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?

To control vehicle noise emissions, vehicle manufacturers are required to measure Pass-By Noise according to the regulations to ensure that their vehicle *noise emissions are within the prescribed limits. The regulations are coordinated by the United Nations Economic Commission for Europe Working Party on Noise and Tyres for its 56 member States in Europe, North America, and Asia.

*Noise is unwanted sound or unwanted disturbance in an electronic signal. Acoustic noise is energy transmitted to the air that causes an audible disturbance.
