“…This contribution is most likely from roadway noise, both structure-borne and airborne noise (band 10–2000 Hz). 27 From midnight to early morning, no clear roadway noise is recorded, with the exception of some noise at around 03:00 h, when many bars close and people drive back home. Regular traffic starts again around 07:00 h [Fig.…”

Confinement due to the COVID-19 pandemic drastically reduced human activities. Underwater soundscape variations are discussed in this study, comparing a typical and confinement day in a coastal lagoon near a popular tourist city in Mexico. Recording devices were located at 2 m in depth and 430 m away from the main promenade—a two-way avenue for light vehicle traffic—where main tourist infrastructure is located. The nearby marine environment is habitat to birds and dolphins as well as fish and invertebrates of commercial importance. Medium and small boats usually transit the area. The main underwater sound level reduction was measured at low frequencies (10–2000 Hz) because of the decrease in roadway noise. Vessel traffic also decreased by almost three quarters, although the level reduction due to this source was less noticeable. As typical day levels in the roadway noise band can potentially mask fish sounds and affect other low frequency noise-sensitive marine taxa, this study suggests that comprehensive noise analysis in coastal marine environments should consider the contribution from nearby land sources.

“…Fundamentally, passengers hear noises through the pressure waves transmitted to their ear drums in the air in the cabin compartment. However, these pressure waves can be induced in two fundamentally different ways, which is the classical distinction between noise sources in a vehicle [2]:…”

“…Figure 1. : Frequency range of structure-borne and airborne noise components [2] Both noise sources lead to the vibration of the chassis elements (such as body panels, windshields, trim elements, etc.) and this vibrational energy transforms to pressure waves inside the passenger compartment, which then excite the eardrum of the passengers.…”

Recent trends in vehicle engineering require manufacturers to develop products with highly refined noise, vibration and harshness levels. The use of trim elements, which can be described as Poroelastic materials (PEM), are key to achieve quiet interiors. Finite Element Methods (FEM) provide established solutions to simple acoustic problems. However, the inclusion of poroelastic materials, especially at higher frequencies, proves to be a difficult issue to overcome. The goal of this paper was to summarize the state-of-the-art solutions to acoustic challenges involving FEM-PEM simulation methods. This involves investigation of measurement and simulation campaigns both on industrial and fundamental academic research levels.

“…As the quality of life improves, consumers increasingly demand enhanced comfort features in automobiles, particularly concerning the sound quality within the driver’s cabin [ 8 ]. As a result, to mitigate the harmful effects of noise on drivers and passengers, there is a growing emphasis on noise reduction measures [ 9 , 10 ].…”

Tire–road noise deteriorates the sound quality of a vehicle’s interior and affects the driving safety and comfort. Obtaining low interior noise is a challenge for passenger car manufacturers. Traditional passive noise control (PNC) is efficient for canceling high frequency noise but not useful for low frequency noise, while active noise control (ANC), according to the residual error signal, can generate an anti-noise signal to reduce the original noise. Most research has focused on improving the control effect for a feedforward ANC system. However, this paper emphasizes a feedback ANC system based on a signal microphone sensor. There are two main contributions in this study to improve automotive cabin sound comfort. One is that the algorithm of the feedback ANC system using a single microphone sensor without a reference noise signal is proposed based on the Filtered-x Least Mean Square method. The other is that the algorithm applies additive random noise online to estimate the secondary path model. A simulation was implemented based on measured real road noise data, and the simulation results indicate that the proposed feedback ANC system with the single microphone sensor can effectively attenuate road noise. This study shows the feasibility of applying a feedback ANC system in automobiles to increase the cabin sound quality.
