Demand for passenger vehicles continues to expand in emerging markets, and consumers are putting greater importance on maximizing comfort to create the best overall driving experience.
Noises created from a vehicle’s structure and airborne noises may cause passenger discomfort or annoyance, but new technologies and advances in noise, vibration and harshness (NVH) materials for sound dampening are providing options to eliminate extra noise from in-cabin vibrations and friction.
NVH materials – acoustic devices generally classified as sound-absorbing materials, sound-barrier materials, and sound dampening materials – are used both inside and outside a vehicle to eliminate noise. Liquid-applied spray dampers, liquid-applied sound dampers, liquid-applied sound deadener, and liquid applied spray deadener are all different terminologies for NVH materials used for the same process – applying a layer of material to dampen sound transmission.
Creating a heavy layer – the thicker the layer, the less sound that can come through – will diminish or eliminate noise. These materials, however, are not only used during the collision repair process, but some vehicle owners are also requesting additional sound dampening following the installation of aftermarket accessories and systems, such as an upgraded stereo.
Autobody shops should embrace this as an opportunity. By providing the latest in sound dampening technology options, shops can help work toward complete customer satisfaction while helping out their own businesses.
Ultimately, the goal for any repair job is to structurally and aesthetically restore a damaged vehicle to its pre-accident condition by fulfilling both OEM guidelines and safety requirements – and having a satisfied customer.
