Complex geometry automotive muffler sound transmission loss measurement by experimental method and 1D simulation correlation

A muffler is a device to attenuate noise from the exhaust. The muffler performance determined by the acoustic performance is called sound transmission loss (STL). This paper aims to measure the STL experimentally and correlated with the 1D simulation result. STL was measured using the impedance tube...
