The deterioration of the sound insulation performance of the DLW due to the mass-air-mass resonance can be improved by the vibration control. In spite of that, setting the vibration absorbers in the cavity causes the movement of the original resonance to the other frequency band and the ...

The sound insulation performance of double-layer wall reduces because of a mass-air-mass resonant problem. To solve this problem, applying vibration absorbers in double-layer wall is a solution to improve the sound insulation performance at resonant frequency band. In theory, we simply modeled a ...
