What are the most effective approaches for mitigating noise transmission in a residential apartment gym setting? Specifically, I am examining both structure-borne vibrations and airborne sound transmission associated with typical gym equipment, such as free weights and resistance machines. It would be valuable to compare the performance of various sound-absorbing materials, isolation pads, and flooring under impact loading conditions. Additionally, any insights on integrating acoustic treatments within the modular gym layout—while maintaining functional durability and safety standards—would be highly appreciated, particularly in terms of installation best practices and material lifecycle performance in a high-impact, moisture-prone environment.
