Abstract: Customer comfort in terms of NVH is a tangible and intangible effect. NVH is directly and indirectly connected to the psychoacoustics of human beings and their lives. As part of the advanced NVH analysis, the effects of noise have been studied in terms of psychoacoustic parameters, including loudness, sharpness, roughness, fluctuation strength, and tonality. A car door or door assembly is a crucial component of a car or vehicle. The door is softly and flexibly connected to the main body of the vehicle, protecting passengers from weather effects and accidental impacts. Due to the inherent flexibility of the door, its flexible connections, sharp transient closing, and vehicle operational excitations, the door assembly is a primary source of noise and vibration in vehicles. It is a prime requirement to understand the NVH (Noise, Vibration, and Harshness) effect of doors on cars, their analysis, and ways to improve them. To understand the current status of the basic and advanced NVH analysis of the door, an extensive survey and detailed study were conducted. The primary focus is given to technical papers published related to noise/sound quality (SQ) over the last two decades, i.e., between 1999 and 2022. A total of 31 technical papers were scrutinised and summarised into different categories. Broadly divided into: the number of papers published each year, the Number of papers on types of SQ assessment, and the number of documents discussing SQ parameters. This study of the 31 papers published between 1999 and 2022 has provided a ready reference for the work done on sound quality, primarily related to vehicle and door NVH. The total number of parameters considered by different researchers and the approaches used by them to assess the psychoacoustic parameters of noise/ sound. Ultimately, these parameters and their levels help determine the quality of the sound produced or generated by any source.
