The audible noise problem caused by airflow through the intercooler used for a supercharger had become a critical issue. The normal approach to reduce the level of audible noise had typically been ineffective and inefficient and resulted in a cost increase.

ASI Solution:

The robust design approach using the ideal function was applied to reduce the variability of airflow through the intercooler while making the design robust to failure modes.

Achieved Benefit:

The optimized function not only cut audible noise by 6 dB (very significant) but also improved the cooling efficiency and reduced the cost by more than $3.50 per unit.
