NettetThis method takes the IRF, and assumes that it can be described by a series of complex exponentials: (1) where rAjk is the residue of mode r, related to the complex modal constant and ωr and ξr are the natural frequency and viscous damping ratio of mode r, respectively. Eqn (1) is the inverse Fourier transform of the corresponding FRF: (2) NettetSo the instantaneous intensity due to a sound wave is Above we defined z = p/u. We may rearrange this and use the result above that z = ρv to obtain which we substitute in the previous equation to give For the sinusoidal oscillation we are considering, let the pressure amplitude be p m, so Average intensity and RMS values
