Panel contribution analysis was combined with scale modeling to predict the sound pressure level at different customer locations in a bakery. The primary sources of noise are three similar heating, ventilation and air conditioning (HVAC) units. Each unit was discretized into several patches and the volume velocity for each panel or patch was measured using sound intensity scans. Vibro-acoustic transfer functions were then measured between the panels and two different customer locations for the baseline case and a 1/10 scale model. Panel contribution analysis was used to predict noise levels and then to predict the contribution from each HVAC unit.
