Abstract: This research studied the flow induced noise by the CFD program fluent as the first step towards the simulation of snoring. Three verification cases included turbulent flow in pipe and turbulent flow through circular orifice in pipe using axial symmetric domains. The case study on flow induced noise using broadband noise source mode was modeled for acoustic power generated by turbulent flow through circular orifice at 8 air inlet velocities 14, 20, 28, 32, 45, 56, 68 and 75 m/sec. The results were compared with existing experimental data. Acoustic power can be well predicted at the mean velocity range of 32-75 m/sec, this made the model unsuitable for the desired purpose which occurred at a low speed.
