The net result is a change in the intensity of the sound. The sound pressure does not decrease as rapidly as it would in a free field. In other words, it decreases by less than 6 dB each time the distance from the sound source doubles. Far from the noise source – unless the boundaries are very absorbing – the reflected sound dominates.
