The paper presents stages of developing a prognostic model for implementing noise protection in an industrial hall. The main source of vibroacoustic problems is the glass hardening furnace, which was installed in a new production hall. It generates vibroacoustic problems at the furnace operators' work stations and at work stations at other devices placed in this hall and in the adjacent hall. These problems are mainly result from mistakes made during the preparation of the furnace placement, as well as the assembly of the machine and accessories. The conducted vibroacoustic tests were aimed at diagnosing problems and developing appropriate ways to minimize the risk of noise and vibration hazards. The basic research tool was to create the correct hall acoustic model, determine the sound power of partial sources and calibrate the model. Modelling the sound protection efficiency of each noise reducing element has allowed the selection of appropriate solutions in terms of acoustic efficiency and approximate application costs. Measurements were carried out according to standard procedures. The article presents only some of the results of vibroacoustic tests directly related to the developed acoustic model. Analysis of vibration paths and noise propagation, indication of assembly defects is a recommendation to formulate vibroacoustic requirements for newly installed devices.
