A few slits on the splitter
Combination type with differenet width of splitters.
High sound absorption effect at the low and middle frequencies
due to increase of sound absorption area.
High sound absorption effect at the low and middle frequencies
due to helmholtz effect induced by slits on the splitter.
Optimum design by appropriate arrangement of slit volume and
quantity as per resonance frequency.
High sound absorption at the overall frequencies compared with
general sound attunator.
