Novel slow-sound lattice absorbers based on the sonic black hole

[Display omitted] •The work presents a slow-sound lattice sound absorber with sonic black hole plates.•Samples were printed successfully using the vat photopolymerization technique.•Sound absorption performances of the proposed lattices outweigh the truss lattices.•The proposed lattices exhibit both...
