Automotive Interior Acoustic Material Testing
topic
Automotive acoustic material testing combines absorption tube, dynamic stiffness, airflow resistance, and statistical energy analysis methods to characterise headliners, carpet systems, door panel fabrics, and seat upholstery for their contribution to vehicle interior noise levels across road noise, powertrain, and wind noise frequency ranges.
Role
Provides the multi-parameter acoustic characterisation data used in automotive transmission loss and interior noise prediction models, enabling early design-phase selection of textile material combinations that achieve target interior sound quality without exceeding mass or cost constraints.
