Road Noise
<p>Road Noise is a collection of fifty poems addressing the relationship between history and place. Specifically, the collection engages ways in which places become artifacts and ways in which artifacts become places in which to dwell, through forms representative of history and tradition as relics …

Analyzing Skid Resistance and Tire/Road Noise on Porous Pavement Using Numerical Modeling
Skid resistance and tire/road noise are major concerns in pavement functional performance. Porous pavement enhances skid resistance through inner drainage and reduces tire/road noise through acoustic absorption. This study attempts to explore the development of numerical models in predicting skid …

Implications of nonlinear suspension behaviour for feedforward control of road noise in cars
… to the problem of low frequency structure-borne road noise in cars. Feedforward control of road noise is predominantly limited by the difficulty of finding reference signals that are highly coherent with the sound in the cabin. One factor that could restrict the coherence of the reference …

Active noise control in a luxury vehicle
Structure-borne road noise is a critical sound attribute for the overall Noise Vibration& Harshness (NVH) performance of modern luxury vehicles. Currentpassive NVH solutions require structural design modifications, in order to controllow frequency sources that cause structure-borne noise. Active …

Characterization of Structure-Borne Tire Noise Using Virtual Sensing
… have been made to the vehicle (reduced engine noise, reducedaerodynamic related NVH), have resulted in tire road noise as the dominant source of thevehicle interior noise. Generally, vehicle interior noise has two main sources, 1) travellinglow frequency excitation below 800 Hz from road …

Active control of automobile cabin noise with conventional and advanced speakers
… fields, particularly in automobiles. Both Active Noise Control (ANC) and Active Structural Acoustic Control (ASAC) techniques are being applied to problems stemming from power train noise and road noise (noise due to the interaction of the tires with the surface of the road). Due to the low …

Active control of an automobile suspension system for reduction of vibration and noise
A new method for controlling road noise transmitted through the suspension system of an automobile was developed, using a Lincoln LS automobile as the target vehicle. In this vehicle, road surface roughness generates vibrations that are transmitted into the automobile primary through a single …

Enhancing Network-Level Pavement Macrotexture Assessment
… splash and spray, ambient and in-vehicle noise, tire wear, and rolling resistance. While devices and general guidance exist to measure macrotexture, the wide-scale collection and use of macrotexture is neither mandated nor is it typically employed in the United States. This work seeks to …

A Novel Framework for Modeling Reconfigurable Dynamic Systems
… achieving superior ride comfort and minimizing noise and vibration levels is paramount. This is especially critical for electric vehicles (EVs), where predicting road noise presents unique challenges due to the added weight of battery packs. This thesis introduces a Generalized technique to …

Structure-Borne Vehicle Interior Noise Estimation Using Accelerometer Based Intelligent Tires in Passenger Vehicles
… are becoming quieter than ever before. But noise levels remain a significant concern for both passengers and automotive manufacturers. The vehicle's interior noise can affect the overall driving experience and even the safety of the driver and the passengers. The two main sources of vehicle …
