Noise, Vibration, and Harshness (NVH) Solutions

NVH stands for Noise, Vibration, and Harshness, a critical trio of factors that influence how drivers and passengers perceive vehicle quality. Understanding NVH meaning is essential for automotive engineers aiming to create quieter, smoother, and more comfortable rides. NVH issues can stem from numerous sources, including engine operations, powertrain dynamics, road surfaces, and even aerodynamic flow. Through advanced NVH testing methods such as acoustic profiling, modal analysis, and vibration mapping, manufacturers can pinpoint problem areas and apply targeted solutions. Avery Dennison’s specialized vibration damping tapes and automotive adhesive technologies are engineered to meet these challenges, helping reduce noise and vibration transmission at the source. With a clear understanding of NVH meaning and a focus on precision materials, our solutions help OEMs meet customer expectations and maintain competitive performance standards.

Understanding and mitigating NVH (noise, vibration and harshness) starts with proper testing and analysis to uncover both audible and structural issues. NVH testing identifies the sources and characteristics of noise and vibration through techniques such as:

• Modal analysis
• Acoustic measurements
• On-road simulations
• Component-level testing

At Avery Dennison, we support OEMs and Tier suppliers with NVH challenges by providing data-driven material recommendations. Our adhesives and damping tapes are engineered based on extensive lab testing, application simulations, and customer feedback to deliver proven NVH performance.This ensures that the right adhesive or damping solution is applied to solve each specific NVH challenge.

Noise is any unwanted sound that reaches the driver and passengers. In powertrain systems, this can come from engine operations, road interactions, or mechanical connections. Reducing noise requires strategic material selection, thoughtful assembly techniques, and advanced adhesive solutions. Avery Dennison offers vibration damping tapes and engineered adhesives that effectively absorb and dissipate structure-borne sound energy, helping manufacturers achieve quieter, more refined vehicle cabins.

Harshness refers to the perception of abruptness or roughness in a vehicle’s ride quality. It’s not just about sound or movement, it’s about how vibrations and shocks are transmitted to passengers. In powertrain systems, managing harshness is essential to delivering the smooth, confident driving experience customers demand. Avery Dennison adhesives and damping tapes help soften harshness at the source, improving both subjective feel and measurable ride quality metrics.

At the heart of effective NVH control is material science innovation. Our vibration damping tapes are engineered with viscoelastic properties that convert vibrational energy into low-level heat, significantly reducing the transmission of noise and vibration. Coupled with our high-performance adhesives, these tapes bond securely to diverse substrates, withstand extreme automotive environments, and support lightweighting initiatives without compromising strength or durability. Whether you need a solution for bonding, thermal expansion control, or dynamic load damping, Avery Dennison's adhesive technologies are built to perform in the most demanding automotive NVH environments.

Effective powertrain NVH analysis is essential to identifying the sources of noise, vibration, and harshness, and designing solutions that eliminate them. At Avery Dennison, we work closely with OEMs and Tier suppliers, offering material recommendations based on rigorous testing, simulation data, and real-world performance metrics. Our deep experience in automotive NVH analysis ensures that every adhesive and tape solution we deliver not only meets but exceeds industry performance standards. With the continued evolution of vehicle design, controlling NVH and delivering optimal noise, vibration and harshness performance remains a key differentiator for automotive brands.
