Abstract: Numerous studies have demonstrated that foldable structures derived from origami-inspired patterns can act as acoustic waveguides and be developed into acoustic metamaterials. Foldable structures are of particular interest due to their potential as tunable or adaptable waveguides. Curved-crease origami patterns have the advantage of requiring fewer creases and giving rise to a wider variety of complex geometries, yet few studies have explored curved-crease designs as acoustic metamaterials. Through a series of computational simulations of acoustic experiments, this paper aims to demonstrate that geometries which arise from curved-crease origami patterns can manipulate acoustic waves through reflection and have a significant effect on sound. By calculating the acoustic ray-tracing solution on variations of the same curved-crease Miura pattern, it becomes clear that curved-crease geometries can reduce reverberation time and loudness– changing the behavior of sound and the perception of noise. We found that altering curved-crease geometries could result in different impacts on acoustics waves. This indicates that curved-crease origami geometries can be developed into acoustic metamaterials and their ability to mitigate noise could have applications for the design of noise-reducing sound barriers.
