How Are Automakers Reducing Vehicle Weight Through Automotive NVH Materials?

Agents or substances capable of blocking or reducing the noise, vibrations, and harshness (NVH) originating from automobile parts, such as brake and accelerator pedals, engine boxes, armrests, and steering wheels, are known as automotive NVH materials. NVH is usually sensed at the engine box, steering wheel, armrests, pedals, and floor of the vehicle. At present, bio-based-polyurethane is gaining traction as an NVH material due to the surging focus of the automobile industry on pollution control and environment preservation.

The adoption of NVH materials in automobiles helps in reducing the overall vehicle weight, owing to which a surge in lightweight vehicle production and adoption will drive the automotive NVH materials market at a CAGR of 7.2% during the forecast period. The market was valued at $7,579.8 million in 2017, and it is expected to generate $11,467.5 million revenue by 2023. As lightweight vehicles help in reducing emissions, conserving energy, and decreasing wear and tear on brakes and tires, automakers across the world are using NVH materials in abundance.

The application segment of the automotive NVH materials market is classified into insulation, vibration damping, and sound absorption. Under this segment, the sound absorption category is expected to demonstrate the fastest growth throughout the forecast period due to the soaring number of complaints of unwanted noise from vehicle parts. For instance, according to the European Union (EU), approximately 40% of the EU populace is exposed to road traffic noise at levels exceeding 55 decibels.

According to P&S Intelligence, Asia-Pacific (APAC) dominated the automotive NVH materials market during the historical period (2013–2017) owing to the rising automobile production and sale in developing countries, such as China and India. Whereas, North America held the second position in the market in 2017 owing to the soaring disposable income of people and mounting investments being made in the automotive sector of the region. Automobile manufacturers in this region are largely focusing on improving the overall ride quality and reducing NVH.

Therefore, the booming demand for lightweight vehicles and rising focus of automakers on reducing cabin sounds, engine vibrations, and suspension feedback of vehicles will create a huge requirement for NVH materials.
