In recent years, automobile demand in the Indian market is growing up exponentially with more and more world-wide automobile manufacturers entering the Indian market. This has put tighter criteria in developing an automobile with the best overall performance at lower cost for the OEMs and auto component manufacturers to consider different aspects of a product during development stage. Noise, Vibration and Harshness (NVH) is one such product aspect, which is the most sensitive comfort requirement of an occupant and product quality cum cost to the manufacturer. With continuous improvements on noise reduction from the primary sources e.g. power-train and its sub-components of an automobile, the noise eminent from other sources like HVAC, wind, brakes, wipers etc. have become more perceivable to the in-vehicle occupants, especially for the car and SUV segment.
