Evaluation of the vibration performance response of insulating floor panels under human walking conditions

The use of lightweight prefabricated floor panels has grown considerably over the last two decades. Previous studies have shown a detrimental vibrational response of these floors under human walking conditions, resulting in user complaints. The present study evaluates the vibration performance of a...
