The squeaky wheel gets the grease – that we all know. But it’s not just squeaks that concern product designers and engineers, but also grinding, buzzing, squealing, humming, and an endless list of strange sounds. Noise, vibration, and harshness (or NVH for short) is a common challenge in various industries, including automotive, aerospace, consumer goods, and more. In the simplest terms, NVH includes unwanted sounds and oscillation from metal panels, support structures, or other product components. Not only can NVH be unpleasant for consumers (such as a rattling sound coming from their vehicle), but it can hinder performance and lead to excess wear and tear on the product.
