Tire-pavement interaction noise (TPIN) has become critical in vehicle acoustics as electric vehicles proliferate. Among TPIN mechanisms, tire cavity resonance produces prominent in-cabin noise peaks. Current mitigation strategies use porous foam liners on inner tire walls, but these face limitations: constrained space, environmental degradation, and insufficient frequency tunability. This study introduces acoustic metasurfaces mounted on tire rims as an alternative. Leveraging reflective and local resonant properties, metasurfaces precisely manipulate the low frequency TPIN below 500 Hz. Numerical analysis using COMSOL Multiphysics demonstrates that metasurfaces achieve substantial sound pressure reduction and higher transmission loss than porous materials, establishing them as promising technology for lightweight, frequency-tunable TPIN control.
Tire cavity resonance is a dominant TPIN source in EVs, requiring targeted mitigation at low frequencies below 500 Hz.
Despite widespread use, 2025 Consumer Reports testing found foam liners deliver no discernible noise reduction, underscoring need for new solutions.
Paradigm shift: controlling sound transmission through rim-mounted metasurfaces rather than modifying tire design, preserving tire performance while achieving superior noise reduction.
This approach opens new pathways for tire-vehicle co-design, enabling acoustic optimization independent of tire structural and dynamic requirements.
