Hyundai IONIQ 5 Soundproofing Review: Road Noise Reduction

Why Soundproofing Matters for the Hyundai IONIQ 5

As electric vehicles like the Hyundai IONIQ 5 become more common, the absence of engine noise makes other sounds more noticeable. Road noise, wind noise, and sounds from surrounding traffic can intrude into the cabin, diminishing the quiet EV experience. This review details a soundproofing installation focused on the doors and wheel arches of an IONIQ 5, aiming to significantly reduce these intrusive noises and enhance overall cabin comfort. The goal is to create a more serene driving environment, allowing occupants to better enjoy the inherent quietness of their electric vehicle.

Wheel Arch Soundproofing: Tackling Road Noise at the Source

Road noise originating from the tires and the road surface is a primary concern for many drivers, especially in EVs where it's more apparent. The wheel arches are a direct pathway for this noise to enter the cabin. The installation process begins with removing the wheel arch covers. A sound-damping mat is then meticulously applied to the metal paneling to suppress vibrations and minor rattles caused by road impacts. This initial step is crucial for reducing the transmission of high-frequency vibrations through the car's structure.

Following the vibration damping, a thick sound-absorbing material, specifically 3M Thinsulate, is applied to the interior of the wheel arch covers. This material is securely attached using ultrasonic welding, ensuring a durable bond that won't loosen or create new noises over time. This comprehensive approach to the wheel arches significantly diminishes the noise that travels up from the road, leading to a noticeably quieter ride.

Door Soundproofing: Blocking External Intrusions

Door soundproofing acts like a barrier against external sounds, such as noises from adjacent vehicles or wind noise that can enter through door seals. The process involves removing the inner door panels to access the metal frame. A high-quality sound-damping mat, often used in car audio upgrades, is applied to the door's inner skin to reduce panel resonance and vibrations. This not only dampens noise but also contributes to a more solid feel for the doors.

Additional damping is applied to the door trim where factory insulation is often minimal, further reducing residual vibrations. The original sound-absorbing materials are then reinstalled, often secured with ultrasonic welding to ensure a factory-like fit and prevent any new rattles. Finally, meticulous attention is paid to the door trim clips, with sound-absorbing material applied to prevent any noise from loose fittings. All components are reassembled to their original state, leaving no visible signs of the installation.

Installation Process and Expected Results

The entire soundproofing process for the doors and wheel arches of a Hyundai IONIQ 5 typically takes approximately 4 to 6 hours. The cost for this type of comprehensive soundproofing service in Korea generally ranges from 400,000 to 700,000 KRW (approximately $300 to $500 USD), depending on the specific materials used and the extent of the coverage. After installation, drivers can expect a significant reduction in road noise and external sound intrusion, leading to a more refined and peaceful driving experience. The durability of the materials used ensures long-lasting benefits, with minimal maintenance required beyond standard vehicle cleaning.
