Construction with timber is becoming increasingly popular, partially due to its environmental benefits in comparison to steel and concrete. This is especially true for cross-laminated timber (CLT) panels – an engineered wood product consisting of stacked timber lamellae oriented perpendicularly to each other. CLT panels have high stiffness in comparison to its mass, which leads to a sensitivity to dynamic loads, such as footfall loading, and is thus prone to vibro-acoustic problems. Enhancing the design of these panels is therefore of importance in order to mitigate low-frequency vibrations and structure-borne noise. This study aims at numerically investigating the possibility of mitigating the vibration response of CLT panels by introducing elastomer layers in-between the timber layers, as well as by exchanging the timber material from the typical spruce to oak. It was shown that by integrating elastomer layers and/or using oak lamellae in CLT panels, the vibration response can be reduced in the frequency range 1–120 Hz.
