NVH stands for noise, vibration, and harshness. In the industry, this term is used to locate the potential source of a noise, vibration or shake and it covers the whole range of perception of vibration from hearing to feeling. Noise can be described as the sound which is undesirable; vibration can be understood as the oscillation which can be felt as opposed to being heard; and harshness can be illustrated as the severity and discomfort one can feel followed by undesirable sound or/ and vibration, arising particularly from short length events. On account of haphazard transportation, manufacturing and communication activities, sound and vibration produce a negative impact on the environment. The safety of vehicles and the level of noise at home and work are negatively influenced. Therefore, company resort to the NVH testing as a method to reduce noise. Noise, vibration and harshness (NVH) testing involve employing a whole vehicle or an element to vibrations at various frequencies, as a method to determine isolating buzzes, squeaks, mode shapes and rattles. The test results are fed into a computer for modal analysis. Full-vehicle NVH tests usually employ “4-poster” test systems and environmental chambers for precisely recreating real-world service conditions within the test research labs.
The automobiles are extensively tested to ensure that they can withstand the mechanical shocks, and their safety equipment such as airbags are tested to ensure that they utilize vibration transducers as critical sensors that can indicate danger and trigger appropriate action. Moreover, instances such as dishwasher, planes flying overhead or use of lawnmowers can also impact the NVH level in a society. The NVH reduction and effective sound quality testing have become the primary objectives for the manufacturers to differentiate one’s product from the competition. Moreover, the government has also imposed stringent regulations to curb the noise pollution. And, this adoption of stringent regulations by the government to curb noise pollution has become one of the primary elements which drive the growth of NVH Testing market across the globe. Furthermore, the growing demand for automotive and car infotainment system also impact the market growth positively. However, the increasing demand for second hand and rental NVH testing equipment can hamper the market growth.
The efficient and accurate NVH tests enable the vehicle manufacturers to optimize their design and development processes of the vehicles. There are many people employed who devote their services in order to curb the harmful effects of noise, sound and vibration. Geographically, North America will drive the market growth of NVH Testing across the globe on account of the presence of major automotive, aerospace and defence companies along with the presence of prominent NVH testing solutions providers
