10dot20 Acoustic Test Through Concrete Slab

A 4 pound hammer was used to generate noise through the 200mm concrete slab, into the room below.

The generated noise was measured in the room below to establish the effects of no system (red), the 10mm system (green), and the 20mm system (blue)

4lb hammer striking the floor with no system in place, with the 10mm 10dot20 system and with the 20mm 10dot20 system:

Audio:

 

  • This audio is recorded in the room below, together with the acoustic data collected on noise levels (below)
  • The loud noise (1st noise), is from the 1st strike on an unprotected floor
  • The 2nd noise is using a 10mm 10dot20 system (Substantially quieter)
  • The 3rd noise (very faint) is using a 20mm 10dot20 system (almost inaudible)

  • The graphical data shows the substantial noise reduction through the concrete slab using the 10dot20 system
  • Red = 1st Strike no protection
  • Green = 2nd Strike using 10mm system
  • Blue = 3rd Strike using 20mm system
