Abstract

This study explores the acoustic performance of a single-expansion-chamber reactive muffler through theoretical, numerical, and experimental methods, focusing on transmission loss as a measure of noise attenuation. Theoretical analysis employs the Transfer Matrix Method (TMM) to model the sound wave behavior by incorporating geometric parameters and fluid acoustic properties. Numerical simulations using the Finite Element Method (FEM) provide insights into the sound pressure distribution and validate theoretical predictions. Experimental testing in a controlled laboratory environment measures the muffler transmission loss and offers a practical benchmark for comparison. The results revealed a strong correlation between the theoretical, numerical, and experimental data, demonstrating the reliability of these methods. This study identifies critical design parameters that influence noise attenuation and provides guidelines for optimizing muffler performance in automotive applications. This integrated approach offers a comprehensive framework for analyzing and improving the acoustic efficiency of reactive mufflers.
