“…Understanding the characteristics of this particular noise source is essential for the development of low-noise roads [37][38][39]. Other works investigate the sound quality of specific vehicle phenomena and components, such as closing car doors [40,41], engine noise [32,42], Heating, Ventilation, Air Conditioning (HVAC) systems [43], seat belts [44], and wind [45,46]. Some studies use linear regression modeling [47] to establish correlations between objective psychoacoustics metrics, such as pitch, roughness, volume, and others [48], and subjective sound quality metrics, which are often obtained from jury reviews [48].…”

Recently, the issue of sound quality inside vehicles has attracted interest from both researchers and industry alike due to health concerns and also to increase the appeal of vehicles to consumers. This work extends the analysis of interior acoustic noise inside a vehicle under several conditions by comparing measured power levels and two different models for acoustic noise, namely the Gaussian and the alpha-stable distributions. Noise samples were collected in a scenario with real traffic patterns using a measurement setup composed of a Raspberry Pi Board and a microphone strategically positioned. The analysis of the acquired data shows that the observed noise levels are higher when traffic conditions are good. Additionally, the interior noise presented considerable impulsiveness, which tends to be more severe when traffic is slower. Finally, our results suggest that noise sources related to the vehicle itself and its movement are the most relevant ones in the composition of the interior acoustic noise.

Noise isolation properties of the closure systems are important factors for the acoustic performance of vehicles. This study explains sound transmission through a door sealing system, and numerical methods analyze all acoustic responses’ parameters. A specific design of experiments (DoE) analysis is carried out to reveal the effects of each material along with the predefined geometric entities and their dimensions. Viscoelastic material parameters are included with full factorial designs for a particular geometry. Material optimization is implemented with the Taguchi method by incorporating noise factors. Optimization of the geometric entities is studied, and the best section shapes for acoustic performance are obtained. A robust optimization study is conducted by considering the uncontrollable noise factors. Consequently, the door closing efforts compromise the acoustic design to present an overall method with design constraints.

This study focuses on a certain vehicle model and analyzes the noise problem in the edge area of the front cover of the car through wind tunnel tests and Fluent numerical simulation software. Firstly, numerical calculations and analysis were conducted using fluid dynamics theory, acoustic theory, and other methods. Secondly, wind tunnel validation was conducted to analyze the impact mechanism of aerodynamic flow field on the noise of the front cover of automobiles. By comparing the simulation results of different design schemes, a simplified model was used to solve a type of method and solution for eliminating the edge noise of the front cover. Explored the mechanism of reducing noise at the front edge of the front cover of vehicles with through grille lights, studied the structure and position of the front grille light area, and applied it to eliminate wind noise in vehicle models. The simulation and experimental results show that the protruding diversion structure passing through the tail lights can effectively avoid the generation of wind noise at the front of the front cover, reduce the sound pressure value at the front cover, and reduce the noise to a maximum of 19 dB.
