description: The topic of the graduation thesis is "Optimization of the Noise Absorption Characteristics of the Automobile Exhaust System". This work is dedicated to investigating methods for reducing the noise of the exhaust system of a passenger car. The subject of the study is the calculation of sound pressure transmission loss and insertion loss in the exhaust system using the finite element method. During the study, a comparison of experimental data, analytical, and numerical solutions was conducted. The results of numerical calculations of the model problem coincide with experimental data with an error not exceeding 5%. Additionally, an analysis of transmission loss coefficients for various designs of mufflers and resonators using different sound-absorbing materials was conducted. Based on the conducted research, the initial design of the exhaust gas removal system for a passenger car was improved.
