On the other hands, due to the frequency dependence of attenuation (high attenuation factor for high frequency components) , number of high frequency AE due to fiber breakage (550-650kHz) is drastically reduced for the results of 20 and 30 mm propagation lentgh (Fig.
This in turn increases the attenuation factor of the resonant voltage signal.

1) justify using an attenuation factor of 15 dB between indoor and outdoor noise levels based on Basner et al.
A new term called wall attenuation factor was added to the path loss model, as proposed by Liechty et al.
Based on these derivations and an extensive investigation of measured frequency responses, an approximating formula for the attenuation factor [alpha](f) is found in a form
In this case, the frequency domain solver (with tetrahedral mesh) is used for two main reasons, the structure has relatively small dimensions and the evaluation of the attenuation factor due to conductor loss ([alpha]) is not available in time domain.
