Abstract Based on the efficient sound absorption characteristics of Helmholtz resonance structures in the range of medium
and low frequency acoustic waves, this paper investigates an effective solution for light timber construction walls
with acoustic problems. This study takes the light timber construction wall structure as the research object. Based
on the Helmholtz resonance principle, the structure design of the wall unit, impedance tube experiment and
COMSOL MULTIPHYSICS simulation calculation were carried out to obtain the change rule of acoustic performance of the Helmholtz resonance wall unit structure. The research results show that the overall stability of sound
insulation of the… More >
