Refers to the thickness of the current floor.
Dynamic modulus of elasticity
The modulus of elasticity is a material-dependent variable that shows the relationship between mechanical stress and deformation. Also goes by the name Young's module.
Refers to the density of the current floor layer, ie how heavy it is.
The radiation factor is a measure of how well the bending wave field in the beam is transferred to the surrounding air. For a frequency greater than the critical frequency, the factor is set to 1.
The loss factor describes the relatively lost energy per radius.
Sound produced at, for example, the floor. The sound is transported through the structure to the air on the other side.
