Noise, vibration and harshness (NVH) testing on the factory floor poses its share of challenges. With all that industrial background noise, it can be almost impossible to pick up specific sounds such as clicks, whirrs or buzzes. Placing a microphone close to the part doesn’t help.
People with mobility issues that require them to use a wheelchair spend a big part of their day on those wheels. With a motorized chair, noise or vibration can quickly become an irritant and a distraction.
Manufacturers want to catch these issues before a unit leaves a factory, rather than having to deal with a return and an unhappy customer.
Unwanted noise or vibration affects customer satisfaction. It can also reveal part and assembly defects or identify a poor design.
