Unwanted acoustic signals within a vehicle cabin degrade user comfort and audio clarity. Mitigating these disturbances improves the perceived quality of the internal environment and communication systems.

Audible noise generated during battery module operation or charging cycles. Eliminating these acoustic emissions improves passenger comfort in electric vehicles.

Standard insulation materials fail to block low-frequency sound waves without excessive mass. Overcoming this limitation allows for quieter vehicle cabins and equipment without compromising space or weight efficiency.

Inconsistent measurement environments and signal interference prevent reliable assessment of acoustic integrity. Standardizing these conditions ensures precise identification of structural or electronic noise defects.
