Saxanka xumbo aluminiumka ah ee xiran ayaa lagu sameeyaa saxan wax ku ool ah oo wax ku ool ah ka dib daaweynta daloolinta (φ2mm godka, heerka daloolinta 1 ~ 3%), kaas oo leh waxqabadka nuugista dhawaaqa ugu fiican, iyo heerka nuugista dhawaaqa wuxuu gaari karaa 60% ~ 90%. Sababtoo ah dusha maaddadan ma laha wax diyaarad ah, waxay leedahay shaqo nuugista maqalka oo aad u fiican, isla mar ahaantaana waxay dalooshay Helmholtz nuugista resonance function nuugista codka si loo hubiyo heerka nuugista codka sare. Intaa waxaa dheer, jawiga qoyan, qalabka caadiga ah ee nuugaya dhawaaqa ayaa nuugaya qoyaanka iyo ballaarinta, iyo isugeynta dhawaaqa nuugista si weyn ayaa loo yareeyaa, halka walxaha aluminiumku aanu nuugin qoyaanka, iyo heerka nuugista codka aan la dhimin.
Marka dhumucda lakabka hawadu uu ka kordho 0mm ilaa 90mm, inta jeer ee ugu weyn ee nuugista codka ayaa hoos u dhacaysa 2000Hz ilaa 300Hz. Marka dhumucda lakabka hawadu uu yahay 10, 30, 60, 90mm, inta jeer ee ugu weyn ee heerka nuugista dhawaaqu waa qiyaastii 1000Hz, 500Hz, 400Hz, 300Hz siday u kala horreeyaan. Sida laga soo xigtay qaybinta soo noqnoqoshada qaylada design naqshadaynta heerka nuugista dhawaaqa saxan ka dambeeya dhumucda lakabka hawada. Inta jeer ee ugu weyn ee buuqa ka dhasha baabuurta ee wadada weyn, tunnel hoose ee webiga iyo tunnel submarine waa ku dhawaad ​​400Hz, taas oo ah qaylada soo noqnoqda hooseeya, sidaa darteed lakabka hawada ee 60mm qaro weyn ayaa la dhigay gadaashiisa saxan aluminium acoustic xumbo ee xannibaad dhawaaqa weyn, hoose webiga iyo gidaarka acoustic ee tunnel tunnel-ka badda hoostiisa mara, kaas oo leh saameyn wanaagsan oo hoos u dhigista qaylada. Sawaxanka jidka tareenada waa qaylada dhexdhexaadka ah ee soo noqnoqda ee ka sarreeya 1000Hz, iyo 20mm lakabka hawo qaro weyn ayaa la dhigayaa gadaashiisa xumbo aluminium ah oo sanqadh nuugaya, kaas oo leh saameyn yaraynta dhawaaqa wanaagsan.
