  • Motor-vehicle underbody liner to absorb rolling noise on the vehicle lined therewith
    Patent number: 11161463
    Abstract: A motor-vehicle underbody liner, encompassing a planar porous open-cell carrier component; the carrier component being embodied for mounting onto a motor-vehicle underbody and for being carried along therewith; the carrier component including an installation side that faces toward the motor-vehicle underbody during operation as intended, and a liner side that faces away from the motor-vehicle underbody during operation as intended; the carrier component being adjusted, by suitable densification of its open-cell material, to a sound absorption behavior having a sound absorption maximum in a frequency range from 800 Hz to 1250 Hz; there being arranged on the installation side of the carrier component an additional absorber component having a sound absorption behavior whose sound absorption maximum is also located in a frequency range from 800 Hz to 1250 Hz.
