Ngati galimoto wamba ikuyenda 45 mph, zimatengera dalaivala pafupifupi mapazi 195 kuti azindikire, kuchitapo kanthu, ndikudumphira kuti ayime pamsewu wowuma.kamodzi dalaivala amamva siren.Ngati dalaivala amva kulira kwa siren pamtunda wa mamita 80 kuchokera pa mphambano ndipo zimatengera mamita 200 kuti ayime, dalaivala sadzakhala ndi nthawi yoti ayambe kuyenda ngati zida zozimitsira moto zitatulukira pampitawo.Lingaliro ili likufotokoza kufunikira koyima kokwanira pamphambano zanjira yolakwika.

Ophunzira ambiri amafunsa kuti, “Bwanji osamveketsa sirenyo?”Chifukwa chomwe ma siren sangathe kumveketsa kwambiri ndikuti siren yokweza kwambiri imatha kuyambitsa vuto lakumva kwa ozimitsa moto ndikusokoneza anthu ozungulira mpaka kufika pamlingo wosavomerezeka.Pazifukwa izi, kuchuluka kwa siren yagalimoto yadzidzidzi kuyenera kuchepetsedwa.

Maphunziro a M'manja

Ndikofunikira kuti alangizi a EVOC apereke maphunziro apamanja kuti alimbikitse lingaliro lazoletsa za siren.Maphunzirowa atha kutheka pogwiritsa ntchito mita yolumikizira mawu, ma tripod, ndi siren yagalimoto yadzidzidzi.

Sound Level Meter:Miyero ya mlingo wamawu ikhoza kugulidwa motsika mtengo kuchokera ku sitolo yosungiramo chitetezo.Pali mitundu yosiyanasiyana yamamita amtundu wa mawu, ndipo mtundu uliwonse umakhala pamtengo.Mamita a Class 1 ndi olondola, koma mita ya Class 2 ndiyokwanira ngati chida chophunzitsira (chithunzi 1).
Sound Level Meter Calibrator:Ndikofunikira kuwongolera mita ya mlingo wa mawu musanayambe maphunziro aliwonse pogwiritsa ntchito chowongolera mawu.Ngakhale calibrator ikhoza kukhala yokwera mtengo, idzaonetsetsa kuti miyeso ya mawu ndi yolondola (chithunzi 2).
Tripod:Mamita ambiri amawu amawu amatha kumangirizidwa ku katatu ya kamera.Ma tripod amalola wophunzira kuyika mita ya mlingo wa mawu pamalo okhazikika ndi kubwerera pamalo otetezeka pamene siren ikuyezedwa.Osayima m'malo omveka a siren kuti mutenge miyeso.Tetezani makutu anu.
Chitetezo:Kumbukirani kuwonetsetsa kuti wophunzira aliyense wavala zodzitetezera kumakutu.Komanso, kumbukirani kuwonetsetsa kuti aliyense wayimirira KUseri kwa sirenyo pamene siren ikuyesedwa.Ophunzira ayenera kupita ku sitepe yakumbuyo kwa zida kuti awateteze kuti asamveke kwambiri.Osayima kutsogolo kwa siren!

dBA vs. dBC:Mamita amawu amawu nthawi zambiri amakhala ndi ma decibel awiri: dBA ndi dBC.Kuyika kwa dBA kapena dBC kudzatsimikizira momwe masefa a mita amamvekera.Pochita masewera olimbitsa thupi, gwiritsani ntchito makonzedwe a dBA popeza izi zimafanizira bwino momwe khutu la munthu limamvera phokoso (chithunzi 3).
Pamwamba/pansi:Kuyika kwina kofala pa mita ya mlingo wa mawu ndi "mkulu / wotsika".Kuyika "kwapamwamba / kutsika" kumatengera kuchuluka kwa mawu oyezera.Pamene mita ili pafupi ndi siren, gwiritsani ntchito "mkulu".Pamene mita imasunthidwa kutali ndi siren, sinthani mitayo kukhala "yotsika" yokhazikika.Onani malangizo a wopanga kuti mudziwe kutalika koyenera/kutsika kwa mita yanu (chithunzi 4).
Kusintha kwa "Max":Ma Sirens "amasesa" m'mwamba ndi pansi, zomwe zipangitsa kuti kuwerenga kwa decibel pazenera kusinthe nthawi zonse.Kuyika kwa "max" kumapangitsa kuwerenga kwa siren kokweza kwambiri panthawi ya mayeso.Izi zimapangitsa kuti zikhale zosavuta kulemba deta.M'moyo weniweni, kuchuluka kwamphamvu kwa siren kumangogunda kuwerengera kwakukulu kumeneku nthawi ndi nthawi, kutengera momwe siren imasesa m'mwamba ndi pansi.Onetsetsani kuti ophunzira amvetsetsa kuti kuwerenga "kwambiri" ndi njira yabwino kwambiri kwa wogwiritsa ntchito zida zozimitsa moto (chithunzi 5).
Mofulumira/pang'onopang'ono:Zosinthazi ziwonetsa momwe mita ya mlingo wa mawu imatengera liwiro la mawuwo.Chifukwa cha kukwera msanga ndi kugwa kwa siren, mita iyenera kukhala mu "Fast" mode poyesa siren (chithunzi 6).
