【 摘 要 】
Among the other noise problems, the low-frequency booming noise is the most annoying one. The booming noise significantly reduces the total quality perception of the brand. In this study, the contributions of secondary components to the booming noise are investigated. The general aspects of the problem are given for the sake of completeness. The causes of low-frequency booming noise are explained. The widely accepted procedure for the booming noise is discussed through the results of a case study, where an automobile equipped with a diesel engine is studied. In the case study, two different secondary components that cause booming noise are identified experimentally. It is proposed to improve the widely accepted procedure by adding an extra step for the secondary components. In some cases, the secondary components are the main causes of the unforeseen noise and vibration problems, as the current study reveals.
