What is NVH?
NVH stands for noise and vibration harshness. Noise is any unwanted sound heard inside or outside of a running vehicle, while vibration refers to uncomfortable movement felt by drivers and passengers. Harshness describes the subjective degree of discomfort associated with noise and vibration. To provide our customers with top-notch products and services, SMI works to address all sources of NVH generation.
The following factors are potential contributors to NVH:
- Mechanical and electrical systems
- Interaction with road surfaces
- Airflow over the body of the vehicle
Vehicle manufacturers perform tests to measure both interior and exterior NVH. Interior NVH refers to the testing of noise and vibration experienced inside the cabin of a vehicle, which involves exposing a full vehicle or specific parts to vibrations at different frequencies. This helps fabricators isolate sources of sound and determine optimal shapes for parts and components. Exterior NVH concerns sound emanating from the vehicle that can be heard by people outside. Drive-by noise testing is performed to measure and modify exterior NVH.
Today’s drivers demand a smoother and quieter ride, and we can’t blame them. Because high NVH levels create discomfort for drivers and passengers, reducing NVH can greatly impact the saleability of a vehicle. Seal Methods Inc. strives to fabricate products that minimize NVH as much as possible. We aim to pinpoint and neutralize sources of unpleasant noise, vibration and shaking, covering all points of rider perception involving sound and sensation.
Noise, Vibration, and Harshness (NVH) Applications
NVH reduction is an essential focus of every quality fabrication service. NVH levels have a significant impact on driver and passenger comfort and determines what impression consumers will leave with after a test drive. Consequently, NVH also affects the market value of that vehicle and whether it matches up to industry standards as a viable and competitive product. Additionally, as vibration causes premature wear and tear to automotive parts and systems, NVH can greatly improve vehicle durability. To ensure top vehicle performance and reliability, reputable manufacturers must step up to the plate with relentless innovation regarding NVH modification solutions.
