Title: Investigation on the Acoustic Performance of Current Trunk Load Floor Solutions
text: Different solutions for trunk floors recently presented on the market have been collated and investigated in order to better define the possible features integrated and the acoustic performance of trunk load floors. A description protocol has been devised and applied to systematically categorize the whole set of features potentially characterizing a trunk floor, and the wide range of solutions used with respect to materials, processes and design configurations. The acoustic performance has been specifically addressed with the evaluation of the acoustic absorption on both sides and a specific testing procedure to evaluate the noise insulation capability provided by actual parts. The results of the actual parts acoustic performance measurement campaign show that a substantial improvement in the acoustic function of the trunk floor module can be achieved by the systematic choice of materials, processes, and of the geometry of the part, in compliance with the standard OEMs requirements Some solution trends for vehicle architecture and segment are highlighted, and recommendations to enhance the acoustic performance and the functionality of trunk floors are provided.
