Abstract: | The prediction of sound levels inside internally complex enclosures is extended to include transmission through walls. The sound field is estimated from the spatial variation of phonon density which is calculated by using a random walk technique. This statistical geometrical method also includes consideration of air attenuation and specular reflection of sound from walls whose individual random incidence absorption coefficients are individually known. Solutions agree with experimental results obtained in models, to within, on average, 4 dB. |
