Question

post - test
the purpose of using noise, vibration, and harshness materials includes all of the following except:
a. reduces the level of the nvh source.
b. interrupts noise and vibration paths with barriers or isolators.
c. enables panel flutter.
d. absorbs noise or vibration energy with foam noise absorbers.

Explanation:

Noise, vibration, and harshness (NVH) materials are used to mitigate NVH - related issues. Reducing NVH source levels, interrupting noise and vibration paths, and absorbing noise or vibration energy are their purposes. Panel flutter is an unwanted vibration phenomenon and enabling it is not a purpose of NVH materials.

Answer:

C. Enables panel flutter.
