Noise, vibration, and harshness (NVH) testing is a type of mechanical testing that is used to evaluate the potential for a product to generate noise, vibrations, or harshness during operation. This testing is typically used to assess the potential for products to generate noise that could be disruptive or annoying to users, or to assess the potential for products to generate vibrations that could be harmful to users.
NVH testing is typically carried out using a variety of sensors and instruments, including accelerometers, microphones and strain gauges. The data collected is then analyzed to identify the source and nature of the noise, vibration or harshness.
The purpose of NVH testing in Automotive sector is to ensure that a vehicle meets acceptable levels of noise and vibration. This type of testing is important because it can help to identify potential problems with a vehicle before it goes into production. NVH testing can also be used to improve the quality of a vehicle by making sure that it meets customer expectations.
There are many different types of NVH testing in vehicles, but some of the most common include: –Engine noise testing, Exhaust noise testing, Wind noise testing, Road noise testing, Tire noise testing, Suspension noise testing, Body panel noise testing, Interior noise testing
