Le Evolution of Sirens i Taavale Faalavelave Tutupu Faafuasei
Mai Origins i Modern Technology, o se Malaga i le Talafaasolopito o Sirens
Origins ma Early Evolution
le mua'i fa'alogo mo taavale afi faʻafuaseʻi aso i tua i le 19th senituri pe a fa'atupu leo fa'ailo e logo po'o masini masini. Falani enisinia eletise Gustave Trouve na atiina ae se tasi o leo muamua i le 1886 e faasilasila ai le taunuu lemu o ana vaa eletise. I le taimi Le Taua II o le Lalolagi, sa fa'aaogaina i Peretania e fa'ailoga osofa'iga a le ea. O nei faiga muamua sa faigata i nisi taimi ma fa'alagolago i le ea oomi, ma fa'aletonu ai le fa'aogaina i luga o ta'avale.
Le Vaitaimi Fa'aonaponei o Sirens
I le taimi atoa 20th senituri, sa matua'i fa'atuputupula'ia fa'alogo, fa'asolo mai masini masini i mea fa'aonaponei lomiga faaeletonika. O fa'aeletoroni fa'aeletoroni muamua na fa'ailoa mai i le 1970s, e fa'amoemoe e maua mai ni leo tuia i pu'e le mafaufau ma fa'amautinoa le saogalemu o tali ma tagata lautele. O nei sirens ua fa'atuputeleina fa'apitoa, fa'apipi'i ai sipika, fa'amalo, fa'aola leo mo tulaga eseese, ma pusa fa'atonutonu e mafai ai ona fa'atonutonu vave ma fetu'una'i. Sailiili faaonaponei tu'ufa'atasia leo eseese ma faiga moli fa'afuase'i e fa'ateleina le lelei ma le a'afiaga.
Pneumatic ma Electronic Sirens
fa'aili fa'a-pneumatic fa'aaoga tisiki fe'avea'i ma pu (choppers) e fa'alavelave ai le tafega o le ea, ma fa'atupu ai leo feliuliua'i o le ea fa'apipi'i ma seasea. O nei faiga e mafai ona faʻaaogaina le tele o le malosi ae ua sili atu ona lelei e ala i le faʻaogaina o le ea faʻamalosi. Sirens faaeletonika, i le isi itu, faʻaaoga taʻavale pei o oscillators, modulators, ma amplifiers e faʻapipiʻi ai leo filifilia, lea e taʻalo e ala i failauga fafo. O nei faiga e mafai ona fa'ata'ita'i i leo o fa'aili fa'ainisinia ma e masani ona fa'aoga fa'atasi ma fa'aumu pneumatic.
Le Evolution of Emergency Vehicle Lighting
E tutusa ma le talafaasolopito o sirens, fa'alavelave fa'afuase'i moli fa'afuase'i ua fa'atupuina fo'i le suiga tele. Muamua, o taavale faʻafuaseʻi na faʻaogaina moli mumu na faʻapipiʻi i luma poʻo le taualuga. I le taimi o le Taua Lona Lua a le Lalolagi i Siamani, na faʻaalia ai le lanu moana e fai ma lanu mo moli faʻafuaseʻi ona o lona faʻataʻapeʻapeina o meatotino, ma faʻaitiitia ai le vaʻaia e vaalele a le fili. I aso nei, moli taavale faʻafuaseʻi e matua'i eseese e fa'atatau i tulafono fa'alotoifale ma e masani ona fa'aoga fa'atasi ma faiga fa'aili e fa'aleleia atili ai le lelei ma tu'uina atu fa'aaliga va'aia ma fa'alogo.
