The invention relates to a covering device (1) for at least partially covering a body region (50) of a motor vehicle, in particular an interior floor (54) of the body. The covering device (1) comprises a cover element (10), a damping material (20) for at least partially absorbing acoustic energy is arranged on a side of the cover element (10) at least in some regions. The damping material (20) has an acoustic wave absorbance of at least 0.9 in a frequency range of 2000 Hz to 3000 Hz, in particular when the material thickness is greater than 10 mm. The invention further relates to a motor vehicle comprising the covering device (1) according to the invention.
本发明涉及一种用于至少部分地覆盖机动车辆的车身区域(50)、尤其是车身的内部地板(54)的覆盖装置(1),所述覆盖装置(1)包括盖元件(10),其中,在盖元件(10)的侧面至少局部地布置有用于至少部分吸收声波能量的阻尼材料(20),其中,阻尼材料(20),尤其是在材料厚度大于10mm时,在2000Hz至3000Hz的频率范围内具有至少0.9的声波吸收度。此外,本发明还涉及包括按本发明的覆盖装置(1)的机动车辆。
