Nayoung Lee (HYUNDAI MOBIS)10/09/2026, 09:00A01 Active Control of Sound and Vibration
This study explores the effect of utilizing the Multiple Coherence Function (MCF) analyzation in optimizing reference sensors and installment positions of Active Road Noise Cancellation (ARNC) system. The ARNC system broadly consists of speakers, microphones, sensors which provide reference of noise source and electronic controller which filters the unwanted noise through algorithm. ARNC is...

Giovanni Battista Pirro (Virtual Vehicle Research / KU Leuven)10/09/2026, 09:00A01 Active Control of Sound and Vibration
Acoustic perception can complement vision-centric sensing in autonomous driving by providing safety-critical cues such as emergency-vehicle sirens and horns, which often include strong tonal components and distinctive modulation patterns. Acoustic sensing for autonomous vehicles spans event detection/classification, separation, localization, and tracking. This work focuses on sound source...

In the automotive domain, flat-panel loudspeakers (FPLs) offer a compelling alternative to conventional electrodynamic transducers due to their reduced form factor and lower moving mass, which facilitate integration into interior trim and improve overall power consumption. However, the acoustic performance of these systems depends on coupled design parameters. The most relevant include surface...

Joowon Park (Hyundai Mobis Co., Ltd.)10/09/2026, 09:00A01 Active Control of Sound and Vibration
In automotive active noise control (ANC), the secondary pathโthe transfer from the loudspeaker to the error microphoneโhas a strong effect on control performance. In real driving, the number of occupants changes often, but its impact on the secondary path has not been studied much through experiments. This paper tests how occupant count changes the secondary-path magnitude and phase in a...

Dongmin Yang (Hyundai Mobis Co., Ltd.)10/09/2026, 09:00A01 Active Control of Sound and Vibration
This paper proposes a strategy for an FxLMS-based automotive active road noise control (ARNC) that accounts for redundancy among reference signals and is suitable for application in production vehicles. Usually, multiple reference signals of vehicles with ARNC system are measured by accelerometers mounted at each wheel hub. However, due to the structural characteristics of vehicles, these...

Shinichi Suganuma (Nissan Motor Co., Ltd.)10/09/2026, 16:20A01 Active Control of Sound and Vibration
In hybrid vehicles, the contrast between engineโoff and engineโon states makes engine noise noticeable, and in series hybrid vehicles the engine is used only for power generation and does not need to match the driving state, so engine sound can become annoying. To improve engine sound quality, factors contributing to engineโnoise perception must be quantitatively identified.Using onโroad data...

Laurence Wilmshurst (ISVR, University of Southampton)10/09/2026, 16:40A01 Active Control of Sound and Vibration
Multi-channel road noise cancellation (RNC) systems in electric vehicles increasingly rely on large arrays of reference signals that generate coloured and highly correlated reference signals. These characteristics result in poorly conditioned co-variance matrices, leading to slow convergence when using adaptive feed-forward algorithms such as FX-LMS. This paper investigates the use of a...

Alessandro Travaglini (HARMAN BECKER Automotive Systems GmbH)10/09/2026, 17:00A01 Active Control of Sound and Vibration
Accurate spatial audio reproduction is increasingly important in automotive applications such as navigation guidance, advanced driver-assistance systems, and immersive entertainment. This study compares sound source localization performance in a vehicle cabin and an ITU-R BS.775-4 compliant multichannel reference listening room to assess whether the latter can serve as a suitable environment...

Dongin Kim (University of Southampton)10/09/2026, 17:20A01 Active Control of Sound and Vibration
Higher-Order Ambisonics (HOA) is a widely used technique for sound field auralization; however, it presents inherent limitations, particularly in the trade-off between the number of transducers (microphones and loudspeakers) and the achievable timbral and spatial accuracy of the reproduced sound field.More recently, alternative approaches for the acquisition and reproduction of spatial room...

This study examines the impact of real-time listener position tracking on binaural audio reproduction using loudspeakers in automotive settings. The system employs headrest-integrated speakers in combination with crosstalk cancellation (CTC), a technique known for its high sensitivity to listener position. Even minor head movements can lead to substantial performance degradation, particularly...
