Everyone wants a quiet ride, so noise control is a must in the automotive industry. Noise vibration and harshness, or NVH, is a term used to describe sounds such as squeaks, rattles, knocks and the like associated with mechanical devices. The term is used extensively in the automotive industry, but it can also be used in other markets as well.
NVH problems often occur with items that:
- Open and close
- Don’t move at all
We’ve all experienced that little noise in the car that just won’t go away or strange sounds coming from one of our favorite devices. NVH issues are everywhere – in machines, furniture, cars and appliances. You’re more familiar with them than you think! Sometimes, tape can be the perfect solution to end an otherwise annoying auditory experience. For example, acoustical engineers find specialty adhesive tapes to be an excellent way to mount materials that control NVH.
Moreover, engineers in the automotive industry work on NVH applications each day. Just open the hood of your car’s engine compartment and you’ll see a layer of padding mounted under the hood itself. This might be considered insulation officially, but it’s also there to minimize engine noise. You might notice wires wrapped in some type of cloth tape while you’re searching under there. The cloth tape provides a soft and smooth surface, which reduces squeaks and harshness should the wires rub against something. Other areas in an automobile like the cabin, glove box, dashboard, trunk, doors and steering wheel are all places that have the potential to produce noises.
NVH problems may be a significant concern with other products like generators, compressors, home appliances and gym equipment as well. To reduce or eliminate NVH, materials like foam, cloth, plastics, rubber, felt, tissue and specialty films are used. Pressure-sensitive tapes are a simple and easy product that can aid in addressing these noise problems by securing noise reducers in place without the use of a toolbox. The tape is often supplied in cut shapes to help with application and are ideal for use in tight areas. In addition, pressure-sensitive adhesives can be applied to all of the materials listed above and more, making them ideal for solving noise problems.
Engineers everywhere rely on specialty pressure-sensitive tapes as a fast, cost-effective solution to NVH problems.
