This can be a big problem for gymnasiums, especially for free weight areas and treadmills where the impact forces can be very high. If not treated correctly, thuds and similar noises from can be clearly heard and cause a disturbance.

There are many products and solutions on the market, most based on rubber or foam layers. These layers are effective at reducing noise in the gym itself and preventing floor damage but are not effective at preventing impact noise passing into the structure. This is because these materials are too heavily damped and too slow to respond to the low frequency energy of most concern. The only solution is to isolate the floor by using metal springs. Springs react instantly as they are un-damped and very effective against the low frequencies of most concern.

We would always recommend a floating floor supported by springs for free weight zones. Decades of experience have shown that this is the only viable option for controlling impact noise. There are many ways to build such floors because every building and project is different but we will work with you to provide the optimum solution.
