Summary: This study develops the concept of a metahouse chamber for multiple band noise insulation, using a ventilated structure based on the idea of metamaterial systems. Broad stop-bands are achieved through strong coupling between pairs of Helmholtz resonators in the structure, demonstrating an averaged transmission attenuation of -18.6 dB within the spectral range from 1500 to 16 500 Hz both numerically and experimentally. The sparseness of the structure and the possibility of using optically transparent materials suggest the potential for partial optical transparency depending on the arrangement of structural elements.
