PREDICTION OF RESPONSE PROBABILITY DISTRIBUTION FOR VARIOUS TYPE SOUND WALL SYSTEMS CONTAMINATED BY A BACKGROUND NOISE

This paper presents a new method of determining the true output response of a system in the presence of background noise and without any artificial error criterion such as the least-squares method. More specifically, a mathematical model of arbitrary sound insulation systems is developed using the well-known additive property of energy or intensity qualities to give a linear system based on noise intensity. Subsequently, a new method of estimating the output response in the presence of background noise is derived. Using the above, a new procedure is developed by which the uncontaminated output response probability function form for arbitrary sound insulation systems can be derived from observed data contaminated with background noise. Last, the effectiveness of the new method is confirmed by applying it to the experimentally observed response data of various types of sound wall systems.
