In the measurement of sound insulation following standards UNE EN ISO 140-4 and 140-5 the uncertainty of the final magnitude is mainly associated to the average sound pressure levels L2 measured. A parameter what allows us to quantify the spatial variation of the sound pressure level is the standard deviation of the pressure levels measured at the different points of the room. In this work, we propose a theoretical calculus of this standard deviation as a combined uncertainty of the standard deviation already proposed in the literature focused in the room geometry and the standard deviation associated to the wall vibrational field. | |
