Noise from automotive air handling systems is an important issue for driver and passenger comfort. This study was undertaken to quantify the flow noise from the blower and remaining system, and to develop an analytical predictive model for airflow noise. Tests were conducted on four different vehicle Air Handling Systems (AHS) comprised of blower, heat exchangers, ducts and panel registers. Flow and noise data were measured. Test results suggest that overall noise is dominated by blower noise. A predictive model for airflow noise was developed. This model suggests system pressure drop (Delta p) and system airflow (q) being dominant parameters in the noise predictions. The noise variation scales as flow velocity to the power 5.75. The developed model for flow noise can be very useful in the design process to estimate noise levels for new systems from CFD/CAE analyses.
