Noise, Vibration, Harshness (NVH)

Noise, Vibration and Harshness

The fight for commercial aircraft orders has lead aerospace manufacturers to seek competitive advantage in two significant areas: fuel economy and increased passenger comfort. Consequently, today’s aerospace engineers are more concerned with noise measurements than their predecessors were. By improving interior sound quality, engineers increase passenger comfort and the desire to fly in next-generation airliners. In addition, by reducing exterior noise, the designer can improve the aircraft’s acceptance in urban settings where air traffic is growing rapidly.

Polytec vibrometers are the cutting-edge choice for leading aerospace companies eager to make NVH measurements on their newest aircraft.
