ungami phambi kwenhlabamkhosi!

Izilungiselelo Zemitha Yezinga Lomsindo

I-dBA vs. dBC:Amamitha weleveli yomsindo ngokuvamile anezilungiselelo ezimbili ze-decibel: i-dBA ne-dBC.Isethingi ye-dBA noma i-dBC izonquma ukuthi imitha ihlunga kanjani amaza omsindo.Lapho wenza izivivinyo zokuqeqesha, sebenzisa ukulungiselelwa kwe-dBA njengoba lokhu kulingisa ngokunembe kakhudlwana ukuthi indlebe yomuntu izowuzwa kanjani umsindo (isithombe 3).
Phezulu/phansi:Esinye isilungiselelo esivamile kumitha yezinga lomsindo ukulungiselelwa "okuphezulu/okuphansi".Isethingi "ephezulu/ephansi" isekelwe kuvolumu yomsindo olinganisiwe.Uma imitha iseduze ne-siren, sebenzisa ukulungiselelwa "okuphezulu".Njengoba imitha ihanjiswa kude ne-siren, shintsha imitha endaweni "ephansi".Bheka imiyalelo yomkhiqizi ukuze unqume ibanga elifanele eliphezulu/eliphansi lemitha yakho (isithombe 4).
Isilungiselelo esithi "Max":Izinsimbi “zishanela” phezulu naphansi, okuzobangela ukufundwa kwe-decibel esikrinini sokubonisa ukuthi kushintshe njalo.Isilungiselelo esithi "ubukhulu" sizobamba ukufundwa kwenhlabamkhosi ephezulu kakhulu phakathi nokuhlolwa.Lokhu kwenza kube lula ukurekhoda idatha.Empilweni yangempela, izinga lokucindezela komsindo we-siren lizoshaya kuphela lokhu kufundwa okuphezulu ngezikhathi ezithile, ngokusekelwe endleleni inhlabamkhosi eshanela ngayo phezulu naphansi.Qinisekisa ukuthi abafundi bayaqonda ukuthi ukufunda "okuphezulu" kuyisimo esingcono kakhulu somsebenzisi wezicishamlilo (isithombe 5).
Kuyashesha/kuhamba kancane:Lesi silungiselelo sizonquma ukuthi imitha yeleveli yomsindo iwusampula ngokushesha kangakanani umsindo.Ngenxa yokukhuphuka nokuwa okusheshayo kwensiyini, imitha kufanele ibe kumodi ethi "Fast" lapho usampula inhlabamkhosi (isithombe 6).

Ukuhlola

Ukuze wenze ukuhlola kwe-siren, thola indawo evulekile ecishe ibe ngamafidi angu-300 ubude.Ngivamise ukusebenzisa izindawo zokupaka noma imigwaqo engasetshenziswa kancane evaleka kalula.Misa i-apparatus perpendicular to the roadway futhi ulinganise izinyawo ezingu-10 ngqo phambi kwe-siren.Lokhu kuzoba uphawu "0".Kusuka kumaki "0", abafundi bangahlola izimo ezimbalwa.

0-degree indlela:Indlela engu-0-degree ikala umsindo ngqo phambi kwenhlabamkhosi.Lokhu kuzolingisa imoto yomphakathi eshayela phambi kwezicishamlilo emgwaqeni ofanayo.Ukuze ulinganise indlela engu-0-degree, thatha izilinganiso ngokuqondile phambi kwe-siren.Izilinganiso kufanele zithathwe njalo ngamamitha angu-10 ukuze kuboniswe ukuthi izinga lokucindezela komsindo lehla kanjani njengoba ibanga elisuka ku-siren likhuphuka (isithombe 7).
Indlela ye-90-degree:Indlela ye-90-degree ikala umsindo eduze komgwaqo ophambanayo olingiswayo.Lesi simo sibonisa ivolumu ye-siren yemoto esondela ezintweni ezicisha umlilo ezimpambanweni zomgwaqo.Ukuze ulinganise indlela ye-90-degree, thatha izilinganiso uye kwesokunxele noma kwesokudla se-siren.Izilinganiso kufanele zithathwe njalo ngamamitha angu-10 ukuze kuboniswe ukuthi izinga lokucindezela komsindo lehla kanjani njengoba ibanga elisuka ku-siren likhuphuka (isithombe 8).
Inkambu yomsindo we-Siren:Ukulinganisa insimu yomsindo kuzohlinzeka ngesithombe sokuthi i-siren iphrojekthi evela kumshini womlilo.Izilinganiso zithathwa kugridi ngezikhawu eziyi-10-foot.Lokhu kuvumela abafundi ukuhlela inkundla yomsindo futhi bakhe isithombe esibonakalayo sokuqagela kwe-siren.
Izimpambanomgwaqo zangempela:Uma abezicishamlilo bengakwazi ukulawula ukuhamba kwezimoto ngokuphephile, ukufundwa kwengcindezi yomsindo kungathathwa ezimpambanweni zomgwaqo zangempela.Lokhu kuvumela abafundi ukuthi babone ukuthi inhlabamkhosi ivinjwe noma iboniswa kanjani izakhiwo, izihlahla, nezinye izinto ezisendleleni yenhlabamkhosi.

7 Ukulinganisa izinga lomfutho womsindo we-siren endleleni engu-0-degree.Izilinganiso zithathwa njalo ngamamitha ayi-10 kuye kumamitha angama-300.Lesi simo siyisibonelo sezixhobo zomlilo ezisondela emotweni yabantu abasuka ngemuva.

Uma izindawo zokulinganisa umsindo sezimakiwe, namathisela imitha yezinga lomsindo ku-tripod.I-tripod kufanele isethwe ibe ngamafidi angu-3.5, njengoba lokhu kuwubude obuvamile endlebeni yomshayeli.

Ngemva kokuqinisekisa ukuthi umhlanganyeli ngamunye ugqoke isivikelo sokuzwa futhi umile ngemva kwe-siren, cela ilungu ukuba livule inhlabamkhosi.Umjikelezo owodwa wokuya phezulu naphansi uzokwanela.Lapho inhlabamkhosi ikhala, abafundi kufanele bahlole ukufundwa kwedecibel kumitha yezinga lomsindo futhi barekhode ukufundwa.Phinda le nqubo kumaki wokulinganisa ngamunye.

Imishini eminingi yokucima umlilo ifakwe inhlabamkhosi eyimishini, inhlabamkhosi kagesi, nezimpondo zomoya.Umbuzo ojwayelekile abafundi abawubuzayo uthi, “Iyiphi inhlabamkhosi engcono?”Hlola isistimu ye-siren ngayinye ngayinye bese uzivivinya zonke ngesikhathi esisodwa.Ngokunokwenzeka, uhlelo ngalunye lwe-siren luzofana.

Khumbula ukuthi ama-siren amaningi azodinga ukuthi afike efasiteleni lomshayeli wemoto yomphakathi cishe ngo-110 dBA ukuze zingene kahle emotweni futhi zixwayise umshayeli.Kunini lapho uhlelo lwe-siren luwela ngaphansi kuka-110 dBA?Ingabe lokhu kwenzeka kude kangakanani nezisetshenziswa zomlilo?Ingabe imoto yabantu abavamile ingakwazi ukubona, isabele, futhi ishushuluze ime ukusuka kulelo phuzu?

Ukuyihlanganisa Ndawonye
