  • Patent number: 7074287
    Abstract: The invention relates to a method of producing and checking a double-resonator honeycomb acoustic panel. The aforementioned panel is characterised in that, following the assembly of the two honeycombs and the partition and prior to the assembly of at least one of the two liners, the perforation rate of said partition is checked by scanning same with digital camera. The successive images thus obtained are transmitted to a computer which determines the perforation rate T of the partition by applying formula T=N1/N, wherein N1 is the number of pixels that correspond to the holes and N is the number of pixels in the image.

  • Publication number: 20050178489
    Abstract: The invention relates to a method of producing and checking a double-resonator honeycomb acoustic panel. The aforementioned panel is characterised in that, following the assembly of the two honeycombs (30, 50) and the partition (40) and prior to the assembly of at least one of the two liners (20, 60), the perforation rate of said partition (42) is checked by scanning same with digital camera (84). The successive images (92) thus obtained are transmitted to a computer (94) which determines the perforation rate T of the partition (40) by applying formula T=N1/N, wherein N1 is the number of pixels (100) that correspond to the holes (42b) and N is the number of pixels in the image (92).
