Acoustic Testing is performed to determine if the material can resist the specified Acoustic environment. It must resist this environment without degradation of its functional performance and/or structural integrity. Acoustic Testing or Acoustic Emission Testing is the measurement of sound emissions radiating from the equipment under test. In other words, how loud is the equipment?

NVH, which stands for Noise, Vibration, and Harshness, is the study of the noise and modification vibration characteristics of vehicles and is basically a measure of how much unpleasant aural and tactile feedback the vehicles deliver as you drive. NVH testing enables early recognition of NVH phenomena, which can then be avoided early during the development stage of the powertrain. This later makes driving in the production vehicle more comfortable and serves to avoid complaints and a loss of image.

The severity of the drop testing can be affected by a variety of factors, including the height of the fall, the surface on which the object lands, and the shape and composition of the object.

Shape and composition are two additional factors that affect severity. Objects with sharp edges or points are more likely to suffer damage than those that are smooth and round. Additionally, objects made of sturdy materials are less likely to break than those made of weaker materials.

Electric vehicles are clearly becoming an expanding part of the automotive scene, assuring low or no emissions, conceivably low cost of fuel from the power grid, yet they will continue to drop us safely from a place to another. However, electric vehicle design and manufacturing is a clear paradigm shift for the Automotive Industry: new technologies, new drive systems and test plans.
