Isithuthi esiqhuba endleleni siya kuba nengxolo enkulu ngaphakathi kwindawo yabakhweli kwisithuthi.Le ngxolo yaziwa ngokuba "yingxolo engqongileyo."Ingxolo ye-Ambient iya kuxhomekeka kwizinto ezininzi, kuquka ingxolo evela kwi-injini, unomathotholo, inkqubo ye-HVAC, kunye nokukhuhlana kwamatayara aqengqeleka kumphezulu wendlela.Ingxolo yendawo ngaphakathi kwisithuthi somkhweli esihamba iimayile ezingama-45 ngeyure (mph) ikholisa ukuba malunga nama-65 eedecibels (dB).

Yei-sirenukuze iviwe ngokufanelekileyo ngumqhubi ongekho mkhosini, kufuneka ingene kumzimba wesithuthi kwaye ibe phezulu kunengxolo ekhoyo.Uphononongo lubonise ukubai-sireninqanaba kufuneka linyuke malunga ne-10 dB ngaphezulu kwengxolo yendawo engqongileyo ukophula ngokufanelekileyo uzinzo lomqhubi.Ukuba ingxolo engaphakathi kwisithuthi soluntu ngama-65 dB, i-siren kufuneka inyuke iye kuma-75 dB.

Ubume besithuthi sanamhlanje siyilelwe ukugcina isandi OUT.Ngokomyinge, isithuthi sanamhlanje siya kuvala malunga ne-30-40 decibels yengxolo ekungeneni kwindawo yabakhweli besithuthi.Oku kwaziwa ngokuba "yilahleko yokufaka."Ukuba umqhubi woluntu ufuna i-decibels ezingama-75i-sireningxolo yokusabela, ii-sirenkufuneka ifike ngaphandle kwefestile yomqhubi malunga ne-110 decibels, ithatha i-avareji yokufaka ilahleko ye-35 dB.

2 Isixhobo sokulinganisa iimitha zomgangatho wesandi.

Ingxaki

Uninziiisayirenizilinganiswe malunga ne-124 dB xa zilinganisa iinyawo ezili-10 phambi kwei-siren.Njengoko umgama osuka kwi-siren uphinda kabini, uxinzelelo lwesandi se-siren luya kuhla malunga ne-6 dB.Le ngcamango yaziwa ngokuba "ngumthetho ophambeneyo wesikwere."

Kubalulekile ukuqonda ukuba oku kwehla kwe-6-dB kwinqanaba loxinzelelo lwesandi kuthatha ukuba umgama olinganisiweyo uphambi ngqo.i-siren.Xa imilinganiselo yoxinzelelo lwesandi ithathwa kwi-angle ye-90-degree ukusuka kwi-i-siren, ukuhla kwe-6-dB kunokubaluleka ngakumbi.Uphononongo lubonise ukuba ukunciphisa kwinqanaba loxinzelelo lwesandi kwi-intersection ye-90-degree ingaba phezulu njenge-11 dB.Le yingongoma ebalulekileyo yokufundisa, njengoko ukungqubana kweendlela kwenzeka xa izixhobo zomlilo kunye nesithuthi soluntu sisondela enye kwenye nge-angle ye-90-degree.
