Description
Summary:The automotive industry is rapidly changing as electric vehicles (EVs) have gained share in the market, bringing new challenges to ensure passenger comfort through noise, vibration, and harshness (NVH) management. Automotive acoustics engineers employ a variety of materials to reduce NVH across the audible frequency spectrum. In general, these materials have been tailored to address vibrations related to internal combustion engines (ICE). For example, liquid applied sound damping (LASD) coatings are widely employed to reduce structural vibrations due to their ease of application and light weight. LASD coatings are typically applied to the vehicle body to reduce structural vibrations at frequencies
