Vehicle Interior NVH Testing - Overview
Vehicle interior noise, vibration and harshness (NVH) involves a number of different tests – all related to noise inside the vehicle originating from road, body, chassis and components of the vehicle.The main focus areas are:
Vehicle interior noise, vibration and harshness (NVH) involves a number of different tests – all related to noise inside the vehicle originating from road, body, chassis and components of the vehicle.The main focus areas are:
- TOTAL INTERIOR NOISE
A way of testing the general experience of a vehicle’s acoustic comfort. - ROAD NOISE
Testing related to how road excitation contributes to the interior noise both structure-borne and airborne – depending on well-defined road surfaces and tires. - THE SOUND PACKAGE
An area that affects most of the NVH areas. - COMPONENT NOISE
Concerns all additional systems like the heating, ventilation and air conditioning (HVAC) system, power windows, etc. These are mostly electrical or driven by the engine belt, and sometimes hydraulic. Read about electric applications here. - BRAKE NOISE
A chassis-related noise and a big problem for car manufacturers. - COMPUTER MODEL VALIDATIONS
Testing on prototype parts or vehicles.
