Mahimman Abubuwan Acoustics: Ka'idodin Yada Sauti

Sauti yana tafiya a cikin raƙuman ruwa waɗanda ke watsa makamashi ta iska da tsari. Masu samar da dizal suna samar da hayaniya ta hanyoyi da yawa: konewar injin, motsi na inji, tsarin shaye-shaye, da shan iska. Ƙungiyar ma'auni, decibels (dBA), tana ƙididdige matakan matsi na sauti logarithmically, ma'ana kowane haɓaka 10 dBA yana wakiltar ninki biyu na tsinkayen ƙara.

Hanyar injiniyarmu tana rage hayaniya ta hanyoyi guda uku:
