Impact hammer testing and powertrain NVH testing are the two major opportunities in the NVH testing market. In the impact hammer test, the device to be analyzed is kept on a vibration table on which real conditions are simulated. The impact hammer mechanically sends controlled impulses at several desired points on the device, while sensors capture the ensuing vibration in the form of data. This helps in determining unwanted frequencies of noise and vibration along with their source locations. Through such a study, an engineer is able to recommend appropriate design improvements or modifications so as to minimize undesirable noise and vibration levels. This then enhances product quality and durability.

Correspondingly, the powertrain NVH test primarily focuses on the assessment and refining the quality of powertrain systems within automotive. It detects potential areas and design changes, considering noise and vibration reduction, in order to ensure better performance of the powertrain system concerning efficiency and reliability. The NVH test methodology solutions will see rising demand due to growing vehicle production worldwide, including impact hammer testing and powertrain assessment. The growth in vehicle production, in return, requires the usage of advanced NVH testing technologies that guarantee high-quality and reliable vehicle performance. Hence, the trend acts like a driving factor for market growth and innovation in the sector.
