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 and other noises associated with mechanical devices. The term is used extensively in the automotive industry but can also be used in other markets as well. Acoustical engineers find specialty adhesive tapes to be a great way to mount NVH control materials.
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 noises coming from some other device. NVH applications are everywhere – in machines, furniture, cars, appliances, and more.
Engineers in the automotive industry work on NVH applications every day. Just open the hood to your car’s engine compartment and you’ll see a layer of insulation mounted under the hood itself. This might be considered insulation, but it’s also there to minimize engine noise. You might also see wires wrapped in some type of cloth tape. 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, steering, and more are all areas that have the potential to produce noises. NVH problems can also be a concern with other products like generators, compressors, home appliances, gym equipment and others.
To reduce or eliminate NVH, materials like foam, cloth, plastics, rubber, felt, tissue and specialty films are used.
Like with many other applications, pressure-sensitive tapes are simple and easy to use. Generally no tools are needed. In addition, pressure-sensitive adhesives can be applied to all of the materials listed above and more, making them ideal for solving noise problems. Pressure-sensitive adhesive tapes are often supplied in cut shapes to help aid application and are ideal for use in tight areas.
Engineers everywhere rely on specialty pressure-sensitive tapes as a fast, cost-effective solution to NVH problems. Think about how specialty pressure-sensitive products can solve your NVH problem!
