    Abstract: A method for measuring a first angular specific sound absorption spectrum of a first sound absorbing sample. The first sound absorbing sample has a predetermined random incidence sound absorption spectrum. The angular specific sound absorption spectrum is determined from a sound wave incident on a surface of the first sound absorbing sample with a predetermined angle of incidence that is greater than zero degrees from a plane parallel to the surface of the first surface. A first weighting factor that provides a fit of the angle specific sound absorption spectrum of the first sound absorbing sample to the predetermined random sound absorption spectrum is then determined. Next, a second angular specific sound absorption spectrum of a second sound absorbing sample at the predetermined angle of incidence is determined. The weighting factor is then used to determine the random specific sound absorption spectrum from the angle absorption spectrum of the second sound absorbing sample.

    Abstract: A sound insulation system for use with a vehicle includes a layer of fibrous padding material having a first surface and an opposite second surface. The first surface includes multiple spaced apart recesses. The second surface includes a substantially flat surface portion that extends over two adjacent recesses. The multiple recesses are configured to define multiple voids when the sound insulation system is mounted in the vehicle, thereby enhancing acoustical performance of the sound insulation system.

    Abstract: A method of making a sound insulating layered composite structure by roll coating a padding layer with an emulsion which may then be solidified to form a layer disposed over at least a portion of the padding layer. The emulsion may be applied using various devices and applied at thicknesses as to provide the capability to tune the acoustic performance of the composite.
