Brunette Girl Shows Off Her Body On The Floor

Floor vibration is a problem with floors. Wood floors tend to pass sound, particularly heavy footsteps and low bass frequencies. Floating floors can reduce this problem. Concrete floors are usually so massive they do not have this problem, but they are also much more expensive to construct and must meet more stringent building requirements due to their weight.
The flooring may need protection sometimes e.g. a gym floor alternately used for seating in a graduation ceremony. A gym floor cover can be used to reduce the need to satisfy incompatible requirements.
