In general human activities like walking, dancing and running have forcing frequencies in the range of 1.0 to 3.0 Hz.

Resonate frequencies in wooden beam floor constructions indicated:

• Joist span 3 m - 12 Hz
• Joist span 6 m - 9 Hz
• Joist span 9 m - 7 Hz
• Joist span 12 m - 6 Hz
• Joist span 18 m - 5 Hz

Resonate frequencies for concrete floors on the ground ranges 10 - 100 Hz, depending the ground below: 

• Sand - 15 - 25 Hz
• Clay, wet - 15 Hz
• Clay, hard - 30 Hz
• Gravel - 20 - 25 Hz
• Limestone - 35 - 45 Hz
• Solid rock - 40 - 50 Hz
