  • Patent number: 10490179
    Abstract: The present invention contemplates regularly spaced or variable width slats having equal width, but with heights determined by an inverted QR sequence, which converts focusing concave areas into beneficial, diffusing convex areas for improved diffusion, especially in the near field. The inverse sequence provides longer resonator necks, between adjacent slats, needed to provide a lower average resonant frequency. Slats are uniformly spaced with inverted QR slat heights have widths determined by the ground states of a Bernesconi sequence. Uniformly spaced, inverted QR slat heights have widths determined by the same QR sequence used to determine heights. Alternatively, uniformly spaced, inverted QR slat heights have widths determined by a Prime 7, primitive root sequence. The uniformly spaced slats have curvilinear forward facing surfaces with their heights based on either a regular or inverted QR sequence, as well as a primitive root or other number theory or optimized sequence.

  • Patent number: 9508334
    Abstract: The essence of the present invention is that the thickness of a diffusive fascia of an acoustical treatment is directly correlative of the transition frequency between absorption and pure diffusion. Applicant has found that the thicker the fascia, the lower the transition frequency. For a fascia 600 microns thick, the transition between absorption and diffusion is at about 250 Hz; for a fascia having a thickness of 300 microns, the transition frequency is at about 500 Hz; for a micro-perforated fascia having a thickness of 150 microns, the transition frequency is at about 1,000 Hz; for a fascia having a thickness of 100 microns, the transition frequency is at about 2,000 Hz. An acoustical treatment is created taking these criteria into account. A method of making is also disclosed.

  • Patent number: 9284728
    Abstract: A honeycomb panel laminate includes a sound absorbing face made of a foam, a sound absorbing layer, and a sound insulating face made of a foam. The sound absorbing layer is composed of a honeycomb material and a layer obtained by filling spaces with a hard foam material. The honeycomb material is bonded to the sound absorbing face by applying an adhesive to edges of the honeycomb material of the sound absorbing layer and pressing the edges against the sound absorbing face so that the edges bite into the foam. The sound insulating face is obtained by applying an adhesive allover a surface of the sound insulating face that makes contact with the honeycomb material and pressing opposite edges of cell walls of the honeycomb material against the sound insulating face so that the opposite edges bite into the surface, having the adhesive, of the foam.
