  • Publication number: 20070287001
    Abstract: An airborne sound-absorbing engine compartment lining for motor vehicles comprises an open-cell, air-permeable foam material layer made from plastic and having a front side and a rear side. The foam material layer is provided on its rear side with a fiber layer made from mineral fibers, the foam material layer having a thickness of less than 6 mm and a specific flow resistivity in the range from about 100 to 1,200 Ns/m3. The fiber layer has a thickness of more than 6 mm and a mass per unit area of less than 800 g/m2.

  • Patent number: 6789646
    Abstract: Acoustical attenuating devices (52) and method of forming them. The attenuating devices (52) include an exterior layer (64), a sound absorption layer (66), and multiple perforated layers (68) coupled to the sound absorption layer (66). The perforated layers (68) include a perforated structural layer (70) and a perforated substrate layer (72). The perforated structural layer (70) and the perforated substrate layer (72) provide structural stiffness and define multiple resonating tubes (88) that attenuate sound.
